c# - System.Diagnostics.Debugger.Debug() stopped working

Question

I'm working on a program which uses the System.Diagnostics.Debugger.Break() method to allow the user to set a breakpoint from the command-line. This has worked fine for many weeks now. However, when I was working on fixing a unit test today, I tried to use the debug switch from the command-line, and it didn't work.

Here's what I've tried:

• I've confirmed that the Debug() method is really being called (by putting a System.Console.WriteLine() after it)
• I've confirmed that the build is still in Debug
• I've done a clean build
• I've restarted Product Studio

A quick Google search didn't reveal anything, and the API documentation for .Net doesn't mention anything about this function not performing correctly. So... any ideas?

Answer 1

I finally figured out what was happening. For some reason, something changed on my machine so that just calling Debugger.Break wasn't sufficient anymore (still don't understand what changed). In any case, I can now cause the debugger to come up by using:

if (Debugger.IsAttached == false) Debugger.Launch();
