Recently, I decided to upgrade my project to Silverlight 5. When I do this, if I continue to use ESRI's Silverlight API 3.1, my project compiles successfully (using Visual Studio 2012) , but an error appears in the "Errors" window with a description of "[Line 0 Position 0]" and all of my ESRI controls (Map, Navogation, etc.) have a blue, squiggly underline in the XAML editor. Is there a known cause for this? I've not been able to find any mention of it here or on Stack Overflow.</P></BODY></HTML> Wed, 07 Jan 2015 16:38:59 GMT https://community.esri.com/t5/arcgis-api-for-silverlight-questions/esri-silverlight-api-3-1-silverlight-5/m-p/191832#M4746 ThomasBoring 2015-01-07T16:38:59Z Re: ESRI Silverlight API 3.1 & Silverlight 5 https://community.esri.com/t5/arcgis-api-for-silverlight-questions/esri-silverlight-api-3-1-silverlight-5/m-p/191833#M4747 <HTML><HEAD></HEAD><BODY><P>If it's a design time only problem (i.e your project executes correctly) it might be a cache issue.
