I am not sure if something has been changed in new version of DOT NET SDK but I faced the same issue with DOT NET SDK version 5-7-6. It got connected to ThingWorx 8.4 but the same code did not connect to Thingworx 9.0. But I just connected DOT NET SDK version 5-8-0 to ThingWorx 9.0. Please test with SDK version 5-8-0 or above.

Thanks,

That's great. But just FYI DOT NET SDK latest version is not certified with ThingWorx 9.0 - http://support.ptc.com/help/thingworx/edge_sdk_dotnet/en/index.html#page/dotnet_sdk/c_edge_sdk_dotnet_helpcenter_welcome.html
