I open the solution WinFormsCLR2.sln but when i try to run i got this message:
What can i do to resolve this problem?
Find the project that produces exe not dll, right click on it and select "run as startup project"
I didnt find the project with exe ...... its very bad
Right click on each project and select "Properties", then see what is the "Output Type". When you see a project that its output type is "Windows Application" or "Console Application", set this project as the startup project.
