Host WCF Service in Azure App Service


In this article we will discuss on the procedures to host a WCF Service on WebApps in Azure  App Service. Azure App Serivce consists of four sub types and they are

  • Web Apps    – Provides hosting service for Web Applications
  • Mobile Apps – Provides a mobile-application development platform that’s highly scalable.
  • Logic Apps   – Provides a visual designer to automate the business process in a series of workflow
  • API Apps      – Provides design and hosting services for Rest API


Usually we use Cloud Services on Azure to host WCF services. While Cloud Services hosting works as expected, the requirement we got was to find an option to host wcf service using one of the features in Azure AppService itself.

We can use WebApps feature to host the WCF in Azure AppService. Follow along this article to find out the procedures.

How to access WCF Service in Asp.Net Core Application


How to access WCF Service in Asp.Net Core Application


In this article I will explain how to consume WCF Service in Asp.Net Core Web Application. In previous .Net Framework we have multiple options to consume a WCF service.  We have the options like Add Service Reference, SvcUtil,  ChannelFactory etc. However in Asp.Net Core there is a slight difference in Consuming WCF Service. In Asp.Net core you will notice that, we don’t have the option “Add Service Reference like in the older .Net Framework.  The solution for this is WCFConectedService.

WCFConnectedService: Core team has come up with an extension called WCFConnectedService, This is a Visual Studio extension for generating SOAP service references in the Asp.Net Core application. This extension can be used with any project types in core.

We use ConnectedService to access a WCF Service in Asp.Net Core Web Application.

Installing WCF Connected Service Extension:

Below are the steps to install WCF Connected Service Extension in Asp.Net Core WebApplication

  • Right Click on the Connected Services Option


If the Extension is not installed then you will see the below window. User need to click on Find more Services link
