Where are the settings for multiple startup projects on a solution stored?

Question

I've got a Visual Studio solution containing a couple of console app projects, and used the solution property pages to launch both of them when debugging. For some reason, this setting isn't saved in source control so when I check out the solution on a different computer it has to be set up over again.

Where is this info stored and how can I add it to version control?

I believe it is in the Visual Studio User Solution User Options file *.suo. This file is hidden by default. Most source control providers ignore this file by default because it stores location specific paths.

What else is stored in *.suo? Why isn't it normally added to version control? – Luke Mar 05 '10 at 06:05
Because (1) it is specific to you, and (2) it changes all the time. – Mitch Wheat Mar 05 '10 at 06:06

Check my update, here is another SO post on it. http://stackoverflow.com/questions/694730/why-is-set-as-startup-option-stored-in-the-sou-file-and-not-the-sln-file – Dustin Laine Mar 05 '10 at 06:07

I have to admit, that it does seem like startup projects would be in the solution file... – Mitch Wheat Mar 05 '10 at 06:07
Ah hmm..maybe I will just make one project launch the other and vice versa :) its mostly a demo anyway – Luke Mar 05 '10 at 06:09
I could see both angles, but working in large teams I understand where this would be problematic. – Dustin Laine Mar 05 '10 at 06:10

You can install the SwitchStartupProject extension. This will create a file called YourSolution.startup.suo containing the startup projects, which you can check into source control.

See also their wiki for configuration instructions and other info.
