Q:

Windows phone Microsoft.Phone.Media.Extended.dll file

How do I get Microsoft.Phone.Media.Extended dll file for my project? I am unable to find this anywhere. Can someone help me?
Thanks
Jai

A:

You have to be aware that this DLL is not a part of the public SDK, therefore your application will not pass Marketplace certification if it is using it. You can get it by dumping the emulator OS image, for example, to get the GAC.
Or you could use reflection. I worked on that here.
EDIT: Since you need to access the flash, are you aware of this? It's been in Mango for a while now:
