Cannot consume scoped service IGenericProcessorFactory from singleton IOperationProcessorResolver

Attempted to update from version 2.2.3 to the latest stable 2.3.3

As a consequence had to update Microsoft.EntityFrameworkCore.SqlServer and Microsoft.EntityFrameworkCore.Tools from 2.0.3 to 2.1.1

After that operations stopped working with the following error message:

}

Upon investigation I found out that updating either Microsoft.EntityFrameworkCore.SqlServer or Microsoft.EntityFrameworkCore.Tools to version 2.1.0+ brakes the operations - no matter the version of JAPDNC.

The dependency to SqlServer comes from this line in my startup:
services.AddDbContext<DomainDbContext>(options => options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")), ServiceLifetime.Transient);

If you’re using operations, I highly recommend upgrading all the way to 2.4.0-beta1.

We are currently dogfooding this release which is why it is in beta but it has some essential fixes.
It would also be really helpful to get feedback from someone else using operations.

@jaredcnance I also tried updating to the beta release - the error persists.

Btw, I find the operations feature extremely useful, so I really do hope that this feature won't get dumped :)

Operations are a high priority for us and are definitely not getting dumped 😄. I don't believe the error is actually related to the version of the SqlServer provider but the lib itself. It looks like it is caused by overwriting the service registration for IGenericProcessorFactory:

JsonApiDotNetCore/src/JsonApiDotNetCore/Extensions/IServiceCollectionExtensions.cs

Line 163 in 404231b

services.AddSingleton<IGenericProcessorFactory, GenericProcessorFactory>();

JsonApiDotNetCore/src/JsonApiDotNetCore/Extensions/IServiceCollectionExtensions.cs

Line 138 in 404231b

services.AddScoped<IGenericProcessorFactory, GenericProcessorFactory>();

But really I think IOperationProcessorResolver and IGenericProcessorFactory should be scoped registrations. I'm not sure why this hasn't been caught in tests. I'll look into it further this afternoon, but you might be able to do something like this as quick fix:

services.AddJsonApi();
services.AddScoped<IOperationProcessorResolver, OperationProcessorResolver>();

This does indeed fix the issue.

This issue actually might have originated a long time ago, since I did this in an old service, although from what I can remember only for debugging purposes.

This has been fixed in v2.4.0-beta2.
