Or does it also run in other browsers? The information I'm reading is confusing.
Thanks
You can check out the MSDN docs here: http://msdn.microsoft.com/en-us/library/cc716877.aspx
There is a previous thread about this as well: XBAP Application, can these work in Google Chrome?
It can also run in Firefox [And might likely work for other NetScape-Plugin-Aware browsers].
