Aspnet SignalR server connection not disposed when app shuts down

[bjqian]

Describe the bug

When the web app shuts down, due to the adhoc configured here :
All the componets that are injected into the default resolver will be disposed.
But the server connections are managed by serviceManager which doesn't dispose them :

azure-signalr/src/Microsoft.Azure.SignalR.AspNet/ServerConnections/ServiceConnectionManager.cs

Line 136 in 53f7d05

{

To Reproduce

In the example:

azure-signalr/samples/AspNet.ChatSample/AspNet.ChatSample.SelfHostServer/Program.cs

Line 9 in 53f7d05

class Program

add a delay after the using of WebApp.Start. Press enter in cmd line to trigger dispose. Then the app server will get intp a stucking mode:
The server connection is still alive but it will throw exception like "Cannot access a disposed object.Object name: 'LoggerFactory'.""}. when client connect event is triggered.
