I'm getting the following error in VS when I save my cshtml helpers. The generated file is deleted also.
```
Error 2 Custom tool error: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.
```
I've recently moved to VS2012, and this is the first time I have edited my helpers since. Any ideas?
Comments: I have the same problem. Loader exception: Could not load file or assembly 'System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.":"System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35 Project has reference to System.Web.Mvc Version 4.0.0 In release notes I see: Version 1.5 of the VSIX adds support for Razor 2.0 syntax. It auto detects whether it should use 1.0 or 2.0 based on the assembly being referenced by the project. But by some reason it tries to load 3.0 that I don't have
