Load Only the Projects You Need with Solution Filters

https://devblogs.microsoft.com/visualstudio/load-only-the-projects-you-need-with-solution-filters/

While I don't have a hundreds of projects in a solution, our larger application definitely has a few that don't need to be loaded each time (test apps, etc).

It's a great feature but not very discoverable – I can see why they needed a blog post for it. Maybe the VS Team can come up with a better way.
