title: Can I run a .NET 2 application below a .NET 4 website with multipleSiteBindingsEnabled
body: <p>I have a website with an app pool running .NET 4 on IIS 7 and it has the following setting in system.ServiceModel in the Web.config:</p>
  
  <pre><code>serviceHostingEnvironment multipleSiteBindingsEnabled="true"
  </code></pre>
  
  <p>The problem I have is that I want to be able to run an application below this using a .NET 2 app pool. When I try this the app complains that it has an unknown attribute for multipleSiteBindingsEnabled. I can't see a way to hide this .NET 4 attribute in the Web.config of the .NET 2 application. Is there any way to do this?</p>
