This package and repository have been deprecated and archived. Its code is folded in to the main AutoMapper repository.
When integration testing with ASP.Net Core, it is very common to use TestServer to start your service as an in-memory host so that you can perform service-level integration tests via a real HttpClient.
However, since AutoMapper 6.2.0 was released this no longer works. Your Startup class is effectively called multiple times within the same process, so the AddAutoMapper() call happens multiple times, so the Mapper.Initialize() call also happens multiple times. This results in an exception in the second test:
System.InvalidOperationException : Mapper already initialized. You must call Initialize once per application domain/process.
at AutoMapper.Mapper.set_Configuration(IConfigurationProvider value)
at AutoMapper.Mapper.Initialize(Action`1 config)
at AutoMapper.ServiceCollectionExtensions.AddAutoMapperClasses(IServiceCollection services, Action`1 additionalInitAction, IEnumerable`1 assemblies)
at MyService.Startup.ConfigureServices(IServiceCollection services)
How can we 'clear out' the AutoMapper statics so that integration testing can be supported in a single process?
I am not sure if I am asking the right question but here is what I wanted to do. Is there a better way to do this?
public static class CustomerExtensions
{
public static CustomerViewModel ToViewModel(this Customer customer, IMapper mapper)
{
return mapper.Map<Customer, CustomerViewModel>(customer);
}
}If I have a profile with a dependency, is there any way of it being automatically picked up by AddAutomapper? I'm currently getting an error about parameterless constructors.
I've tried manually adding it using the cfg => overload of AddAutomapper, but it appears to still try and auto-register the profiles.
Do I have to revert to my own custom setup?
We have somewhat special requirements in our application:
IServiceProvider in our mappingsThe proposed solution to those problems is having a default IMapper<T> where T : IConfigurationProvider or something similar.
We evaluated the following implementations:
IMapper<T> where T : IConfigurationProvider
This seems to be the most flexible solution.
IMapper<T> where T : Profile
There doesn't seem to be a way to merge profiles by using AddProfile from within a profile which makes this solution unusable.
IMapper<T1> where T : Profile and overloads with IMapper<T1, T2>, etc...
Too much boilerplate for us.
The implementation with T : IConfigurationProvider was the most flexible for us even though we need (in the worst case) both a IConfigurationProvider implementation and a Profile derived class for a single mapping, like e.g.:
public class MyProfile1 : Profile
{
public MyProfile1()
{
// Mapping configuration
}
}Someone would be able to create its own class derived from MapperConfiguration:
public class MyConfiguration : MapperConfiguration
{
public MyConfiguration(MyProfile profile)
: base(cfg => cfg.AddProfile(profile))
{
}
}A generic implementation of a profile configuration could look like this (even though I don't really like this solution):
public class ProfileConfiguration<T> : MapperConfiguration where T : Profile
{
public ProfileConfiguration(T profile)
: base(cfg => cfg.AddProfile(profile))
{
}
}
public class ProfileConfiguration<T1, T2> : MapperConfiguration where T1 : Profile, T2 : Profile
{
public ProfileConfiguration(T1 profile1, T2 profile2)
: base(cfg => { cfg.AddProfile(profile1); cfg.AddProfile(profile2); })
{
}
}We add all classes derived from MapperConfiguration and Profile to our service collection which allows us to use IMapper<MyConfiguration> (or IMapper<ProfileConfiguration<MyProfile>>) in a constructor which gets resolved to Mapper<MyConfiguration> (or Mapper<ProfileConfiguration<MyProfile>>) which looks like this:
public class Mapper<T> : IMapper<T>
where T : IConfigurationProvider
{
private readonly IMapper _mapper;
public Mapper(IServiceProvider serviceProvider, T t)
{
_mapper = new Mapper(t, serviceProvider.GetService);
}
public IConfigurationProvider ConfigurationProvider => _mapper.ConfigurationProvider;
// ... remaining implementationAll those types are registered with:
serviceCollection
.Scan(scan => scan.FromAssemblyOf<Startup>().AddClasses(c => c.AssignableTo<Profile>()).AsSelf().WithSingletonLifetime())
.Scan(scan => scan.FromAssemblyOf<Startup>().AddClasses(c => c.AssignableTo<IConfigurationProvider>()).AsSelf().WithSingletonLifetime())
.AddScoped(typeof(IMapper<>), typeof(Mapper<>))The Scan function is from the Scrutor package. This project would/should probably avoid using Scrutor and use its own implementation instead (as it already does).
