In this tip, I will explain how you can get rid of the ‘Anonymous Authentication’ exception of WCF service hosting on IIS, that you create in 3.5 framework.

Introduction

Let’s take a real current scenario. I have a web service in a website (.NET framework 3.5) which is running on the server and I am using that web service in my Windows application. Now I want to replace the web service with WCF service.

To explain this, I will create:

A website with a Default page
A WCF service in it in place of web service

Follow the steps to do this.

Step 1

Add a new website named ‘Wcf_Example’ using 3.5 framework.

Step 2

Add a WCF Service named ‘MYService.svc’ into it.

This will create 3 files:

IMYService.cs – Contains Interface of MYService class
MYService.cs – Contains MYService class
MYService.svc – Contains details required for WCF service to run it successfully like .asmx in web service

Problem

Get the exception when I run the service ‘http://localhost/WCF_Example/MYService.svc'

Solution

Open the control panel and click on ‘Turn Windows features on or off’

Check the ‘Windows Communication Foundation HTTP Activation’ and ‘Windows Communication Foundation Non- HTTP Activation’.

Now run the WCF Service ‘http://localhost/WCF_Example/MYService.svc'.

Remove the Anonymous Authentication Exception in WCF
