Q: Has Microsoft built and shipped any products with .NET?

A: A quick look around turns up the following frameworks, applications, and utilities with at least some managed code inside. I'm sure there are others I don't know about.

BizTalk Server, Team Foundation Server, SQL Server Reporting Services, SQL Server Integration Services , Microsoft Small Business Accouting, SharePoint Services, Content Management Server, MSDN Online, Media Center, Visual Studio 2005

What else?