The usage would look like this:
public class MyController
{
public MyController(IMapper<MyConfiguration> mapper)
{
}
}People struggle with this constantly.
When combining AddAutoMapper(), AddDataReaderMapping(), and Profile classes, a destination object instance's properties are populated with type default values and not with source object values.
(Hopefully this is the right repo for this issue. I wasn't sure if this one or AutoMapper.Data was appropriate.)
IDataRecord shape is similar to
@FirstName NVARCHAR(50),
@LastName NVARCHAR(50),
@UserId INTpublic class User
{
public string FirstName { get; set; }
public string LastName { get; set; }
public int UserId { get; set; }
}Object instance looks like
{
FirstName: "TestFirstName",
LastName: "TestLastName",
UserId: 123
}Object instance looks like
{
FirstName: null,
LastName: null,
UserId: 0

}Either delete UserProfile.cs and modify Startup.cs:
services.AddAutoMapper(config => {
config.AddDataReaderMapping();
config.CreateMap<IDataRecord, User>();
});Or be more explicit in UserProfile.cs:
public class UserProfile : Profile
{
public UserProfile()
{
this.CreateMap<IDataRecord, User>()
.ForMember(destination => destination.FirstName, options => options.MapFrom(source => source.GetString(source.GetOrdinal("FirstName"))))
... etc;
}
}After I upgraded to 5.0.1 from 4.0.1 I get the following error:
Mapper not initialized. Call Initialize with appropriate configuration. If you are trying to use mapper instances through a container or otherwise, make sure you do not have any calls to the static Mapper.Map methods, and if you're using ProjectTo or UseAsDataSource extension methods, make sure you pass in the appropriate IConfigurationProvider instance
I have the following line in startup.cs ConfigureServices:
services.AddAutoMapper(typeof(Startup));
I also have a MappingProfile.cs with the following structure:
public class MappingProfile : Profile {
public MappingProfile() {
CreateMap<....
}
}
This was sufficient in 4.0.1 but apparently not in 5.0.1
Consider returning IServiceCollection from all overloads of AddAutoMapper.
That would allow chaining all calls to the multiple 'AddSomething'.
Same approach is taken by AddSwaggerGen from Swashbuckle.SwaggerGen and AddHangfire from Hangfire.AspNetCore. As well as the packages built by Microsoft.
Add ability to specify lifetime for AutoMapper services:
IValueResolver<,,>,IMemberValueResolver<,,,>,ITypeConverter<,>,IMappingAction<,>,IMapperFor one of my mappings, I need access to some configuration element, so ideally I'd love to be able to do this:
public class MappingProfile : Profile
{
public MappingProfile(IOptions<Settings> options) {
CreateMap<User, EditUserModel>(MemberList.Source)
.ForMember(m => m.Something,
o => o.MapFrom(a => a.GenerateThing(options.SomeConfigItem)));
But that's not supported - can you advise how I might achieve this?
Thanks
I think this may be the reason that cause the System.Reflection.ReflectionTypeLoadException in xunit test project.
When automapper-calling code like ProjectTo<>() is called I receive:
An unhandled exception occurred while processing the request.
InvalidOperationException: Mapper not initialized. Call Initialize with appropriate configuration. If you are trying to use mapper instances through a container or otherwise, make sure you do not have any calls to the static Mapper.Map methods, and if you're using ProjectTo or UseAsDataSource extension methods, make sure you pass in the appropriate IConfigurationProvider instance.
This code used to work before updating a bunch of nugets to the latest versions.
In startup I'm using
services.AddAutoMapper(typeof(Startup));
Just coming from AutoMapper/AutoMapper#2140 I actually got my setup to work as initially expected.
Although, when using static mapping after having done:
services.AddAutoMapper() .AddTransient<CustomResolver, DefaultCustomResolver>();
The mapping configuration looks like:
...
