I have developed Silverlight application using ArcGIS API for Silverlight v1.2 and VS2008. Now I upgraded this application to ArcGIS API for Silverlight v2.4 and VS2010. After this upgrade I am getting below error while loading map layers and associated params like TOC and coordinate system.
An exception of type 'System.ArgumentException' occurred in ESRI.ArcGIS.Client but was not handled in user code
Additional information: 'Url' is not set.
If i click continue in this error message, i am getting another error message in browser. Please refer the attached screen shot.
Please help me to solve this issue.
Thanks,
M.Kumaran.
