:scroll: Visual Studio extension to generate OpenAPI (Swagger) web service reference.

Unchase OpenAPI (Swagger) Connected Service is a Visual Studio 2017/2019/2022 extension to generate C# (TypeScript) HttpClient (or C# Controllers) code for OpenAPI (formerly Swagger API) web service with NSwag.

Starting from Visual Studio Community 2019 v16.1.3 extensions based on Microsoft Connected Services now work fine.

The project is developed and maintained by Nikolay Chebotov (Unchase).

• Command to compare .nswag.json specification file with another .nswag.json specification file (or specification given by endpoint)
• Storage of the last 10 endpoints (specification path)

Settings Meaning

Meaning of the Unchase OpenAPI (Swagger) Connected Service settings according to NSwagStudio:

Exclude type names

Since v1.4.0 you can exclude type names in separate Window for C# client code generation:

Generate code from OData specification converted to OpenAPI specification

Since v1.5.0 you can generate code from OData specification converted to OpenAPI specification:

Custom Commands

Open in NSwagStudio Command

Since v1.1.* have been added menu command embedded in Visual Studio Solution Explorer context menu lets you open generated .nswag and .nswag.json files in NSwagStudio.

This extension is for those times where you generate .nswag and .nswag.json files and you want to be able to quickly open it in NSwagStudio.

Prerequisite

In order to use this extension, you must have Visual Studio 2017/2019, this connected service as well as NSwagStudio installed.

Solution Explorer

You can open .nswag and .nswag.json files in NSWagStudio by simply right-clicking it in Solution Explorer and select Open in NSwagStudio:

Path to NSwagStudio.exe

If you installed NSwagStudio at a non-default location, a prompt will ask for the path to NSwagStudio.exe.

You can always change the location in Tools -> Options -> Web -> Unchase OpenAPI (Swagger) Connected Service:

Compare OpenAPI-specifications... Command

Since v1.2.* have been added menu command embedded in Visual Studio Solution Explorer context menu lets you compare generated .nswag.json specification-file with another .nswag.json specification-file (or with specification given by endpoint).

This extension is for those times where you generate .nswag.json file and you want to quickly compare it with another specification or specification given by endpoint.

Prerequisite

In order to use this extension, you must have Visual Studio 2017/2019 as well as this connected service.

Solution Explorer

You can compare .nswag.json specification-file with another .nswag.json specification-file (or with specification given by endpoint) by simply selecting one or two files and right-clicking them in Solution Explorer and select Compare OpenAPI-specifications...:

Path to the specification Endpoint

You can always change the specification Endpoint to compare with in Tools -> Options -> Web -> Unchase OpenAPI (Swagger) Connected Service:

• ... request for HowTo you need

Troubleshooting

Can't open .nswag file in NSwagStudio

• You can use Open in NSwagStudio menu command
• If generated code corrupted, try to open .nswag file in NSwagStudio (Windows GUI for editing .*nswag files)
• If it doesn't open, try to create new .nswag file in NSwagStudio for the same API service link and check the differences

Installation completes but I can't see the Service in the list of connected services (Visual Studio 2019)

• Relevant bug report. Connected Services restored in the v16.1.3 update to Visual Studio 2019.

unchase.openapi.connectedservice's Issues

Incorrect generated method names

Generated method names contain endpoint name and request type e.g. PostersGetAsync, while client generated with built-in tool creates names according to description (parameter operationId) e.g. GeneratePosterRequestAsync

Visual Studio 2022 Support

Installed product versions

Visual Studio: 2022 All Versions

Description

Make the extension available in Visual Studio 2022.

Steps to recreate

1. Download the extension installer.
2. Run the installer.

Current behaviour

The message that it is already installed to all applicable products appears even though it is not installed in Visual Studio 2022.
It is also not listed in Online Extensions in Manage Extensions Visual Studio 2022.

Expected behaviour

Installs and works in Visual Studio 2022.

