Silverlight web service times out after 60 seconds

For Silverlight apps with web services calls that time out after 60 seconds:

You've set httpRuntime executionTimeout and binding SendTimeout, but your app still times out after 60 seconds. The problem is the CLIENT, not the server, is timing out.

In your Silverlight app, set a timeout after you instantiate your service client. For example, set a 30 min timeout on your service called "mySvc:"

mySvc.ChannelFactory.Endpoint.Binding.SendTimeout = New TimeSpan(0, 30, 0)
