Error debugging in a MVC View: The following breakpoint cannot be set

Question

There's no real code example to show since it will happen no matter where you put the breakpoint.

Using Visual Studio 2013 (we migrated this project from 2012), I get this error when setting a breakpoint in any .cshtml View:

The following breakpoint cannot be set

I've tried various things such as cleaning my solution, closing and opening VS2013, and others. Nothing seems to work.

What can I do about this?

We found this node in our site's root Web.config:

<compilation debug="true" targetFramework="4.5" assemblyPostProcessorType="Microsoft.VisualStudio.Enterprise.Common.AspPerformanceInstrumenter, Microsoft.VisualStudio.Enterprise.AspNetHelper, Version=12.0.0.0, Culture=neutral, PublicKeyToken=xxxxxxxxxxxxxxxx"/>

Lo and behold, removing the assemblyPostProcessorType attribute solved the issue. It should look like this after the fix:

<compilation debug="true" targetFramework="4.5" />

Hope this helps somebody else. It was driving my boss crazy...
