Improve MVC endpoint detection

[DenisPav]

Hi, I've decided to try out your package due to older one from FluentValidation being deprecated. But I've bumped into a issue where none of my validators were actually fired. I've debugged everything and noted that the IAsyncFilter that you use to wire things up is detecting the MVC endpoints based of if controller is actually ControllerBase.

My current project is using a bit of a different MVC setup where controllers are not inherited but make use of ApiController attribute and conventions as described here.

Due to that validators won't get triggered as controllers are convention based and do not inherit ControllerBase or other controller based classes that are provided out of the box.

It would be great if we can somehow support this so that this flavor of MVC controllers will trigger validators automatically also.

PS: thanks for awesome project.

Hi @DenisPav, your MVC setup sounds like a use case we should support. I don’t have a lot of time on my hands at the moment so this one is going to have to wait unfortunately. Feel free to open up a PR if you are comfortable enough.
