Error connecting to service using AdomdClient (.Net)

Hi,

I am trying to connect to the PowerBI service using the AdomdClient. I have installed the Sql2016 feature packs bits for SQL_AS_OLEDB and SQL_AS_ADOMD (Microsoft.AnalysisServices.AdomdClient.dll -> v13.0.0.0)

I can connect fine using COM/ODBO, but obviously using the .Net lib is far nicer. The connection string is out of the odc file I downloaded. I don't change the connection string between COM and .Net.

Hopefully the info below is sufficient, but if not please let me know!

Thanks

Colin
