Completely wiped out the debug directory manually via Windows Explorer, some of the files weren't getting updated</SPAN><BR /><SPAN>2. This was probably the real issue, there was a mismatch of ArcGIS Silverlight SDK/Extensibility SDK assemblies between the development box I was using and my local ArcGIS Server, I noticed this mismatch when reviewing the solution's references Path attribute, I upgrade the dev box and started from scratch with the example and all was well.</SPAN><BR /><BR /><SPAN>Regards</SPAN></BODY></HTML> Wed, 29 Feb 2012 12:00:22 GMT https://community.esri.com/t5/arcgis-viewer-for-silverlight-questions/extensibility-sdk-visual-studio-template-not/m-p/200644#M608 RonaldLopez 2012-02-29T12:00:22Z
