I need a better solution than just increasing my extents... I understand that the "black"/shadow areas are occurring outside my area of extents, but they shouldn't. Those should just be normal tiles without an overlay. If I increase my extents, with the area sizes I am dealing with, then I am going to have a huge cache of useless 1kb tiles. It appears as if the PNGs coming out of GeoWebCache are 32 bit. I thought these might work, and they are great in my extents, but I can't have these "black"/shadow areas if you want to like a tan line on a beach. This should be a Microsoft Silverlight problem that needs to be fixed on their side. Check out this article: http://viswaug.wordpress.com/2009/04/01/lack-of-good-transparency-support-in-silverlight-and-what-it-means-to-online-mapping-maps/ Very Frustrating.

Could make the transparent tile configurable. Feel free to file a feature request ticket on geowebcache.org

Maybe, try this:
You can unpack geowebcache.jar , look for blank.png, replace it with another PNG and repack.

To replace the default 8 bit blank.png with the attached 24bit blank png,
In the directory where geowebcacahe-1.1.0.jar lives, create a subdirectory org/geowebcache
Put the attached png there and name it blank.png
Update the jar:
jar uf geowebcache-1.1.0.jar org/geowebcache/blank.png
Test it by extracting and seeing if it is the new one (it is 662 bytes, the old one is 129 bytes)
jar xf geowebcache-1.1.0.jar org/geowebcache/blank.png
You will need to clear your browser cache to see the difference in the Silverlight map control.
It worked for me...
