```
val createOwned: cancellationToken: CancellationToken -> options: ServerConnectionOptions -> Task<OwnedServerScope>
```

Starts a server on the socket the options name and owns it; disposing the scope stops it.

The core's <c>Server.CreateOwnedAsync</c>, named so F# need not qualify
the type this module shares a name with. A server already listening on
the default socket is refused rather than owned.

## Parameters

- `cancellationToken` (`CancellationToken`)
- `options` (`ServerConnectionOptions`)

## Raises

- [`System.InvalidOperationException`](https://learn.microsoft.com/dotnet/api/system.invalidoperationexception): A server is already listening on the default socket.
- [`LibTmux.TmuxCommandException`](/en/csharp/latest/reference/libtmux-tmuxcommandexception/): tmux failed to say whether a server is listening, such as on a socket it may not open.
