When it comes to migration from MVC 4 to MVC 5 - I've done it, and it works. Maybe you've done some mistake during migration? I cannot verify it based on provided information.
Try to troubleshot that. Get some MVC 5 demo application, e.g. from Getting Started with ASP.NET MVC 5 (github link inside), and install EA. No such an error occurs.
(I assume you're not using ASP.NET Core since it is not supported yet.)
It is working now after I finished updating NuGet packages...most likely it was that EntityFramework needed to be updated to version 6 along with the MVC update.
Thank you.
Hello,
I upgraded my project from MVC4 to MVC5 and I now receive the following error in my global.asax on this line:
DataAnnotationsModelValidatorProvider.RegisterAdapter(typeof(RequiredIfAttribute), typeof(RequiredIfValidator));
"The type ExpressiveAnnotations.MvcUnobtrusive.Validators.RequiredIfValidator must derive from System.Web.Mvc.ModelValidator"
When I change the entry in the global.asax to the method recommended in release 2.5:
ModelValidatorProviders.Providers.Remove(ModelValidatorProviders.Providers.FirstOrDefault(x => x is DataAnnotationsModelValidatorProvider)); ModelValidatorProviders.Providers.Add(new ExpressiveAnnotationsModelValidatorProvider());
I receive this error:
"An exception of type 'System.ArrayTypeMismatchException' occurred in mscorlib.dll but was not handled in user code Additional information: Attempted to access an element as a type incompatible with the array."
Thanks,
Steve
