Where did IControllerTypeProvider go in RC2?

[dotnetjunkie]

In rc1, a call to AddMvc ensured the registration of an IControllerTypeProvider implementation. In rc2 however, no such registration is made and while browsing through the source code there seem to be no usage of IControllerTypeProvider (although the Github repository search might invalidly return not the right results).

Why is no IControllerTypeProvider registration made and what is currently the way to request a list of controller types from MVC?

IControllerTypeProvider and the surrounding infrastructure was replaced by application parts and features, specifically ControllerFeature. See https://github.com/aspnet/Mvc/blob/dev/src/Microsoft.AspNetCore.Mvc.Core/Internal/ControllerActionDescriptorProvider.cs#L96-L102 for usage.

Oddly IControllerTypeProvider continues to exist in the code base but isn't used anywhere. It needs to be deleted.

@pranavkm yeah let's remove IControllerTypeProvider.

#4735 < PR for it

[pranavkm]

@dotnetjunkie - I removed the type as part of 15f113d. Let me know if you have issues working with the ControllerFeature.

[javiercn]

@pranavkm is correct

[dotnetjunkie]

@pranavkm, using the example in the code base you postef at, I managed to get this working.

From an API perspective the creation of a feature onject and sending it to the part manager feels a bit weird though; there might be an abstraction or extension method missing, although admittingly a request for all controller types might not be a very common use case.
