InstanceContext.GetServiceInstance Method
Microsoft Silverlight will reach end of support after October 2021. Learn more.
Returns the instance of the service for the instance context in response to an incoming message.
Namespace: System.ServiceModel
Assembly: System.ServiceModel.Extensions (in System.ServiceModel.Extensions.dll)
Syntax
'Declaration
Public Function GetServiceInstance ( _
message As Message _
) As Object
public Object GetServiceInstance(
Message message
)
Parameters
- message
Type: System.ServiceModel.Channels.Message
The incoming message that triggered the creation of a service object.
Return Value
Type: System.Object
The object that represents the service instance.
Exceptions
| Exception | Condition |
|---|---|
| InvalidOperationException | The service instance is in a created or opening state or is not initialized. |
| CommunicationObjectAbortedException | The service instance is aborted. |
| ObjectDisposedException | The service instance has been closed already and cannot be modified in these states. |
| CommunicationObjectFaultedException | The service instance is faulted and cannot be modified in these states. |
Remarks
The general idea is that you create an instance of the service only when a message directed at it arrives, by calling Open; then if no message arrives, no InstanceContext is created and no service object is created, and so resources are not deployed until actually required.
