When trying to debug a MVC 5 web application in Visual Studio 2012, it would tend to crush. If you put the build to release mode, then you could run the application but not debug it. This problem usually occurrs when you are using IIS7Â to host the site in the local development environment.
What could cause it is due to the fact that you have 7 worker process and several users logged into the site. When debugging the web application, Visual Studio has to attach it to the work process.
