Public Function BeforeInvoke (instanceContext As InstanceContext, channel As IClientChannel, message As Message) As Object

Parameters

instanceContext: InstanceContext

The service instance for the operation.

channel: IClientChannel

The client channel.

message: Message

The incoming message.

Returns

Object

A correlation object passed back as the parameter of the AfterInvoke(Object) method.

Remarks

Implement the BeforeInvoke method to initialize and clean up thread-local storage for the thread that invokes user code. Typical usage is to set some value, such as impersonation or changing the System.Globalization.CultureInfo. If you wanted to establish some custom context, this is the extension point to initialize the static context property, which is then available for developers in the course of the operation.
