I'm using VS2010 , Esri Silverlight API 2.4, but shows in properties as run time version 2.0, I'm a little confused as to which one it really is using that may be causing the issue. The path folder reflects v2.4 in my Esri.ArcGIS.Client reference properties. I have approximately 21 errors all showing the warning below in my mainpage.xaml.
Warning 1 'ESRI.ArcGIS.Client.ScaleBarUnit' is obsolete: '"Please use ScaleLineUnit in the ESRI.ArcGIS.Client.Toolkit namespace."'
I'm not sure what to change, I'm VERY new to Silverlight API's. I'm actually just trying to get started and trying to open up and utilize the Frosted Tabs Template I downloaded so there is nothing special added yet, it is just the code in the template that isn't working.
