Could not load file or assembly 'System.Runtime.Serialization, Version=2.0.5.0

[AngelGonzalez]

I am just doing a simple SL app to just display a map. When I add the esri:PictureMarkerSymbol I get the following error when I build the solution:

"Could not load file or assembly 'System.Runtime.Serialization, Version=2.0.5.0, , Culture=neutral, PublicKeyToken=7cec85d7bea7798e' or one of its dependencies. The system cannot find the file specified."

If I comment out the esri:PictureMarkerSymbol xaml I can build the solution without error.

Any clues?

I am using VS10, ESRI 2.0 API beta and the 3.5 .Net Framework.

Thanks

Add a reference to 'System.Runtime.Serialization'

[JackCibor]

Add that reference to the code behind?? Or in the XAML?

Neither worked for me so I am doing something wrong. But figured that bit of info could help with debugging.

Neither, the reference is to be made in the Reference folder of your Visual Studio project. Right click on the folder and click on "Add Reference..."

Adding the refrence for 'System.Runtime.Serialization' solved the problem.
