That's not quite true. We use Arcade for Interactive Window repo as well.

This repo is using RepoToolset which is no longer maintained. Arcade SDK is.

Not currently, I was about to switch to that if possible. Whether the official builds build from devdiv or dnceng is orthogonal to Arcade though. Roslyn also builds from devdiv...

DiagnosticWindow is built from Roslyn.sln. @Youssef1313 did you try to rebuild and reinstall the VSIX?

It's not clear to me what code are we trying to reuse between Roslyn and Razor LSP server implementations. Can you list what you envision sharing?

@davidwengier FYI

@axel-habermaier Turns out that the interpreted way is actually faster than the compiled way if the expression is executed less than ~50 times.

I don't think ```MSBuild testapp.csproj /t:VSTest``` should force build on the project. If I wanted to build the project I would have used ```/t:Build;VSTest```.
