IContextManager Interface


Defines an interface that allows you to get and set the context on the channel.

Namespace:   System.ServiceModel.Channels
Assembly:  System.ServiceModel (in System.ServiceModel.dll)

public interface IContextManager


Gets or sets a value that indicates whether the context management is enabled.


Gets the context.

System_CAPS_pubmethodSetContext(IDictionary<String, String>)

Sets the context.

For channels that use WSHttpContextBinding with the NotAllowed value set, the context cannot be retrieved on the client using IContextManager because a new channel that establishes a session is created each time GetProperty<T> is called to enforce NotAllowed semantics on a channel. This means that even though the context is properly propagated back to the client in this case, it cannot be retrieved using IContextManager. You can still retrieve it using ContextMessageProperty as shown in the following code.

using (new OperationContextScope((IContextChannel)channel))
    ContextMessageProperty context;
    if (ContextMessageProperty.TryGet(OperationContext.Current.IncomingMessageProperties, out context))
