Thanks for sharing, there's been a few skills tied to dotnet11 we've been looking at here and here. None of them cover the process API updates though. Would be nice to have those as well - we'd love contributions.

@adamsitnik - who authored the new Process APIs

Hello @Meir017

It's great idea and it's definitely on my TODO list for .NET 11.

After first early adopters started using the new APIs I've received some feedback and I want to provide even few more "one-liners" like dotnet/runtime#128453. When I get all of them merged, I am going to publish the new skill. So it won't be just "how to use the new APIs to get the job done" but also "how to solve common anti-patterns with the new APIs".

Thanks,
Adam
