Q:

Cannot launch the debugger.  The required property 'LocalDebuggerWorkingDirectory' is missing or empty

I have the error I wrote in the title when I'm trying to launch the application.  I searched with google and I didn't find any page with 'LocalDebuggerWorkingDirectory' keyword.  The solution contains a mix of c# and c++ projects and it worked fine until today... I use Windows 7 and Visual Studio 2010.  Do you know where I can find this property to change it or how can I add it? 

A:

I can repro that, your startup project must be a C++ project.   Right-click it, Properties, Debugging, Working Directory setting.   Yours is empty.   The default is $(ProjectDir)
