ShutdownDefaultChannelsAsync()
public static Task ShutdownDefaultChannelsAsync()
Shuts down any channels automatically created by Create() and CreateAsync(CancellationToken). Channels which weren't automatically created are not affected.
Returns | |
---|---|
Type | Description |
Task | A task representing the asynchronous shutdown operation. |
After calling this method, further calls to Create() and CreateAsync(CancellationToken) will create new channels, which could in turn be shut down by another call to this method.
