Re: Any MS devs looked at this?
Good question @sabroni - lots of haters here. It's clear from the negative posts that many have never tried using the latest MS tools to build for for Linux, and none have persevered. So they are just ill-informed opinion. I see the poeple who have tried it are positive.
I build and support .NET Core APIs and Apps which all run on Linux, both natively and in containers, and it works brilliantly - easy dev environment which lets you focus on the work and deliver working code. Microsoft's dev tools work well. Yes, Visual Studio doesn't run on Linux, but the deployment is easy. The "friction" is no greater than getting setup with Java (which I also use) - probably less if you take fiddling around with Maven files etc into account.
Have fun and don't be put off!
