I used to be able to build and run my console applications by hitting Ctrl + F5 in visual studio. This no longer works. I looked everywhere. Does anyon

Answer 1

It happend to me something similar, but only with one project, and the others running right with CTRL + F5, so i will post here my problem and solution because it could help people searching for the same problem, as i was :)

I was opening in Visual Studio 2012 a solution created with Visual Studio 2013, and it didn't run with CTRL + F5. I open the solution file with notepad, and i change the following section:

GlobalSection(SolutionConfigurationPlatforms) = preSolution
    Debug|Any CPU = Debug|Any CPU
    Release|Any CPU = Release|Any CPU
EndGlobalSection

with this other:

GlobalSection(SolutionConfigurationPlatforms) = preSolution
    Debug_x86|Any CPU = Debug_x86|Any CPU
    Debug_x86|x86 = Debug_x86|x86
    Debug|Any CPU = Debug|Any CPU
    Debug|x86 = Debug|x86
    PruebaRelease|Any CPU = PruebaRelease|Any CPU
    PruebaRelease|x86 = PruebaRelease|x86
    Release|Any CPU = Release|Any CPU
    Release|x86 = Release|x86
EndGlobalSection

That solves the problem for me.