Note: Sorry for all the extra details. I probably could have stopped with the title on this one.

BUG: Could not load file or assembly 'YamlDotNet, Version=5.0.0.0' when trying to generate code

Describe the bug

When I try to use the Unchase Connected Service Tool v1.4.7 to generate client and/or controller code from a YAML file, I get an error referencing YamlDotNet. I have the problem whether trying to generate the code for the first time, or if trying to update the connected service. Manually adding YamlDotNet version 5.0.0 to the project did not resolve the problem.

Use this public YAML to generate against: https://raw.githubusercontent.com/OAI/OpenAPI-Specification/master/examples/v3.0/petstore.yaml

Assemblies affected

YamlDotNet.

Steps to reproduce

The simplest set of steps to reproduce the issue. If possible, reference a commit that demonstrates the issue:

1. Open a Visual Studio Solution.
2. Within the Connected Services section, right click on the service and select "Updated Unchase OpenAPI..." from the context menu which appears.
3. Generate for https://raw.githubusercontent.com/OAI/OpenAPI-Specification/master/examples/v3.0/petstore.yaml
4. Choose to generate both Client and Controller code.
5. Select Finish.
6. Select "Yes" if prompted to replace the .nswag file.

Expected result

C# code should be generated.

Actual result

No C# code is generated. From the Output window:

Microsoft.CodeAnalysis package not deploy with extension package

I installed the latest version of the extension and an error started saying that I can't find the Microsoft.CodeAnalysis package when I'm generating the CSharp client.

In order to use the version I had to copy the DLL (Microsoft.CodeAnalysis, 3.4.0) to the extension installation folder.

Could you put the DLL as part of the package in the next version?
Thanks

Unable to read string as a response

Hi,
I am unable to read the string response, as it always tries to deserialize the response. is there any way to read the string, int without deserialization?

}



CLIENT CODE

-> MailData Class did not exist
 private MailData data= new MailData(); 

My problem here is that i can't instantiate an object from type MailData in my client code.
Can't find the MailData class in the generated code.

How can i solve this issue?

Updating / Regenerating a service client causes error in Visual Studio

If you try to update a previously added connected service (OpenAPI C# client) an error happens and Visual Studio shows a message box. The connected service is also not updated.

BUG Fixes : Need modification in generated serializer

Hi,

I had an issue of including subclasses using swagger and I have resolved it by introducing the $type variable upon which JsonInheritanceConverter class is generated but my other methods which include child class stopped working. The exception was thrown on the below line as code was unable to find discriminator value in child class.

var discriminator = Newtonsoft.Json.Linq.Extensions.Value<string>(jObject.GetValue(_discriminator));

To resolve this i have modified the generated code manually by replacing the above line with

var discriminator = "";
if (jObject.TryGetValue(_discriminator, out var jToken))
{
discriminator = Newtonsoft.Json.Linq.Extensions.Value<string>(jToken);
}
So it would be great if you can modify the extension so it will be code safe for the child classes.

BUG

Visual Studio 2019 16.9.4

Using the OpenAPI file https://github.com/bigcommerce/api-specs/blob/master/reference/catalog.v3.yml
with Unchase to generate a C# client creates methods with bad parameters.

i.e.
CatalogProductsGetAsync(id, id:in, id:not_in, id:min, id:max, id:greater, id:less, etc....

Use relative specification file path not working as expected

Describe the bug

I select "use relative specification file path" and only leave the file name of my specification.yaml in the "will combine with:" edit field. When I click finish and inspect the generated files, the "Endpoint" setting in the "ConnectedService.json" contains the full path to the specification. When you then run the wizard again through "Update Unchase OpenAPI (Swagger) Connected Service...", the "will combine with:" edit field now contains the full path as well.

Assemblies affected

Unchase OpenAPI (Swagger) Connected Service 1.5.8

Expected result

I would expect the full path to be constructed at run-time using the project directory and the path to the specification file, relative to it, so that the project can be used independently from it's location (and shared between devs).

