Server side validation with custom DataAnnotationsModelValidatorProvider

Question

I have setup a custom provider to allow setting validation attributes from a data store instead of in static code. Works great with the client side validation in my .NET MV

Answer 1

I finally figured this out, it's a pretty simple answer. The ApiControllers only respond to the providers in the System.Web.Http.Validation namespace, not the System.Web.Mvc namespace that is used for regular Controllers and the client side validation.

I implemented both to achieve both the client side validation and server validation in the ApiControllers.
