I’m having problems with one of my projects in VS2010 Pro, it won’t allow me to hit the “debug” play button at the top of the screen, it’s been disabled, when I open other projects or start new ones it’s enabled on the new project / other project, however, it’s disabled on the one project, I don’t know what I changed (it’s been awhile since I opened this as it pissed me off last time I opened it), what can I do to re-enable the “play” button? (debug), this is a Windows Phone 7 project and I was messing with the .csproj code.
Edit:
The menu-items have been disabled “Start Debugging: F5” doesn’t work, as well.
Thank you.
Make sure you do not have Multiple Startup Projects enabled per this MSDN Forum Link
