I have a quick look on Turbo C# and SharpDevelop. Turbo C# has stronger functions on web application development. I test SharpDevelop 2.0. SharpDevelop has only limited functions on web application development. It seems to aim at a code editor for ASP.Net. But Turbo C# has a complete Rapid development interface for ASP.Net. Moreover, they have some debug function. You need to click "play", then the application will be launched. That 's simple and easy.

Well, SharpDevelop is a open source tool. I am still very happy about its functions. Moreover, it supports .Net 2.0.
