Restful WCF 4.0上的IIS 7.5错误

Question

I've been trying to do a simple restful wcf service that will return JSON. Its working if i will run it in the development server. However if I deploy it on IIS 7.5, i will have this error when i accessed it using http://localhost:70

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

Config Error The configuration section 'standardEndpoints' cannot be read because it is missing a section declaration

Here is my configuration file: This is the default file generated by the VS2010.

<?xml version="1.0"?>
<configuration>

  <system.web>
    <compilation debug="true" targetFramework="4.0" />
  </system.web>

  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true">
      <add name="UrlRoutingModule" type="System.Web.Routing.UrlRoutingModule, System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
    </modules>
  </system.webServer>

  <system.serviceModel>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>
    <standardEndpoints>
      <webHttpEndpoint>
        <!-- 
            Configure the WCF REST service base address via the global.asax.cs file and the default endpoint 
            via the attributes on the <standardEndpoint> element below
        -->
        <standardEndpoint name="LocationService" helpEnabled="true" automaticFormatSelectionEnabled="true"/>
      </webHttpEndpoint>
    </standardEndpoints>
  </system.serviceModel>

</configuration>

Im new to WCF specially on .net 4.0 and IIS 7.5.

Can anybody help? Or anybody has experienced the same and has fixed already?

Answer 1

Do you definitely have the IIS application pool for your site configured to run with ASP .NET 4.0?

Right click your Virtual Directory in IIS Manager > Manage Application > Advanced Settings > read the app pool name.

Then go to Application Pools, find that name and make sure the .NET Framework column says v4.0.

Answer 2

I had the same error on a w2008 x64 with the app pool running .net 4.0; after installing SP2 the issue disappeared

Answer 3

This issue can be seen on Windows Server 2008 without service pack 2 installed. To fix the problem install Windows Server 2008 Service Pack 2.

Taken from Ram Poornalingam's WebLog entry from the 26th October 2009 :

If you encounter the following error in your web application (things hosted in IIS) “The configuration section cannot be read because it is missing a section declaration"

examples

“The configuration section 'standardEndpoints' cannot be read because it is missing a section declaration”

“The configuration section 'tracking' cannot be read because it is missing a section declaration”

then you need to install either SP2 of Vista/Win2k8 or the hotfix mentioned in KB article 958854.

Answer 4

Sorry to ask a question that may seem obvious to some, but it might help others (mainly me) if you could clarify the last step:

Then go to Application Pools...

Where do I find Application Pools ?

If you can't tell I am used to working for big companies where someone else did that for me and now I am playing developer and IT director.

Thanks

Ok, after 10 seconds of research (I opened my eyes) and looked right above Sites in IIS Manager
