add symbol and System.Runtime.Serialization error

MariaMaldini

hello , I am working on one of Esri silverlight samples that assign symbol for point features. when i add following codes to assign symbol to point layer :

            <esri:PictureMarkerSymbol x:Key="DefaultClickSymbol" OffsetX="11" OffsetY="39" Source="/Assets/images/i_pushpin.png" />

            <esri:SimpleFillSymbol x:Key="DefaultBufferSymbol" Fill="#660000FF" BorderBrush="Blue" BorderThickness="2"  />

i encounter with this error:
