title: Common Language Runtime detected an invalid program in Visual Studio
body: <p>I have been using Visual Studio 2008 quite long but lately I am getting this message when I am developing an application in C#:</p>
  
  <blockquote>
    <p>Common language runtime detected an invalid program</p>
  </blockquote>
  
  <p>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...</p>
  
  <p>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</p>
  
  <p>I would appreciate any help with this issue... :( I do not want to reinstall VS, that will be my last resource...</p>
  
  <p><strong>Update:</strong></p>
  
  <p>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.</p>
