title: What is the equivalent of System.Diagnostics.Debugger.Launch() in unmanaged code?
body: <p>I need to launch a debugger from my native C++ program when certain conditions are met. In C# I just call System.Diagnostics.Debugger.Launch(). I thought that Win32 DebugBreak() call will do what I want, but it just terminates the application if there is no debugger present.</p>
  
  <p>How do I launch a new instance of the debugger (the famous "Possible debuggers" dialog) from native code? Is it even possible? I could try to use COM to create a new instance of Visual Studio, but it is kinda complicated, and will also lock me to a particular version of VS.</p>