.ForMember(dest => dest.SomeDate, opt => opt.ResolveUsing<CustomResolver>())Ends up with the following stacktrace when mapping with Mapper.Map :
at System.RuntimeTypeHandle.CreateInstance(RuntimeType type, Boolean publicOnly, Boolean noCheck, Boolean& canBeCached, RuntimeMethodHandleInternal& ctor, Boolean& bNeedSecurityCheck) at System.RuntimeType.CreateInstanceSlow(Boolean publicOnly, Boolean skipCheckThis, Boolean fillCache, StackCrawlMark& stackMark) at System.Activator.CreateInstance(Type type, Boolean nonPublic) at System.Activator.CreateInstance(Type type) at AutoMapper.MappingOperationOptions2.CreateInstance[T]() at lambda_method...
It seems that the static mapper does not get/uses the IServiceProvider.GetService method supplied when setting up the IMapper instance in .AddAutoMapper()?
Injecting and using the IMapper instance and doing the same mapping works as expected with the injected Resolver.
Targeting console application to net461 throws Could not load file or assembly error.
I have tried to install following NuGet packages:
AutoMapper.Extensions.Microsoft.DependencyInjection
AutoMapper
Microsoft.Extensions.DependencyInjection
`
// Set DI
var serviceCollection = new ServiceCollection();
ConfigureService(serviceCollection);
var serviceProvider = serviceCollection.BuildServiceProvider();
private static void ConfigureService(IServiceCollection serviceCollection)
{
serviceCollection.AddTransient<IApplicationBusiness, ApplicationBusiness>();
`
Is there a signed version of this assembly? If not, would you be willing to produce one?
Thank you for your trouble.
Would it be possible to add an IApplicationBuilder extension method that adds the functionality that Mapper.AssertConfigurationIsValid() provided to non .NET Core based projects?
I'm envisioning my Startup class to look something like this:
public class Startup
{
public void ConfigureServices(IServiceCollection services)
{
services.AddAutoMapper(typeof(MyMappingProfile));
}
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
app.AssertAutoMapperConfigurationIsValid();
}
}
}
Ideally, this would make the assert exceptions to be thrown when a request is made to the server in much the same way that adding Mapper.AssertConfigurationIsValid() to Global.asax - Application_Start() in .NET based projects did.
NOTE: I did attempt to simply use Mapper.AssertConfigurationIsValid(); however, it did not assert properly. I assume this is due to needing to use the non-static IMapper which does not currently have the AssertConfigurationIsValid() method.
Hello,
I'm having issues injecting IHttpContextAccessor into my custom value resolver. When I try to inject the service using the default dotnet core DI, AutoMapper seems to expect that my resolver uses a default constructor and I get the error message: Property: Url ---> System.MissingMethodException: No parameterless constructor defined for this object.
This is the call in my profile that is throwing the exception:
CreateMap<AppointmentType, AppointmentTypeViewModel>()
.ForMember(model => model.Url,
opt => opt.ResolveUsing<SolutionUrlResolver>())
.ReverseMap();Here's my Resolver:
namespace View
{
public class SolutionUrlResolver : IValueResolver<SolutionEntity, SolutionViewModel, string>
{
public const string URLNAME = "GetAppointmentTypes";
private IHttpContextAccessor _httpContextAccessor;
public SolutionUrlResolver(IHttpContextAccessor httpContextAccessor) {
_httpContextAccessor = httpContextAccessor;
}
public string Resolve(SolutionEntity source, SolutionViewModel destination, string destMember, ResolutionContext context)
{
var url = (IUrlHelper)_httpContextAccessor.HttpContext.Items[BaseController.URLHELPER];
return url.Link(URLNAME, new { id = source.Id});
}
}
}In Startup.cs I have this:
public void ConfigureServices(IServiceCollection services)
{
services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();
services.AddAutoMapper();
services.AddMvc(); ...
When I replace the SolutionUrlResolver with a class that uses a default constructor (and does not reference IHttpContextAccessor) then the exception goes away.
I tried mimicking the way DependencyResolver is written in the test app. I must be missing something simple here but I just don't know what it is.

