I am attempting to build a Silverlight/XAML application to run on WEC 7 following the instructions at http://developer.toradex.com/knowledge-base/how-to-create-a-silverlight-application.
I successfully installed all of the pieces, including VS2008 and its updates, Expression Blend 3, Windows Embedded Silverlight Tools and the CE7 SDK.
When I got to the step to create a new VS2008 project with the template Silverlight for Windows Embedded Application, filled in the Name and pressed OK, an error dialog popped up with the message:
Windows Embedded Silverlight Tools,
DataSource file could not be found
After several fruitless hours of troubleshooting, I randomly uninstalled the CE8 SDK. This seems to have fixed the problem and I can now create a Silverlight/XAML project with VS2008 for WEC7.
[I had installed CE8 SDK on previous day while playing with WEC 2013].
It would be nice to have both CE7 and CE8 SDKs installed at the same time as I am evaluating both WEC 7 and WEC 2013.
