I have been using Visual Studio 2008 quite long but lately I am getting this message when I am developing an application in C#:
Common language runtime detected an invalid program
This happens when I try to enter to the properties of a component (text masked box properties, tool box property etc..). But it really became a problem when I tried to launch an other solution that I downloaded from the Developer's 5 star program of Microsoft and it didn't allowed me to launch at all and just got the same problem...
I looked for the answer at google but just got some clues about people having the same vague error but in different situations like in ASP.NET
I would appreciate any help with this issue... :( I do not want to reinstall VS, that will be my last resource...
Update:
I never figured out what the problem was so I installed a virtual machine with Windows XP on it, there I only have Visual Studio and Netbeans.
Can you reproduce the problem in a new solution without referencing any extra assemblies? If so, I think reinstalling would be your best bet. Sorry!
