Visual Studio options greyed out?

I'm working on a ASP.NET Web Application project, and I'm unable to add a web form to application. The "Add Item" menu item isn't there like it was before. I've tried three d开发者_JAVA百科ifferent projects and it keeps happening each time. You can see what I'm referring to below:

Turns out I was in the middle of a debug (thanks Brad Christie) so if anyone has that problem, that's the likely solution.

Publish option greyed out

For me, the project I was trying to publish needed to be selected in the project explorer before the publish option became available.

Why put this answer here?

Google sent me here even though I was specifically searching for the Publish option. If it sends other developers here, perhaps this answer may be useful.
