Edited Issue: System.IO.FileLoadException in AttributeBasedFormatter.AllTypes [12476]

I don't know how to reproduce this in simple project, but I am getting this exception on a test project that uses StackExchange's MiniProfiler


```
Test(s) failed. System.IO.FileLoadException : Could not load file or assembly 'System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

IMHO, it would be Ok to handle FileLoadException the same way other exceptions are handled in GetExportedTypes.

Thanks.
