This article mainly introduces "what is the WCF monotone service". In the daily operation, I believe many people have doubts about what the WCF monotone service is. The editor consulted all kinds of materials and sorted out the simple and easy-to-use operation methods. I hope it will be helpful to answer the questions of "what is the WCF monotone service?" Next, please follow the editor to study!

WCF supports three types of instance activation:

◆ monotone service (Per-Call Service): each client request allocates a new service instance. SingleCall mode similar to Net Remoting

◆ session Service (Sessionful Service): one service instance is assigned to each client connection. Client activation mode similar to Net Remoting

◆ singleton service (Singleton Service): all clients share the same service instance for all connections and active objects. Similar to Net Remoting's SingleTon mode.

The service activation mode here is configured by the context mode InstanceContextMode attribute of the service we defined, and the code is as follows:

Public enum InstanceContextMode {PerSession, PerCall, Single}

WCF monotonous service Call Service)

WCF monotone service (Per-Call Service): each client request allocates a new service instance. The life cycle of a service instance is tightly limited to the beginning and end of a call. Each request from the client generates a new service instance in response to the call. Similar to Net Remoting's SingleCall mode. The steps are as follows:

The ◆ client invokes the proxy, which forwards the call to the service.

◆ WCF creates a service instance and then invokes the method of the service instance.

◆ when the method call returns, WCF calls the IDisposable.Dispose () method if the object implements the IDisposable interface.

The ◆ client invokes the proxy, which forwards the call to the service.

◆ WCF creates an object and then invokes the object's method.
