Enables queuing support for the marked assembly and enables the application to read method calls from Message Queuing queues. This class cannot be inherited.

Namespace:  System.EnterpriseServices
Assembly:  System.EnterpriseServices (in System.EnterpriseServices.dll)

[AttributeUsageAttribute(AttributeTargets.Assembly, Inherited = true)]
[ComVisibleAttribute(false)]
public sealed class ApplicationQueuingAttribute : Attribute

For a list of initial property values for an instance of ApplicationQueuingAttribute, see the ApplicationQueuingAttribute constructor.
