I am not able to debug after converting a project to older version

Hi,

I just converted the VS2012 C# Class library to VS2008 compatible. It converted successfully and do not get any error while building the project and getting successful build. While trying to debug the particular project I am getting “Debugger not compatible message” as attached screenshot.

I set the project as Startup and pressing F5 to debug but could not debug. It is a Console project.

Error Message: Error while trying to run the project: Unable to start debugging.

Please assist me the how to debug the application.

Thanks
