Hi,
Can you confirm that your nuget feed is available?
https://packages.infragistics.com/nuget/licensed
When trying to access this using the package manager console I am recieving the following error:
[Infragistics] The V2 feed at 'packages.infragistics.com/.../Search() returned an unexpected status code '503 Service Unavailable: Back-end server is at capacity'.
Thanks,
Euan
