I'm playing with a Silverlight app in Visual Studio so that I can learn programming with the API for Silverlight. I created a feature layer that points to a fire stations map service on our ArcGIS Server. I'm following the example in the getting started pages for creating a symbol in the Grid.Resources tag and using it as a static resource for the FeatureSymbol property of the FeatureLayer. When I comment out the SimpleMarkerSymbol tag in Grid.Resources, it builds fine, but won't run because it can't find the reference to MyMarkerSymbol. When I include the SimpleMarkerSymbol tag in Grid.Resources, I get a build error. Below are the error and my code. Any help would be appreciated.
Thanks, Doug

WRN: Assembly binding logging is turned OFF. To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1. Note: There is some performance penalty associated with assembly bind failure logging. To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].
