Is there any application by Microsoft targeting the end user market and running on the .NET framework?

It's all in the title. Inspired by http://www.reddit.com/r/programming/comments/dx8au/lessons_from_evernotes_flight_from_net/

Edit: I am primarily thinking about deskt开发者_Go百科op apps, not web apps.

I think you'll hardly find mainstream apps from Microsoft written in .NET, since most of their popular applications were built before .NET was released, re-writing them for .NET provides no benefit for them.

But if you look at recent applications you might find .NET based ones:

• Business Contact Manager (mentioned by Martin)
• SQL Management Studio
• Windows Live Essentials
• Power Shell (and Exchange + all other management shells based on PS)
• MMC in Windows (Vista,7,2008)

I know that some are not consumer based, but it shows that recent investments were made on .NET

All of Microsoft's websites run ASP.Net.

Expression Studio, parts of which target end-users, is built in .Net and has a WPF-based UI.

Visual Studio's 2010 GUI is written using WPF. The application is not completely managed though.

Most of Microsoft Dynamics are written (or have significant porttions written) in .NET

Business Contact Manager

Windows Live Writer is one - at least the last two versions (and IIRC, all versions since it was first released) are ground-up WinForms.
