I’m posting this more as a reminder for myself. Where exactly are you supposed to place XSD files to give you intellisense for XML files in Visual Studio.NET?

Visual Studio.NET 2003

C:\Program Files\Microsoft Visual Studio .NET 2003\Common7\Packages\schemas\xml

Visual Studio.NET 2005

C:\Program Files\Microsoft Visual Studio 8\Common7\Packages\schemas\xml

This is useful for such things as Nant.xsd and UrlRewriting.xsd.

To get intellisense for NAnt, you have a couple of other steps to do.
