This may because the NuGet is not installed in the iOS project. Can you confirm this?

[jamesmontemagno]

Additionally, please fill in all basic information for us in the Issue.

I assume you are trying on a Simulator which I don't believe supports the dialer.

I think you might need to add the queries things to manifests and plists now. I'm in bed atm so I'll have links tomorrow. But maybe check out the email/dialer since and there might be some links and sample code.

I know @jamesmontemagno wrote them.
