Error in Protocol Mapping While hosting a WCF service in IIS

Question

I developed a simple WCF service with VS 2010. And i hosted in the default website in IIS by Adding Application and set the Physical Path

And i tried to browse the .svc file it gives me the following error:

"The configuration section 'protocolMapping' cannot be read because it is missing a section declaration"

and I tried many solutions but it doesn't work

I Created WCF Service Library has an App.config with this:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>

  <appSettings>
    <add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
  </appSettings>
  <system.web>
    <compilation debug="true" />
  </system.web>
  <!-- When deploying the service library project, the content of the config file must be added to the host's 
  app.config file. System.Configuration does not support config files for libraries. -->
  <system.serviceModel>
    <services>
      <service name="EvalServiceLibrary.EvalService">
        <clear />

Amr,

This sounds like you may have permission issues in the folder you .svc is running from, please can you check and see if the following permissions are there:

• \IIS_IUSERS
• \IIS_IUSR ---If running webservice in Anonymous Mode

For the issue with protocol Mapping, please ensure that the app Pool you are using for the IIS site is setup to use .net 4, as from what I understand protocol mapping is only available in .net 4.

Hope this helps
