The compiler failed with error code -1073741502 (SharePoint 2010 SP1 running on Windows Server 2008 R2)

Question

I have a virtual machine (running in VMWare Workstation 8.0.2 on my laptop) running Windows Server 2008 R2 Standard and SharePoint Server 2010 SP1 that I use for SharePoint development (Visual Studio 2010 is installed on the virtual machine). Sometimes I get the following error message:

Server Error in '/' Application.

The error is thrown quite randomly, sometimes when I activate a new feature, sometimes when I'm just browsing pages/lists in SharePoint. I have of course googled the problem, and I've found some solutions to it that have worked for some other users (but not for all):

• Do an iisreset (doesn't work for me)
• Do an iisreset, then reboot (doesn't work for me)
• Remove ASP.NET temporary files (doesn't work for me)
• Remove ASP.NET temporary files and reboot (doesn't work for me)
• Reinstall (repair) .NET framework (the only solution that works for me)

Does anyone have an idea of a solution that fixes the problem without repairing .NET framework? It's quite time consuming, not to mention frustrating to have to do this all the time. The error occurs anywhere between three to ten times a day.
