Error Deploying Chilkat .NET Core to Windows Mobile ARM

I have a UWP project

VS2017 Enterprise
NETFX_CORE,WINDOWS_UWP

If I deploy to Windows 10 Pro – x86 – Works perfectly

I get an error when the same project is deployed to:
Windows 10 Mobile ARM (Insider Preview – Fast Ring – Ver1709 – OS build 10.0.15252.

The error is:
