I'm writing a distributed app and testing requires that I run more than one instance at a time.
Is it possible to debug two or more distinct instances of the same project (at the simplest, passing in different command-line options)?

Can't you just attach the debugger to multiple instances? Debug -> Attach – Charleh Nov 14 '12 at 14:55

Yes, but that's pretty cumbersome. Was wondering if there's an slicker way. – spender Nov 14 '12 at 14:57

@spender How slick do you need it to be? – default Nov 14 '12 at 15:14

Yes, attach to both processes (Debug -> Attach to Process). They will appear under the Processes debug window and their threads will be grouped/headed by process in the Threads window.

Any way to make this less cumbersome? That's quite some number of clicks. – spender Nov 14 '12 at 14:56

1You could bind a shortcut key to Attach to Process, or put a `Debugger.Launch` call at the start of the process, it will prompt you to attach – Kieren Johnstone Nov 14 '12 at 14:57

See also Manuel's answer here, you may be able to write a macro like this one: http://stackoverflow.com/questions/9030071/visual-studio-2010-automatic-attach-to-process – Kieren Johnstone Nov 14 '12 at 14:58

Now we're talking. `Debugger.Launch` looks good. Didn't know about that. Thanks. – spender Nov 14 '12 at 14:58

I think I'll add a compilation symbol in a new project configuration and call `Debugger.Launch` wrapped in `#if`/`#endif`. That will work nicely for me. Thanks again. – spender Nov 14 '12 at 15:03
