Happy Birthday Visual Studio Tip of the Day!  Wow, what a difference a post a day makes.  Thanks to everyone who has been reading the series.  It’s been an extremely rewarding experience to see these tips help.

  • Multiple startup projects – and there was great joy.  When enabled, you can then pick and choose which projects to start (and make sure you choose Start and not Start without debugging)


And using the example above, when I hit F5, I get
