Microsoft doesn’t intend to launch Windows Phone 7 without a large selection of useful software to run on the new devices.  Today at MIX10, the company announced a list of software and Web companies who are currently onboard and busily working on Windows Phone 7 apps.

The list is fairly long and available at Engadget Mobile, but some of the companies that caught our eye include EA Mobile, Photobucket, Pandora, Shazam, Sling Media, Fandango, Citrix, the AP, and IMDB.

Between now and Windows Phone 7’s launch near the end of the year, this list of software partners will continue to grow.  And before long we should begin seeing some of this software demoed.
