CLR - Common language runtime detected an invalid program in VS.NET

Question

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...

Thanks.

Answer 1

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!

Answer 2

I never figured out what the problem was... so turning around... I installed a virtual machine with Windows XP on it, there I only have Visual Studio and Netbeans.. Damm! it is really fast :)

Thx for the time

Answer 3

A colleague of mine had a problem where his toolbox ended up corrupt. Try opening the toolbox, right-click, and choose 'Reset Toolbox'. You never know.

Answer 4

I never did find a solution for this issue online. But what fixed it for me, was to use the 'Clean Solution' option in Visual Studio.

Seems VS had gotten a little 'dirty', somehow.

Answer 5

Clean Solution worked for me too. I'd definitely try this before going through Microsoft's troubleshooting guide.

Answer 6

Thx guys, the "Clean Solution" did it for me!!! Cheers.

Answer 7

Clean solution does not work for me :(
