Hey I followed same steps as you mentioned but when it executes below statement context.ExecuteQueryAsync(new ClientRequestSucceededEventHandler(OnRequestSucceeded), new ClientRequestFailedEventHandler(failed)); it throws this exception."ServerVersion = 'context.ServerVersion' threw an exception of type 'Microsoft.SharePoint.Client.PropertyOrFieldNotInitializedException'" And it doesn't go in any success and failed event handlers. What could be the issue? My code exactly look like:http://msdn.microsoft.com/en-us/library/ff728647.aspx Thanks in advance. Waiting for your response.
