Can't register hub. Use RegisterHub

[wd45T]

I'm using the example from the documentation, but an error occurs when registering the hub.

System.InvalidOperationException: 'No service for type 'Microsoft.AspNetCore.SignalR.HubLifetimeManager`1[HubsLib.TestHub]' has been registered.'

siloBuilder
    .UseSignalR()
    .RegisterHub<TestHub>();
    
public class TestHub : Hub
{
}
