XBAP with FireFox and Windows 7

Firefox depends on an extension and plugin installed by the .NET 3.5 installer to run XBAPs. Unfortunately, in Windows 7 the .NET 3.5 runtime is already installed.

Does anyone know how to get a hold of these plugins/extensions so you can actually deploy XBAPs to FireFox on Windows 7?

+1  A: 

Turn out, the answer is to copy the DLL of the extension out of another (presumably XP) machine that can run the .NET 3.5 runtime and deploy it.

I'm uncertain of the legality of this maneuver, but it works.

What is the name of this DLL?

Found it: NPWPF.dll. I took the DLL from a WinXP installation with .NET 3.5 SP1 under C:\WINDOWS\Microsoft.NET\Framework\v3.5\Windows Presentation Foundation\NPWPF.dll, placed it into C:\Program Files\Mozilla Firefox\plugins, restarted firefox and it worked.

Thanks for that, You'd think MS would release an installer or register the plugin with mozilla... dont know how im going to roll this fix out to clients :(

I can also confirm that it works (this workaround)
