Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetServiceInstance()

Returns the instance of the service for the instance context.

System_CAPS_pubmethodGetServiceInstance(Message)

Returns the instance of the service for the instance context in response to an incoming message.

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethodIncrementManualFlowControlLimit(Int32)

Increases the number of messages that can be processed by the service instance.

System_CAPS_pubmethodOpen()

Causes a communication object to transition from the created state into the opened state.(Inherited from CommunicationObject.)

System_CAPS_pubmethodOpen(TimeSpan)

Causes a communication object to transition from the created state into the opened state within a specified interval of time.(Inherited from CommunicationObject.)

System_CAPS_pubmethodReleaseServiceInstance()

Releases the service instance.

System_CAPS_protmethodThrowIfDisposed()

Throws an exception if the communication object is disposed.(Inherited from CommunicationObject.)

System_CAPS_protmethodThrowIfDisposedOrImmutable()

Throws an exception if the communication object the State property is not set to the Created state.(Inherited from CommunicationObject.)

Occurs when a communication object transitions into the opened state.(Inherited from CommunicationObject.)

System_CAPS_pubeventOpening

Occurs when a communication object transitions into the opening state.(Inherited from CommunicationObject.)

The following code illustrates how to obtain instance context information from a service:

string info = "";

OperationContext operationContext = OperationContext.Current;
InstanceContext instanceContext = operationContext.InstanceContext;

info += "    " + "State: " + instanceContext.State.ToString() + "\n";
info += "    " + "ManualFlowControlLimit: " + instanceContext.ManualFlowControlLimit.ToString() + "\n";
info += "    " + "HashCode: " + instanceContext.GetHashCode().ToString() + "\n";

return info;
