Visual Studio & .Net

I am a long time Windows user by requirement. Recently I built a Ubuntu box and am trying to learn that environment. I seem to have over come all obstacles except one.

Writing web pages and code through Visual studio, utilizing .Net 1.x and Visual basic is extremely easy to me and I have been doing so for years. I have a working knowledge of Java script and C# but unfortunately I am best in VB. How do I get Visual Studio to work on Ubuntu or is there a complete environment replacement that will perform all it’s functions.

Thanks for any help,
Stan Ralph
