Or vice versa.

When changing a column from a string to a Timespan, or Timespan to string, an exception of type

Caught unhandled InvalidOperationException
An OppositeColumn only exists on a OneToOne relationship

is thrown. Should probably be something else.

I wasn't able to register the Mysql Data Provider whose config had been updated in the app.config of my project registered in PathToDll. Instead, I had to copy it to the DbProviderFactories section in the machine.config.

Would prefer to have a .config file that is used by dbm without a dependency to machine.config.

I have several base entities, all with similar stuctures, which all inherit from an interface. When querying a parent object, the interface type is used rather than the concrete type.

e.g.
ApplyTagsSearch<TEntity, TTag>(this ISelectQuery<TEntity> query) where TEntity : class, IHasTags<TTag, TEntity>, new() where TTag : IIAmTag<TEntity> { query.Where(o => o.Tags.Any(ot => tags.Contains(ot.Tag.TagId))); }
tags is an int[] of tag IDs

The exception thrown by Dashing is "Type IIAmTag`1 is not mapped"

class Entity {
    public OtherEntity OtherEntity { get; set; }
}

to

class Entity {
    public AnotherEntity OtherEntity { get; set; }
}

doesn't get spotted by dbm as a change to the foreign key

query.Where(s => s.StartDate <= DateTime.UtcNow.Date);

throws a null reference exception where

var today = DateTime.UtcNow.Date; query.Where(s => s.StartDate <= today);

Does not.

Do you have plans to migrate Dashing to netstandard2.0 and newer versions of .net core such as 2.1 and 3.1?

Currently, .Any() is supported on enumerables within the query - e.g. .Where(customer => customer.Orders.Any(o => o == order)). It would be useful to be able to use .Any() on enumerables which have been declared in the calling scope - e.g. .Where(customer => ordersOutsideQuery.Any(o => o.Customer.Name.StartsWith(customer.Name)))

In InMemoryEngine the Save will return the number of entities that already exist and updates them where necessary. In SQLEngine the Save will return the number of entities to be updated. In the case where the item exists but doesn't need to be updated InMemoryEngine returns 1 and SQLEngine returns 0. The 0 returned from SQLEngine then prompts the Insert.

Save() return values:

                 | Exists no change | Exists change needed | Does not exist
InMemoryEngine   |       1          |           1          |         0
SQLEngine        |       0          |           1          |         0

Save() != Exists() in SQLEngine is there a better method to check whether something already exists in InsertOrUpdate() or should Save() change so that is is synonymous with exists.

Either way InMemoryEngine and SQLEngine should give the same results.

If there is one or more entities without a primary key then the rest of the entities break on tracking:

Initialization method Dashing.Repository.Tests.CRUDTests.Test_Initialize threw exception. System.InvalidCastException: System.InvalidCastException: Unable to cast object of type 'Dashing.Model.Product' to type 'Dashing.CodeGeneration.ITrackedEntity'..

To reproduce add this class to TestDomain:

public class NoPrimary {
    public virtual string Name { get; set; }
}
