Seesmic demonstrated a new desktop client for Twitter, Facebook and LinkedIn today. Since it’s based on Microsoft’s cross-platform Silverlight software, it works on both Windows and Mac computers. Seesmic has also opened the software up to third-party plug-in development.

Seesmic is currenly best known for Microsoft .NET-based Seesmic for Windows, which many Twitter users consider one of the best Twitter clients for that operating system. It also offers a multi-platform client based on Adobe Air called Seesmic Desktop.

The company’s partnership with Microsoft has been carried on with Seesmic Desktop’s integration with Silverlight. Thanks to Silverlight’s development tools, the new desktop platform can bring in plug-ins made by just about anyone. For example, the software can inject Bing Maps into a Tweet when it knows the tweet’s location — which it often will thanks to a recent update to Twitter’s web interface. We’ve included a picture of the Bing Maps integration above.

Seesmic hasn’t said exactly when this stuff will be available, but it sounds like it will be soon. Here are a couple of other screenshots of the new Silverlight-integrated Seesmic Desktop Platform.

A Software Development Kit (SDK) going live at http://platform.seesmic.com/ very soon.
