I use the latest candidate for the release of EF v5 as for every announcement here . My model uses mapping files through EntityTypeConfiguration ...
When I tried to replace the string property on my enum model (drop + recreate db), I got this exception:
System.NotSupportedException was unhandled by user code Message=The enum or spatial property 'Category' on type 'Vehicle' cannot be mapped. Use DbModelBuilderVersion 'V5_0' or later to map enum or spatial properties.

My Controller is an ApiController, and the interrupt line looks like this:

By the way, I am using ASP.NET MVC 4 beta + Web API on VS 2010 (since .NET 4).
Any ideas?
