Importing and developing WinForms applications on linux

I have a Visual Studio C# project, with a GUI done in WinForms. I'd like to continue its development on Linux. I have two questions: firstly, how can I compile it on Linux? I can compile single .cs files that use WinForms, but I have no idea about whole projects. Secondly, how can I further edit the GUI, other than by code? is there some editor?
