Development tools

Several available software packages exist for developing ASP.NET applications:
Microsoft Expression Web, part of the Microsoft Expression Studio application suite.
Visual Studio .NET (for ASP.NET 1.x)
ASP.NET Web Matrix (for ASP.NET 1.x; now no longer supported: replaced by the free Visual Web Developer 2005 Express Edition)
Visual Web Developer 2005 Express Edition or Visual Studio 2005 (for ASP.NET 2.0)
Visual Studio 2008 or Visual Web Developer 2008 Express Edition (for ASP.NET 3.5)
Macromedia Dreamweaver MX, Macromedia Dreamweaver MX 2004, or Macromedia Dreamweaver 8 (doesn't support ASP.NET 2.0 features, and produces very inefficient code for ASP.NET 1.x: also, code generation and ASP.NET features support through version 8.0.1 was little if any changed from version MX: version 8.0.2 does add changes to improve security against SQL injection attacks)
Macromedia HomeSite 5.5 (For ASP Tags)
Microsoft SharePoint Designer 12
Delphi 2006
MonoDevelop (Free/Open Source)
SharpDevelop (Free/Open Source)
