I fielded a question this week that may help other Silverlight 4 developers working with Esri products. The question was how to add records to a table that lives inside a geodatabase. While there is probably more then one way to skin this cat, here is one way to do this if you've got the Silverlight Toolkit installed.
In short, I used the Feature Service. If other people have a different implementation feel free to share.
