The enumerable sequence of queryable observable sequences.
Type: System.Int32
The maximum number of queryable observable sequences being subscribed to concurrently.
Type: System.Reactive.Concurrency.IScheduler
The scheduler to run the enumeration of the sequence of sources on.

Return Value

Type: System.Reactive.Linq.IQbservable<TSource>
The queryable observable sequence that merges the elements of the queryable observable sequences.
