I am trying to develop using Alpaca Market Data websocket. When I try to authorize using my paper keys, I got a response WaitingForActivation. The keys are used actively in an app already, and works.
This is my first time using websocket, so I might have missed something.

you could use this as a template of using the streaming api:

I am using VB.NET at the moment. You have a C# library, I might start using it.
Do you have any feedback on the websocket implemented there?

it should work the same way as the python websocket
