What IDE should I use?

[RandomlyKnighted]

There are a ton of IDE's available for programming in C#. Which one you use is based upon personal preference. I recommend trying out as many as possible to see which one you like the best. Below is a list of available IDE's. This list does not include all of them it just includes the most common ones.

Visual C# Express Edition (2010 and 2008) - www.microsoft.com/express/
Mono (Cross-Platform) - mono-project.com/Main_Page
SharpDeveloper - www.icsharpcode.net/OpenSource/SD/Default.aspx
