The best user friendly editor for asp.net applications

There are lots of free editors available online although it depends on whether it is a PC or a MAC Operating System. However, Notepad++, SharpDevelop and Visual C#2010 express are some of them.
I reckon that visual C# 2010 Express edition is the best tool. It is free and available for download from the Microsoft / download.
Another good choice is Sharp Develop because it supports intelligence, toolbox, and many more features that are also available in Microsoft Visual C# Express edition.
Although both programs have great features, Microsoft Visual C # 2010 Express Edition is the most preferred because of its documentation, examples and screenshots that help get users started.
You may want to download Visual C# express edition.
