Deploying an Internet Information Services-Hosted WCF Service
Visual Studio 2010 provides two different ways to deploy a WCF service to be hosted under IIS. Within a WCF Service Application Project you can tell Visual Studio to host the service on the local IIS instance. Or from any WCF project type you can instruct Visual Studio to deploy the service to any IIS instance. You can also manually deploy a WCF service to IIS. For a detailed walkthrough of creating an IIS-hosted WCF service, see How to: Host a WCF Service in IIS.
Before hosting or deploying a WCF service to IIS, make sure that IIS, ASP.NET, and WCF are installed and configured correctly.
Ensure That IIS, ASP.NET and WCF Are Correctly Installed and Registered
WCF, IIS, and ASP.NET must be installed for IIS-hosted WCF services to function correctly. The procedures for installing WCF (as part of the .NET Framework 3.0), ASP.NET and IIS vary depending on the operating system version being used. For more information about installing WCF and the .NET Framework 3.0, see Microsoft .NET Framework 4.0 Web Installer. Instructions for installing IIS can be found at Installing IIS.
The installation process for the .NET Framework 3.0 automatically registers WCF with IIS if IIS is already present on the machine. If IIS is installed after the .NET Framework 3.0, an additional step is required to register WCF with IIS and ASP.NET. You can do this as follows, depending on your operating system:
- Windows XP SP2 and Windows Server 2003: Use the ServiceModel Registration Tool (ServiceModelReg.exe) tool to register WCF with IIS: To use this tool, type ServiceModelReg.exe /i /x in the Visual Studio command prompt. You can open this command prompt by clicking the start button, selecting All Programs, Microsoft Visual Studio 2010, Visual Studio Tools, and Visual Studio Command Prompt (2010).
- Windows Vista: Install the Windows Communication Foundation Activation Components subcomponent of the .NET Framework 3.0. To do this, in Control Panel, click Add or Remove Programs and then Add/Remove Windows Components. This activates the Windows Component Wizard.
Finally you must verify that ASP.NET is configured to use the .NET Framework version 4.0. You do this by running the ASPNET_Regiis tool with the –i option. For more information, see ASP.NET IIS Registration Tool