Actual result

The full path to the specification.yaml file is saved inside "ConnectedService.json" and as soon as you rename the solution folder, or move the solution folder to a different location, the next time you start the wizard, it fails.

Route Template

is here a way to template a routing

api/blahblah/{controller}/blahblah/{action}

Error: Cannot populate JSON array onto ype 'NJsonSchema.JsonSchemaProperty'

And the client doesn't generate.

Assemblies affected

Which assemblies and versions are known to be affected?

Steps to reproduce

The simplest set of steps to reproduce the issue. If possible, reference a commit that demonstrates the issue:

1. Create a new VS project
2. Try adding a connected service of the attached file
3. See error

Expected result

I cannot generate code from file with size 528kb

I trying to generate client code for open api json file with size 528kb and it does not work, but, when i try with another file with size 115kb, that file works. Is it possible to fix this?

Question: Is there a way to re-generate from ConnectedService.json

Hi,

This service is great!

I however, don't understand what the ConnectedService.json is supposed to do if there is no way to re-generate the classes from it?
I can modify MyClient.nswag and open it in nswag studio, and that works, but what is the ConnectedService.json for then?

My gut feeling is that I'm just missing something and I can't seem to find a setting/button for this.

Dave

After update on v1.5.19 from v1.5.17 cannot serialized object.

Incorrect `DisallowNull`

Describe the bug

swagger.json describes an optional parameter but a DisallowNull tag is generated for it.

Assemblies affected

Generated using the NSwag toolchain v13.6.1.0 (NJsonSchema v10.1.21.0 (Newtonsoft.Json v12.0.0.2))

Steps to reproduce

My class looks like this:

public abstract class Option
{
    protected Option(string? error)
    {
        this.Error = error;
        this.HasFailed = error != null;
    }

    public string? Error { get; }

    public bool HasFailed { get; }
}

public sealed class Option<T> : Option
    where T : class
{
    public Option(T? value, string? error)
    : base(error)
    {
        this.Value = value;
    }

    public T? Value { get; set; }
}

When I use this class, like Option<AccountDto>, it generates this json:

"AccountDtoOption":{
  "type":"object",
  "properties":{
	 "value":{
		"$ref":"#/components/schemas/AccountDto"
	 },
	 "error":{
		"type":"string",
		"nullable":true
	 },
	 "hasFailed":{
		"type":"boolean"
	 }
  },
  "additionalProperties":false
}

Which generates the following model in the client:

[System.CodeDom.Compiler.GeneratedCode("NJsonSchema", "10.1.21.0 (Newtonsoft.Json v12.0.0.2)")]
public partial class AccountDtoOption 
{
    [Newtonsoft.Json.JsonProperty("value", Required = Newtonsoft.Json.Required.DisallowNull, NullValueHandling = Newtonsoft.Json.NullValueHandling.Ignore)]
    public AccountDto? Value { get; set; }

    [Newtonsoft.Json.JsonProperty("error", Required = Newtonsoft.Json.Required.Default, NullValueHandling = Newtonsoft.Json.NullValueHandling.Ignore)]
    public string? Error { get; set; }

    [Newtonsoft.Json.JsonProperty("hasFailed", Required = Newtonsoft.Json.Required.Always)]
    public bool HasFailed { get; set; }
}

Expected result

I expect the generated JsonPropertyattribute for the Value property to have its Requred property set to AllowNull. It even adds a nullable sign (?) to the Value property.

Error during Client Proxy generation

Hey,

my openapi.json file openapi.zip for a MicroStrategy REST API seems to be invalid. The code generation fails with following error:

Error: Error while rendering Liquid template CSharp/Client.Class:
System.Reflection.TargetInvocationException: Ein Aufrufziel hat einen Ausnahmefehler verursacht. ---> System.NullReferenceException: Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt.
bei NSwag.CodeGeneration.Models.OperationModelBase`2.get_UnwrappedResultType()

Do you have any idea why this happens? Exists a method for enabling verbose log mode in NSwag? Thx a lot.

