"I assume your leader reflects your values"

MAGA: Actually, he is a twice-divorced serial adulterer and felon

"Then I assume he's brilliant"

MAGA: He's surprisingly dumb

"But he must be handsome"

Please go to Tools, Options, search for "cohost", turn it on, restart VS, and let me know how you go. You can submit feedback through VS, on GitHub (dotnet/razor), post or message here, on Reddit, I really don't care. Just let me know what issues you have so I can fix them. Thanks, I love you.

Hey so Visual Studio 2026 Insiders is out, and it's very exciting, but if you edit Razor files I have a personal favour to ask. For the last ~18 months I, and a few of my friends, have been working on a new foundation for the Razor editor called "Cohosting". I'd love for you to try it out.
