Also, you have the option of using the TW.AnalysisServices.AnalyticsServer.AnalyticsServerConnector native to Analytics Manager, instead of using the Standalone MicroServices.
I don't have the "TW.AnalysisServices.AnalyticsServer.AnalyticsServerConnector" as an available provider. I have installed the 8.3.0 as well as the 8.3.1 Analytics Extensions and it is still not available.
