public static IQbservable<TSource> AutoConnect<TSource>(this IQbservableProvider provider, IConnectableObservable<TSource> source, int minObservers, Expression<Action<IDisposable>> onConnect)

Summary: Automatically connect the upstream IConnectableObservable at most once when the specified number of IObservers have subscribed to this IObservable.

Type parameters

Name	Description
`TSource`	The type of the elements in the source sequence.

Parameters

Name	Type	Description
`provider`	[IQbservableProvider](#	Query provider used to construct the [IQbservable](# data source.
`source`	[IConnectableObservable](#	Connectable observable sequence.
`minObservers`	int	The number of observers required to subscribe before the connection to source happens, non-positive value will trigger an immediate subscription.
`onConnect`	Expression>	If not null, the connection's IDisposable is provided to it.

Returns: IQbservable -- An observable sequence that connects to the source at most once when the given number of observers have subscribed to it.

Exceptions

Type	Condition
System.ArgumentNullException	`source` is null.