Thomas

VS 2019 OpenAPI code generator same as Unchase?

Hi, im using the latest version of VS 2019 and have added a swagger service reference in Connected Services.

Im trying to get the generated httpclient to include a custom type (converted from string (example: BigInteger)). How can this be done using Unchase and is it the same way when using VS Connected Services directly?

Hope you can help.

The configuration wizard should not require a .json extension

There's a good number of swagger endpoints online which expose the swagger doc using an endpoint which does not have .json extension in the URL.

Currently it's impossible to generate code for such documents.

The Compiler complains that ToString takes 2 arguments for x_message_timestamp

x_message_timestamp is delcared as System.DateTimeOffset?

If I change the code to use GetValueOrDefault() it works, which I will use for now as workaround.

if (x_message_timestamp != null)
if (x_message_timestamp != null)
                        request_.Headers.TryAddWithoutValidation("x-message-timestamp", System.Uri.EscapeDataString(x_message_timestamp.GetValueOrDefault().ToString("s", System.Globalization.CultureInfo.InvariantCulture)));

And how can i use the Api in my Code? I can't access to the functions.
Did you have a working sample project?

Thank you

How do I add http header attributes and values using the generated web api client

Hello There, I need your help/advice. I have installed Connected Service tool on Visual Studio 2019 and followed your instructions to generate web Api client.

I was able generate the client successfully and was able to invoke the endpoint methods.

Now I have to pass HTTP headers to the end point, how can I set the values for each Header property without altering the generated code.

Thank you

Error trying to update the connected service

When trying to execute Update Unchase OpenAPI (Swagger) Connected Service... on a connected service, which was generated with an older version, I get the following error:

When I set the OpenApiConvertSettings->PathPrefix to "OData" in ConnectedService.json and save the file, the above command works and the Wizard displays correctly.

My Version: 1.5.26

Feature Request: Allow Relative Path for swagger.json file

Basically, the tooling currently supports a URI or a file.
The URI is great in most cases, however in our use-case, the URI cannot be reached (due to network restrictions / proxy).

Therefore a file based approach works, however a full relative path is used instead of a relative path to the project (such that the swagger.json can be checked in and updated as required in the future but linked form the source repository rather than a full file path)

Hopefully I was clear enough in my explanation. Thank you

Updating / Regenerating a service client causes error in Visual Studio

Describe the bug

If you try to update a previously added connected service (OpenAPI C# client) an error happens and Visual Studio shows a message box. The connected service is also not updated.

The error message is:

Connected Services

The Connected Services component 'Unchase OpenAPI 
(Swagger) Connected Service' failed: (HRESULT:0x80131500) 
Error setting value to 'PathPrefix' on 
'Microsoft.OpenApi.OData.OpenApiConvertSettings'.

Assemblies affected

v1.5.13

Steps to reproduce

1. Open a project with an existing OpenAPI C# client
2. Click on 'Connected Services'
3. Right-click on the 'client folder'
4. Click 'Update Unchase OpenAPI (Swagger) Connected Service...'
5. Error happens - Message box is shown

Expected result

The C# client is updated to the current state as specified by the API URI

Actual result

An error message is shown. Otherwise nothing happens

Additional detail

The likely cause is the recent dependency update of Microsoft.OpenApi.OData to v1.0.6
As v1.0.6 contains the following commit Add Path provider and path prefix provider into setting

Now PathPrefix being null or the empty string is blocked in OpenApiConvertSettings.cs

The ConnectedService.json generated by this extension - which is loaded when you want to update the c# client - contains "PathPrefix": null, which causes the described error.