While scanning an assembly for IValueResolver, IMemberValueResolver, ITypeConverter in AddAutoMapper overloads it would be handy if Automapper could also recognize IMappingAction
I don't want to sound rough, but I would like to know a sample usage to understand why anyone would use this.
What are the benefits of injecting AutoMapper into the DI mechanism of ASP.NET Core? Does it make AutoMapper able to construct object with dependencies using the integrated ASP.NET's DI container?
For now, the only think I have seen is that I can inject an instance of the mapper using a IMapper mapper in the constructor of my controller, but that doesn't offer much advantages. Previously, I used the state Mapper façade.

Adding a possibility to do a AssertConfigurationIsValid(); when automapper is initialized via the services in the startup file.
I'm trying configure Automapper at Startup.cs, but AssertConfigurationIsValid not actually do at application start.
services.AddAutoMapper(cfgExpression =>
{
cfgExpression.AddProfile<MappingProfile>();
cfgExpression.Advanced.BeforeSeal(cfgProvider => cfgProvider.AssertConfigurationIsValid<MappingProfile>());
});
If add Mapper.Configuration.AssertConfigurationIsValid(); after call extension AddAutoMapper AssertConfiguration works as expected.
Is this the correct behavior?

this is my code :
public class UserProfile:Profile
{
public UserProfile()
{
CreateMap<UserViewModel, ApplicationUsers>().ConvertUsing<UserEncryptor>();
}
}
public class UserEncryptor : ITypeConverter<UserViewModel, ApplicationUsers>
{
private readonly IConfigurationRoot _configuration;
public UserEncryptor(IConfigurationRoot configuration)
{
_configuration = configuration;
}
public ApplicationUsers Convert(UserViewModel source, ApplicationUsers destination, ResolutionContext context)
{
if (context==null||source == null) return null;
var aes = new Common.EncryptionAes(_configuration[key: "Keys:AesKey"]);
return new ApplicationUsers
{
UserName = aes.EncryptAes(source.Username),
Email = aes.EncryptAes(source.Email),
PhoneNumber = aes.EncryptAes(source.MobileNumber),
User = new User
{
FirstName = aes.EncryptAes(source.FirstName),
LastName = aes.EncryptAes(source.LastName),
Gender = aes.EncryptAes(source.Gender.ToString()),
ProfileImage = aes.EncryptAes(source.ProfileImage.FileName)
}
};
}
}Note that ApplicationUsers is inherited from IdentityUser Class.
When I tested this mapping,I got this error :
System.NullReferenceException: Object reference not set to an instance of an object.
I know this error is for that some members are not ignored. Something like this
CreateMap<UserViewModel ,ApplicationUsers >()
.ConvertUsing(converter=> new ApplicationUsers(){
Email = converter.Email,
....
});will help me because by default ignore rest of the members but the problem is that if I want to use this kind of code, I cant encrypt my members because I don't access to DI configuration for profile.Because profile is parameter less.
I need something similar to upper code that can implement in ITypeConverter functions.
Anyone has any solution ?

this function broken in v5.0.1 and works in v4.0.1
I feel like it's quite easy to call services.AddAutoMapper() with no parameters and expect for things to Just Work™. Unfortunately, without adding at least a marker type or an assembly to drive the profile discovery, consumers will get a mapping exception later at runtime because no profiles were added to the configuration.
I guess people expect it to work since many of the default, Microsoft-provided extension methods do something when called with no parameters. On the other hand, I totally understand AutoMapper needs information to do its thing properly.
What do you think of adding a check in this overload for marker types and this one for assemblies to verify the array contains at least one element?
Or delegate it to AddAutoMapperClasses to check whether the initialisation action is not null or we have at least one assembly? But then we can't know which extension method the consumer used, hence difficult to give them a specific error message.
Just opening a discussion here, will be happy to provide a PR when/if we agree on something. As an FYI, this comes from that SO question.
Edit:
I just realised that if in an ASP.NET Core app targeting netcoreapp1.0, then the nestandard1.6 flavour is used, so calling services.AddAutoMapper() would call the parameter-less overload that uses the DependencyContext. Same thing happens if the app targets the full .NET framework. I guess we should know more about the setup, then.
