title: Upgrading Blazor project to Net Core 6 breaks Websocket
body: <p>I've had a Blazor project built in Net Core 5, but wanted to test new functionality of Net Core 6 previews. After upgrading the framework, I tried to build the app but got greeted by a single error: &quot;WebSocket is not in the OPEN state&quot;. I've tried to use some solutions I've found to no avail. Not even the full release has helped me.</p>