If you manually change the content to e.g. "PathPrefix": "/", you can update the c# client once but afterwards PathPrefix is again set to null

<Not edit Unchase OpenAPI (Swagger) Connected Service>

The Connected Services component 'Unchase OpenAPI (Swagger) Connected Service' failed: (HRESULT:0x80131500) Error setting value to 'PathPrefix' on 'Microsoft.OpenApi.OData.OpenApiConvertSettings'.

The Extension doesn't restore the previous settings for a client update.

The Extension doesn't restore the previous settings for a client update. I have to re-enter settings like the base class every time. I would also be very nice, if you could just right-click the json file to update the client.

Other than that, it is a real time saver. Thank you so much.

Compilation error generating C# client. Not all code paths return a value.

An invalid method has been generated.
The method has a code path which does not return anything.
As far as I can see it seems to only affect methods which have a return type of System.Collections.Generic.ICollection<long> in my project. Other simular methods return default(sometype), except for the type stated before.

The json used to generate the client can be downloaded from the file attached to this issue.

Impossible to add multiple connected services?

I want to add multiple services (multiple swagger docs), however when I click on the service reference I get a pop-up to update the existing service:

Is there a way to add a second one?

generation works fine. But thats not the goal of the definition.

Is it a bug or have i done something wrong in the definition?

Need options with "name" and replacing node name

Using this part

        "review" : {
          "type" : "array",
          "xml" : {
            "name" : "reviews",
            "wrapped" : true
          },
          "items" : {
            "$ref" : "#/definitions/BlaBla"
          }
        }

will generate field with name review and attribute

[Newtonsoft.Json.JsonProperty("**review**" ,...)]
public System.Collections.Generic.IEnumerable review{ get; set; }

It will be nice that if another options will exists like

• using name value for attribute name
• using name value for property name
• using name value for attribute and property name

[Newtonsoft.Json.JsonProperty("**reviews**" ,...)]
public System.Collections.Generic.IEnumerable review{ get; set; }

Split generated classes and interfaces into dedicated files

Hi,
first of all nice work!

Is it possible to split the generated file (now containing all interfaces/classes) into separate files? That is, Each class into one file and each interface into one file?

Case Sensitive file system prevents detection of configured specification endpoints

I have two versions of the same repository on my PC - one is set up within a folder that has case sensitivity activated and was created by git in WSL2.
The other was cloned within a folder with deactivated case sensitivity (the windows default) using git for windows in a powershell.

Within the windows variety, I can right click on a previously configured specification endpoint and I get the context-menu entry Update Unchase OpenApi….
In the other one this menu point never appears and I can only create new endpoints. Double clicking Connected Services shows a green check mark and the word Configured, for the case insensitive version, but nothing if the file system is case sensitive.

As .Net 5 moves to be compatible with other operating systems and development for .Net is not windows exclusive any more, it would be cool if this tool could handle file names in a case sensitive way.

Compatibility

When using Autowrapper (https://github.com/proudmonkey/AutoWrapper) on service, the json comes back with additional fields that do not show in swagger json that wraps the response object.

So when the connected service builds, it builds for the response object but not the wrapper put on by Autowrapper. Has anyone experienced this or found a quick workaround? I am trying not to modify the generated class.

thanks,
Greg

Generate an interface as well as the concrete client class

As above to enable DI and easier unit testing

Updating connected service on build

Is it possible to update the connected service on build (and optionally force through any notification messages)? My use case is a client library which generates from an endpoint on build.

Virus in TrendMicro detection

I installed the extension and when I publish my code, TrendMicro is saying the backdoor trojans are embedded in exe file and a script runs to try to turn off my system restore.

Feature: C# Client dialog reads in properties from previously generated Client.nswag

When updating a client, every setting, option, selection has to be documented in order to reproduce the OpenAPI client consistently. It would be a nice feature to not have to remember/document these settings but instead use (or ask to use) a previously generated nswag file generated by this connected service.

Can't generate Client or Controller

I am getting this error whenever I am trying to generate a Client
