in reply to Leveraging Perl to learn C#
I've been playing around using C# two years ago. Maybe these links are useful to you:
http://icsharpcode.net/OpenSource/SD/Default.aspx - free IDE for C#
http://asp.net/Default.aspx?tabindex=0&tabid=1 - free IDE especially for ASP.NET WebApps from Microsoft
I suggest you to install Microsofts SDK for .NET - it's also freely available and includes a lot of documentation and tutorials.
