I created and deployed a pretty simple WCF Service. but when accessing it from IE, I get this :

HTTP Error 500.19 - Internal Server Error
Description: The requested page cannot be accessed because the related configuration  
data for the page is invalid.

More Information... This error occurs when there is a problem reading the  configuration file for the Web server or Web application. In some cases, the event logs  may contain more information about what caused this error.

here is the content of my web.config file :

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <configSections>
        <section name="dataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings, Microsoft.Practices.EnterpriseLibrary.Data, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
    </configSections>
    <dataConfiguration defaultDatabase="AdventureWorksConnection" />
    <connectionStrings>
        <add name="AdventureWorksConnection" connectionString="Database=AdventureWorks;    Server=(localhost)\SQLEXPRESS;Integrated  Security=SSPI"
            providerName="System.Data.SqlClient" />
    </connectionStrings>

  <system.serviceModel>
    <services>
      <service name="Products.ProductsService">
        <endpoint address=""
        binding="basicHttpBinding"
        contract="Products.IProductsService" />
      </service>
    </services>
  </system.serviceModel>

</configuration>

I believe your IIS doesn't know about the .svc files yet - see this blog post for more info and explanation how to fix that: rogerpence.com/blog/?p=280 — marc_s

Well, it looks like your service exposes no metadata exchange at all - you'll need to add at least the serviceMetadata behavior so that clients can inquire about the service's metadata, and if you want to be able to retrieve that using a browser, you'll also need to enable the httpGet on that serviceMetadata behavior:.

Extend your web.config like this:

  <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior name="Metadata">
          <serviceMetadata httpGetEnabled="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <services>
      <service name="Products.ProductsService" behaviorConfiguration="Metadata">
        <endpoint address=""
        binding="basicHttpBinding"
        contract="Products.IProductsService" />
      </service>
    </services>
  </system.serviceModel>
