Debug Target Is Missing?

Question

When I try to build my solution, I get the following error:

Visual Studio cannot start debugging because the debug target \'c:\\target\' is missing. P

Answer 1

I had this error too (in VS2010), and in my case (two projects in one solution, with one being for unit tests) the answer was to go into the solution's (not the project's) properties and set a single startup project. I would've thought it also necessary, in that project's settings, under Application, to specify the "Startup Object", but it's working for me with or without that.
