Adding Tracer To WCF Service

Question

I'm trying to add a tracer to the WCF service messages using this configuration data I added the tracer using SvcConfigEditor.exe and here's the web.config generated file out of it

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

        <filter type="" />
      </add>
    </sharedListeners>
    <trace autoflush="true" />
  </system.diagnostics>

</configuration>

but when I try to run the WCF test client I get the following exception

The requested page cannot be accessed because the related configuration data for the page is invalid.

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

I really have no idea why it's throwing this exception

Answer 1

Because entityFramework tag is non-standard for .NET. You need to tell it how to interpret it.

In order to do that add following section to your file (e.g. before <connectionStrings> one:

<configSections>
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
</configSections>
