Your Output type is Class Library. You cannot start a class library, because it compiles to a dll, not an exe. It is intended to be used by other projects.

If you want to start that project, you should create a project of type like Console Application, or WPF Application.

Each project that can be started needs an entry point, for Console Applications this is typically a static main method in Program.cs, e.g.:

class Program
{
    static void Main(string[] args)
    {
    }
}
