ASP.NET is Platform independent or not?
in which OS supported to .NET

More or less.

Originally, ASP.NET, part of .NET runs only on Windows as it's all developed by Microsoft.

However, there's an open source implementation that tries to mimic .NET as much as possible. It's called Project Mono and can be found here: http://www.mono-project.com/Main_Page