Unrelated question, what's the need for a netstandard1.1 build of that library? Can the application use a Startup from another project which would be a class library?
I just upgraded to AutoMapper 6.0.0 and this assembly (2.0.0) and now receive the error:

The specific line of code is:
services.AddAutoMapper(cfg =>
{
cfg.CreateMap<DateTimeOffset, DateTime>().ConvertUsing<DateTimeOffsetConverter>();
cfg.CreateMap<DateTime, DateTimeOffset>().ConvertUsing<DateTimeConverter>();
cfg.CreateMap<DateTimeOffset?, DateTime?>().ConvertUsing<NullableDateTimeOffsetConverter>();
cfg.CreateMap<DateTime?, DateTimeOffset?>().ConvertUsing<NullableDateTimeConverter>();
});
This hasn't changed for a while and is being used in many projects. What solution would you recommend?
I also tried the follwoing with the same issue:
private class DateProfile : Profile
{
public DateProfile()
{
CreateMap<DateTimeOffset, DateTime>().ConvertUsing<DateTimeOffsetConverter>();
CreateMap<DateTime, DateTimeOffset>().ConvertUsing<DateTimeConverter>();
CreateMap<DateTimeOffset?, DateTime?>().ConvertUsing<NullableDateTimeOffsetConverter>();
CreateMap<DateTime?, DateTimeOffset?>().ConvertUsing<NullableDateTimeConverter>();
}
}
public void ConfigureServices(IServiceCollection services)
{
services.AddAutoMapper(cfg => cfg.AddProfile(new DateProfile()));
}
I tried to use the absolute bare minimum code from basically dotnet new mvc && dotnet new xunit where I AddAutoMapper and I also have two tests class using a pretty much empty WebApplicationFactory. I also tossed a single profile in the mvc app. This was incredibly easy to reproduce.
Mapper.Reset(); in my startup did not help, as well as disabling UseStaticRegistration.
If I just use a single WebApplicationFactory then my tests do not fail so is this some weird thread issue with IClassFixture? From my research there should not be two separate instances of a fixture created in xunit but this could be wrong. Somehow, my startup is being initialized multiple times.
Any help is appreciated. I feel like this is an important issue because the official Microsoft tutorial and example shows how to write tests using the new WebApplicationFactory as shown here and anyone with two XUnit test classes inheriting from their implementation of the factory will run into this very error and their tests will fail. For what its worth, I am not running my tests in parallel.
ref #26 (comment)
As of 5.0.1 services.AddAutoMapper(); doesn't register user-defined mapping Profiles from the executing assembly. Immediate subsequent call of Mapper.AssertConfigurationIsValid(); throws an InvalidOperationException:
But 4.0.1 works just fine.
Env: ASP.NET Core 2.1.
Background
We have a Visual Studio solution with multiple projects. The main project is an ASP.NET Core Web Application, which currently solely targets .NET Framework. The other projects are partly .NET Core Class Libraries (also only targeting .NET Framework) and normal Class Libraries (especially for COM interop services).
So far we used to have AutoMapper automatically scan the assemblies of the default DependencyContext for any contained profiles etc.
Problem
With the latest changes for version 1.1.0, in particular this commit, the compatibility with normal Class Libraries has been broken. These are not contained any more in the list of assemblies to scan, even if they reference the AutoMapper library and contain profiles etc.
Cause
The problem comes from the fact that the RuntimeLibrary.Dependencies for these libraries does only contain other normal Class Libraries, not the AutoMapper assembly. The Where condition thus excludes these.
Suggestion
You could handle the normal Class Libraries differently (i.e. always include them), notable from the different Type they have, being "msbuildproject". The .NET Core ones have "project".
Internal types are not auto-discovered when using the default behavior of AddAutoMapper()
When I run the dotnet ef database drop command, it throws exception:
An error occurred while calling method 'BuildWebHost' on class 'Program'. Continuing without the application service provider. Error: Mapper already initialized. You must call Initialize once per application domain/process.
Unable to create an object of type 'ApplicationDbContext'. Add an implementation of 'IDesignTimeDbContextFactory<ApplicationDbContext>' to the project, or see https://go.microsoft.com/fwlink/?linkid=851728 for additional patterns supported at design time.
