I have a sample which I was able to run in VS2003 but running the same sample in VS2005(v 8.0.50727.42) giving me debugg error.

Unable to start debugging. Iam getting the error message as given below.

1. The application you are trying to debug uses a version of the Microsoft .NET Framework that is not supposed by the debugger.

2. The debugger has made an incorrect assumption about the Microsoft .NET Framework version your application is going to use.

3. The Microsoft .NET Framework version specified by you for debugging is incorrect.

For solving this issue I did

In the Registry Editor, open the HKEY_LOCAL_MACHINE folder.

Navigate to: HKEY_LOCAL_MACHINE\Software\Microsoft\VisualStudio \8.0\AD7Metrics\Engine\{449EC4CC-30D2-4032-9256-EE18EB41B62B}

then created new string "CLRVersionForDebugging" and value "V2.0.50727" . After doing all this things still Iam getting the same debug error.

Pls anybody can give solution for this problem.

Hi there,

Is this a ASP.NET application you're trying to run?

Also, did you run through the upgrade wizard when you opened the solution?

Thanks
Andrew
