The installer class, which inherits from Installer , allows the program to be installed as an NT service by the Installutil. The following sample shows the configuration of the base address as well as the endpoint that exposes the CalculatorService.
When you run the sample, the operation requests and responses are displayed in both the service and client console windows. To build the C or Visual Basic. After the solution has been built, run Setup.
The service should appear in Services. To run the sample in a single- or cross-computer configuration, follow the instructions in Running the Windows Communication Foundation Samples. Skip to main content.
This browser is no longer supported. To create this project, you can simply take a " Windows Service" , while choosing from project wizard option. In this module at the start of the service, an infrastructure will be created to expose the service, and when the service is stopped, all objects are disposed. Add a member variable ServiceHost type. As the name implies, ServiceHost provides a host for services. The OnStart handler is called, when the said service is started through service control panel, or command line or otherwise , it does the following things.
CalcService and its base addresses adrbase specified. ServiceMetadataBehavior class controls the publication of service metadata and associated information, although. Adding just behavior to the service is not sufficient for publication of metadata, you must add an IMetadataExchange endpoint to your service for each supported binding type. Windows service needs to be installed, and should be running, you can install the service using InstallUtil.
This utility is part of the SDK, the path is set, when you run this utility through Visual Studio command prompt. This utility is the part of the SDK, the path is set, when you run this utility through Visual Studio. Once the service has been built, and deployed, it is time to create the client. This hosting option consists of registering the application domain AppDomain that hosts a WCF service as a managed Windows service so that the process lifetime of the service is controlled by the Service Control Manager SCM for Windows services.
The service code includes a service implementation of the service contract, a Windows Service class, and an installer class. The CalculatorWindowsService is a Windows service. In OnStop , the service is stopped and disposed. The host is also responsible for providing a base address to the service host, which has been configured in application settings. The installer class, which inherits from Installer , allows the program to be installed as a Windows service by the Installutil. Implement the service contract in a class called CalculatorService as shown in the following code.
Add a local variable called serviceHost to reference the ServiceHost instance. Define the Main method that calls ServiceBase. Run new CalculatorWindowsService. Override the OnStart String[] method by creating and opening a new ServiceHost instance as shown in the following code.
Override the OnStop method closing the ServiceHost as shown in the following code. Create a new class called ProjectInstaller that inherits from Installer and that is marked with the RunInstallerAttribute set to true.