It seems to caused by services.AddAutoMapper() in ASP.NET Core ConfigureServices method. When I comment this line, command works fine. I tried other commends like database update or migrations, this problem won't happen.
Solution from #36 works. But I think the default extension method shouldn't break EF Core CLI.
I'm using AutoMapper 6.2.2 and AutoMapper.Extensions.Microsoft.DependencyInjection 3.2.0, with Entity Framework Core 2.1.0-preview1-final.
Probably an odd one that no-one else will run into...
If I have only "AutoMapper.Extensions.Microsoft.DependencyInjection" defined in the dependencies section of a project.json the project will compile and run but not pick up any assemblies to load configuration from.
Adding an explicit reference to "AutoMapper" to the project.json fixes this.
I don't think a change to code is required, though it might be worth adding something to the Readme / any tutorials to explicitly reference AutoMapper.
Hi, is there a way you can change the code in this line here so we can also inject services inside profiles ?
I don't believe it is currently possible to correctly register dependency injection with AutoMapper in .NET Core. Consider the following code inside ConfigureServices:
services.AddAutoMapper(cfg =>
{
cfg.ConstructServicesUsing(services.BuildServiceProvider().GetService);
});
I have a value resolver that depends on Entity Framework's database context. The call to services.BuildServiceProvider() returns a new instance of service provider that has its own collection of services. Here is the relevant code from ServiceCollectionContainerBuilderExtensions:
return new ServiceProvider((IEnumerable<ServiceDescriptor>) services, options);
I don't think there is any other way to get a service provider inside Configure. This means that AutoMapper will inject a different instance of database context than the one used by my domain services. This causes issues when both contexts use the same entity. I can probably hack my way around this somehow, but the same issue applies to all injected services. If you set up a service as a singleton, then you end up with two "singletons" (I have verified this using a static field incremented in the constructor).
I think this can be resolved by adding AutoMapper middleware in ConfigureServices and configuring it in Configure. Configure has access to the default, and already instantiated, service provider. That way you could pass this provider to ConstructServicesUsing.
To sum it up, the code could look something like this:
public void ConfigureServices(IServiceCollection services)
{
services.AddAutoMapper();
}
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
app.UseAutoMapper(cfg =>
{
cfg.ConstructServicesUsing(app.ApplicationServices.GetService);
});
}
In integration tests (with MSTest & TestServer), all tests throw InvalidOperationException "Cannot resolve scoped service 'AutoMapper.IMapper' from root provider". Changing the IMapper registration from Scoped to Transient allows the tests to pass.

}Big problems with registering statically:
services.AddAutoMapper is called on an instance of a IServiceCollection, but Mapper.Initialize is static. I can't know if AddAutoMapper has already been called with against the same IServiceCollection instance. Even if I track if I've already initialized AutoMapper statically, I can't know if it's against the same set of services.
Just far more trouble than it's worth, I think.
Please consider adding support for calling AddAutoMapper() multiple times.
Reason:
We have very modular application design, each module is responsible of registering own mapper profiles.
Currently services.AddAutoMapper(i => i.AddProfile(...)); cannot be called multiple times because of Mapper.Initialize being overwriting previous setup. Additionally services are not added with TryAdd...
In my ASPNET Core 2.0 project, when adding a Cache Dependency to my CustomResolver, such dependency is not resolved. I have a complex dependency structure and many mapping profiles which I register as below:
`
services.AddSingleton<ICacheService, CacheService>();
var config = new MapperConfiguration(cfg =>
{
cfg.AddProfile(new CreateProductProfile());
cfg.AddProfile(new ChangeProductProfile());
cfg.AddProfile(new SharedProfile());
cfg.AddProfile(new RetrieveProductProfile());
});
var mapper = config.CreateMapper();
services.AddSingleton(mapper);
`
My resolver CustomResolver has below code:
`
public class ProductIdResolver : IValueResolver<Request.Product, Entities.Product, int>
{
private readonly ICacheService cacheService;
public ProductIdResolver(ICacheService cacheService)
{
this.cacheService = cacheService;
}
public Entities.Product Resolve(Request.Product source, Entities.Product destination, int destMember, ResolutionContext context)
{
if (source == null)
return null;
var product = Mapper.Map<Entities.Product>(source);
product.Id = TranformProductId(source);
return product;
}
private int TranformProductId(Request.PBI source)
{
var frombase = cacheService.GetProducts().FirstOrDefault(p => p.Sku == source.Sku);
if (frombase == null)
throw new NullReferenceException("Invalid Product");
return frombase.Id;
}
}
`
The resolver reference is inside my SharedProfile, which is called by both Create and Change profile (I broke those profile classes into a third one for code re-using).
