topic Project Templates Stopped Working in ArcGIS API for Silverlight Questions https://community.esri.com/t5/arcgis-api-for-silverlight-questions/project-templates-stopped-working/m-p/592141#M15171 <HTML><HEAD></HEAD><BODY><SPAN>I have a silverlight solution that is based on the ESRI Standard Template. Yesterday, it started to fail when compiling and gave me the error - "XAML Namespace </SPAN><A href="http://schemas.microsoft.com/expression/blend/2008">http://schemas.microsoft.com/expression/blend/2008</A><SPAN> is not resolved". Which doesn't appear to have to do with anything that i've modified in the template.</SPAN><BR /><BR /><SPAN>Upon further inspection, creating a project from scratch using the ESRI Templates no longer behaves as expected. In Expression blend it simply won't compile &amp; in VS2010 nothing renders in the design view (although the app will launch from vs2010). I have tried uninstall/reinstall of the ESRI Silverlight/WPF SDK as well as all the dependencies (VS2010 w/ silverlight 4 tools, Blend4) only to experience the same results.</SPAN><BR /><BR /><SPAN>At this point, I'm kind of stuck without access to any sort of designer. Any ideas?</SPAN></BODY></HTML> Tue, 25 May 2010 11:23:38 GMT DonnieHolmes 2010-05-25T11:23:38Z Project Templates Stopped Working https://community.esri.com/t5/arcgis-api-for-silverlight-questions/project-templates-stopped-working/m-p/592141#M15171 <HTML><HEAD></HEAD><BODY><SPAN>I have a silverlight solution that is based on the ESRI Standard Template.
