WmtsLayer loading exception

KarlBarkmann

Hello,there.Sorry about my poor english.

I am adding a  wmtslayer by using the following code.

But there is a exception occurs while WmtsService loading.

The Exception says:Invalid XML.: Parser couldn't move inside Keywords.

Here's the call stack:

在 System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw()
在 System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)
在 System.Runtime.CompilerServices.TaskAwaiter.GetResult()
在 ArcGISRuntime.WPF.Samples.WMTSLayer.WMTSLayer.<Button2_Click>d__2.MoveNext() 位置 C:\Workbench\sources\arcgis-runtime-samples-dotnet-master\src\WPF\ArcGISRuntime.WPF.Viewer\Samples\Layers\WMTSLayer\WMTSLayer.xaml.cs:行号 72

Any idea why this exception happens?

You can find the capacities xml from attachment.
