To host WCF services in Azure, start by opening VS2010 and starting a new cloud project. Name the new project something like “WCF_Cloud_AzureProject.” Add a new WCF Service Web Role project and name it “WCF_AzureDataService.” Rename IService1.cs to IService.cs and Service1.svc to Service.svc to ensure Azure compatibility. Create a new ADO.NET Entity Data model in the WCF project and give it a name, such as “CompanyInfo.” Finish the Azure project wizard. Add an operation contract if needed. Test the WCF service functionality by pressing the F5 button on your keyboard. Now you can click the “Publish” option and initiate cloud operations for the WCF services.
