The C# (and VB) compiler that will be used in the next version of VS (which is what this project is all about) is fully open source and up to date.

The parts of the .Net library that are written in C# are published at http://referencesource.microsoft.com/ and should be up to date, but they're not open source.

AFAIK, there is no up to date version of the native part of CLR published anywhere.

Does that mean, we can't use latest .NET 4.5 framework and C# 5.0, on open-source OS such as Ubuntu ?

Thank you for your information !

If you want to use C# on Ubuntu, use Mono: http://www.mono-project.com/

Even if .NET was fully open-source, you couldn't just compile and run it on any OS, it has dependencies on the Windows API.
