The answer to your latter question is: no. Only pretty trivial stuff is portable to Mono. I've tried it on every project I've worked on over the last 6 years to no avail. Show stopper every time.
I'm currently in a web app team with a C# backend. Two devs run Windows, one has a Mac, and one runs Ubuntu. It works great. And yes, we deploy to Linux using Docker.
I agree with you but I wouldn't do it myself.
You say that like it's the most trivial thing in the world. Most people attempting Mono have been loyal Windows-based .NET developers for years. Mono only has value for them if they can port their legacy apps from Windows and .NET to Mono.
then it cannot replace .net .You can put it every ways you want serious C# and .net development is windows only.
Mono doesnt run every C# library out there.
The people pushing mono here dont have to face the consequences of that choice.
It's easy for them to say "it just works", they wont be around when one realises it doesnt work. Dont use mono thinking it really works.It's an experiment.
I wish one day microsoft will be forced to port/support .NET (at least server components) to linux but I'm not holding my breath...
Client-side. No WPF and WinForms is dreadfully incomplete.
It's a no go. If you start on Mono and deploy to .Net I imagine it'd work but no-one realistically does that these days. If they were going to do that, Java would be a better choice for the product.
Not that I want to use any of them myself :)
