Are you asking if the compilers can emit IL source code directly? If so then not that im aware of. But ildasm effectively gives you that capability. Its what even the compiler teams use to see the resulting IL

Reuse CSC arguments in file-based app runs by jjonescz Β· Pull Request #50635 Β· dotnet/sdk Part of #48011. This optimization saves CSC arguments when MSBuild runs and then reuses them in subsequent runs so dotnet run file.cs can skip MSBuild and invoke only the compiler. In my simple exp...

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).

null is a reserved keyword in C#. Been that way since 1.0.

There are over 145,000 uses of <LangVersion>latest</LangVersion> on GitHub alone. Whether or not it's a bad idea is somewhat irrelevant at this point because it's a popular one.
