/// <summary>
/// Creates an event receiver responsible for reading <see cref="EventData" /> from a specific Event Hub partition,
/// and as a member of a specific consumer group.
///
/// A receiver may be exclusive, which asserts ownership over the partition for the consumer
/// group to ensure that only one receiver from that group is reading the from the partition.
/// These exclusive receivers are sometimes referred to as "Epoch Receivers."
///
/// A receiver may also be non-exclusive, allowing multiple receivers from the same consumer
/// group to be actively reading events from the partition. These non-exclusive receivers are
/// sometimes referred to as "Non-epoch Receivers."
///
/// Designating a receiver as exclusive may be specified in the <paramref name="receiverOptions" />.
/// By default, receivers are created as non-exclusive.
/// </summary>
///
/// <param name="partitionId">The identifier of the Event Hub partition from which events will be received.</param>
/// <param name="receiverOptions">The set of options to apply when creating the receiver.</param>
///
/// <returns>An event receiver configured in the requested manner.</returns>
///
/// <remarks>
/// If the starting event position is not specified in the <paramref name="receiverOptions"/>, the receiver will
/// default to ignoring events in the partition that were queued prior to the receiver being created and read only
/// events which appear after that point.
