Hello Raul,

If you are referring to the 2017.0 installation of the Infragistics Xamarin product, a package source named "Infragistics (Local)" should have been created automatically, which you can use after entering your Infragistics website credentials to install the Xamarin assemblies via NuGet.

If this doesn't appear to exist for you, the NuGet packages should exist in an "Infragistics_Xamarin_NuGet" folder at the following directory:

C:\Program Files (x86)\Infragistics\2017.0\Xamarin\NuGet

If you extract these packages and point a new NuGet package source to the extracted folder, you should be able to add the assemblies via NuGet that way as well.

Please let me know if you  have any other questions or concerns on this matter.

Sincerely,
Andrew
Associate Developer
