Can't add "ESRI.ArcGIS.DataSourcesGDB" reference to Siverlight app.

Question

Hi all,

I can't add those four references to my silverlight application.

I attach the pictures of this process. First I right click the "reference", choose "add arcgis reference", then pick up the references that I want to add. But I click finish button, it seems these four reference can't be added into the reference. I saw them just flashing in the reference tablet, but them disappear fast. I don't know why this happen.

Hope someone can help me !  Thank you!

You cannot add arcobjects .NET libraries in SL project. If you want to use arcobjects you need to create a WCf service in your web project (Applicationname.Web) and add that service reference to your SL project. If you need help in creating a WCF service please follow the following blog
