Question

As soon as I switch

Answer 1

I have tried a lot of different solutions available in the web, but either they did not quite fit onto my problem, or they did not work.

To recap my problem:

After switching CompileViews on, I immediately got the above error during compile. I am using the default Visual Studio Development Server of VS2010 to test my MVC app.

Today I opened a request at Microsoft Developer support, and - I am almost ashamed to admit it - got my answer approximately 30 seconds into the callback from the technician:

All he said was: Please goto your obj folder and delete all contents. Then compile again.

And that really was all it took.

So after a lot of head-shaking about myself I wanted to share the results with you.
