Unable to start debugging on Web server

The application you are trying to debug uses a version of the Microsoft .NET Framework that is not supported by the debugger.
The debugger has made an incorrect assumption about the Microsoft .NET Framework version your application is going to use.
The Microsoft .NET Framework version specified by you for debugging is incorrect

I am getting this issue when i create my application directly in local host and running, works well if my application is in directory, so can any one tell what to do to resolve this issue

Solution 1

Make sure that all your dotnet versions are registered with IIS using the ASP.NET IIS Registration Tool[^]

Solution 2

As Marcus Kramer says, but also Also, check the 'ASP.NET version' configured against the Website. You'll find this under the ASP.NET tab of the Web Site Properties. It should be 2.0.50727 or 4.0.30319 but could well be incorrectly set to 1.1.4322 which would have this effect.

Also, have a look the

Error: Unable to Start Debugging on the Web Server[^]

entry on MSDN. It could save you a lot of time over trying one solution at a time and coming back to repost...
