Error in ArcGIS API 3.0 silverlight templates MainPage.xaml file in Visual studio

PhanindraKuchipudi — Tue, 14 Aug 2012 10:40:56 GMT

I am trying to develop a silvelight map application using 3.0 API and silverlight 5. I have downloaded example templates from template gallery and when I try to open them in visual studio 2010(professional edition) MainPage.xaml designer is showing method not found error. When I try to reload the designer, it is opening for fraction of seconds and going to error again. I couldn't find out the problem behind it. If there is an error, designer should not load after clicking reload also....but why it is opening for a fraction of seconds and why it is going to error then. When I debug, application is getting opened in browser without error.

I am really confused how to make changes in MainPage.xaml design. Can anyone help to find out what method is missing to load the designer properly?

Do you have the expression blend sdk installed? http://www.microsoft.com/DOWNLOADS/DETAILS.ASPX?DISPLAYLANG=EN&FAMILYID=D197F51A-DE07-4EDF-9CBA-1F1B4A22110D

I have the Blend SDK installed, SL 5 Tools, etc. I've compiled, cleaned, recompiled. I still get this error when loading MainPage.xaml. The installed templates (Showcase and Standard) load just dandy.

Any other suggestions?

Figured out the issue. The Image resources weren't being recognized as resources in the solution. I tried excluding/including them and removing/adding them with no luck. I finally just put the URI right in the image tag on MainPage.xaml.

Sorry for the hijack, and all the self-replies.

I'm getting a ton of Unhandled Exception Errors with the 3.0 api and Silverlight 5.0. If I remove references in my older application (2.4/4.0) it still works, or I get actual errors. Using this template with the newer stuff, everything is unhandled. What am I doing wrong here?
