Parser Error Message: Could not load type ‘_Default’

While developing a .Net web app in C# with Visual Studio 2005, I got this error:

Parser Error Message: Could not load type ‘_Default’

The reason: My website configuration was using the wrong .NET framework version (1.1.4322).

The solution: Change it to use a .NET 2.0 version. In my case, 2.0.50727

The result: a nicely displayed page :)

If you’re experiencing something similar, I hope this sheds some light ;)

    This problem comes when the project is in the higher framework version and the project is running in the lower framework version settings. Change the framework version settings from the properties in the Inet manager. and the n the page will execute.