The problem is that my CacheService is not being resolved by DI and I always get an "Error mapping types" exception.
For reference, my code works if I remove the CacheService object.
How can I successfully inject that dependency into my custom resolver?
In the readme
I see the source code below：
return services.AddScoped<IMapper>(sp => new Mapper(sp.GetRequiredService<IConfigurationProvider>(), sp.GetService));
but i want to use singleton ?
Hello, gentlemen.
Thank you for a Great Tool.
Is it possible to add a resolving of profiles with DI? When I am trying to use .AddAutoMapper(expression => expression.AddProfile<AutoMapperProfile>) extension method, it requires an parameterless constructor because of where TProfile : Profile, new() restriction in the IMapperConfigurationExpression interface. Also I can't add an instance of my AutoMapperProfile class with .AddProfile(autoMapperProfile), because of resolving of a profiles by their types anyway ( https://github.com/AutoMapper/AutoMapper.Extensions.Microsoft.DependencyInjection/blob/master/src/AutoMapper.Extensions.Microsoft.DependencyInjection/ServiceCollectionExtensions.cs#L206). As workaround I am using this approach:
.AddTransient<IMapper>(provider => new Mapper(new MapperConfiguration(expression => expression.AddProfile(provider.GetService<AutoMapperProfile>()))))
.AddTransient<AutoMapperProfile>()
but it would be nice to use out of the box .AddAutoMapper method from ServiceCollectionExtensions.
Thanks a lot
Hi Jimmy,
It looks like in v5 of this library you have taken on an AspNetCore dependency, but we use this in an MVC5 apps, console apps, as well as AspNetCore apps. It looks like the reason for the dependency is the ConfigurationAssertMiddleware. Do you think it makes sense for this to be in a separate package? It seems weird to me to have AutoMapper.Extensions.Microsoft.DependencyInjection depend on an AspNetCore package.
Thanks! :)
Hello,
I'm using this package in my dotnet core application and I don't understand how to reference an assembly this way: services.AddAutoMapper(<my_assembly>)
The only way I know how to reference an assembly is with the using keyword. I realize this is probably a C# question and not a question about this package, but google keeps pointing me to the using keyword.
I'm looking for the magic words to search for in google or a concrete example I can study that uses services.AddAutoMapper(<some_assembly_in_a_solution>)?
Thanks.
Updated to the latest AspNetCore.Mvc versions 1.1.2 with using the framework net452 I get the error at the bottom.
The setup in Startup.cs
public void ConfigureServices(IServiceCollection services)

services.AddCors(options =>

options.AddPolicy("AllowSpecificOrigin",
builder => builder.WithOrigins("http://localhost:16964"));
});
services.AddMvc();
services.Configure<MvcOptions>(options =>
{
options.Filters.Add(new CorsAuthorizationFilterFactory("AllowSpecificOrigin"));
});
services.AddAutoMapper();
... other services
}

I upgraded my project to V3.x.x and it crashes in the mapping like:
Mapper.Map<model1>(model2);
I have the services.AddAutoMapper(); at Startup.cs and my profile classes with Profile class inheritance.
I did the downgrade to 2.0.1 and it started to work fine again.
What changed? It's a bug or have new way to configure?
Hi, I'm using npm to install this after adding AutoMapper successfully. but I'm getting this error:
error: Package 'AutoMapper.Extensions.Microsoft.DependancyInjection' is incompatible with 'all' frameworks in project 'D:\angular\vega\Vega.csproj'.
I tried with different versions of both AutoMapper and AutoMapper.Extensions.Microsoft.DependancyInjection but no luck. what should I do?
