• Check that the Standard toolbar shows that you are working in Debug mode. This is the most common cause for this problem. This setting controls what mode the Run will use. (Too see this toolbar, right click in the Visual Studio menu area and make sure the 'Standard' toolbar is checked.)
• Check that you are not running with ctrl+f5 (which equals Start Without Debugging). This does not match the error message you get, so likely not the answer.
• Check that the Solution Configuration does not specify that the project should be built in Release mode. To access this, right click the solution, see properties for the solution and then review the configuration settings for your projects in the configuration dialog editor that pops up.

you're trying to debug your project in Release mode... Switch the project into Debug mode, click Rebuild and then press F5.
