ApplicationQueuingAttribute Class

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
/** @attribute AttributeUsageAttribute(AttributeTargets.Assembly, Inherited=true) */ 
/** @attribute ComVisibleAttribute(false) */ 
public final class ApplicationQueuingAttribute extends Attribute
AttributeUsageAttribute(AttributeTargets.Assembly, Inherited=true) 
ComVisibleAttribute(false) 
public final class ApplicationQueuingAttribute extends Attribute

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