Hello,​

Welcome to our Microsoft Q&A platform!

Agree with jcmanke, your MapPage.xaml lack of >

And I notice your demo, lack of CustomMap.cs, I cannot found PTSSRU.Custom;, If you have it in your project?

I am not sure xmlns:local="clr-namespace:PTSSRU;assembly=PTSSRU" it Correct.

If you put CustomMap.cs to Custom folder like following structure, xmlns:local="clr-namespace:PTSSRU.Custom" is correct.
