Big improvements to the performance of developing C# file-based incoming. Subsequent builds/runs will cache MSBuild outputs & directly invoke the C# compiler if inputs don't change. This in addition to the work in rc.1 to avoid MSBuild completely for simple file-based apps

Hey friends! I did a TEDx talk and it's now up on the TED Conferences YouTube. It's possibly the best and most important talk I've ever done.
I would ask that you watch it, and please SHARE it broadly and widely. Thank you! youtu.be/dVG8W-0p6vg #AI #Tech #TED

It is so neat seeing tech like this built on top of the dotnet run app.cs work that we're doing.

`dotnet run file.cs` is coming:
Allows running C# source files with no need for an explicit backing project. We call these file-based programs (as opposed to project-based programs).

You can always tell who's worked with me a long time by how they respond to my questions about insane situations:
Rookies: Here is why ... and by the way why are you asking that question?
Veterans: Here is why and I'm now leaving this chat so you can't tell me why you asked that question.

Building a Debugger is now officially released!
It guides you through building a whole native x64 debugger from scratch, dispelling all the magic and teaching you a ton about operating systems as it goes.
Even if you don't care about building a debugger, you can read it to your cat.

Trick I’ve been doing lately is getting AI to give me book recommendations. I just feed it all the books I’ve read, tell it why I liked a book and ask for ideas.

As your titles get bigger you need to be conscious about the potential for the things you say to be interpreted differently by the people around you. It is very easy for what used to be off hand comments / musings to start being interpreted as setting direction or defining goals.

Got a customer bug this week that only reproduces when the number of characters generated from razor / cshtml files is an exact multiple of 40K. One of the items in the generated files is the path of the file. Needless to say, that made the bug incredibly challenging to reproduce.
