Yeah ok looks like it’s a serious issue that needs to address in the CoreFx libraries, we’ll have to wait to see how MS addresses it before hard coding a solution in the code-base. In the meantime I’ve added a flag you can disable to prevent accessing the problematic NetworkInformation APIs:
IPAddressExtensions.AccessNetworkInterface = false;
There seems to be some movements on the issue, so I’ll wait till they reach a conclusion before pushing out another .NET Core release.
