Consider the following scenario:

  • You have Microsoft SharePoint Server 2010 Service Pack 2 (SP2) installed in a Windows Server 2012 environment.

  • You create a custom web service by using non-http bindings to SharePoint Server 2010 SP2.

  • You add the custom web service and then try to access it in SharePoint Server 2010 SP2.

In this scenario, you receive the following error message:

Exception: System.InvalidOperationException: The protocol 'net.tcp' does not have an implementation of HostedTransportConfiguration type registered.
at System.ServiceModel.AsyncResult.End[TAsyncResult](IAsyncResult result)at System.ServiceModel.Activation.HostedHttpRequestAsyncResult.End(IAsyncResult result)


This issue occurs because the Microsoft .NET Framework 2.0 Web.config file in Windows Server 2012 is not updated to include the HostedTransportConfiguration TCP connection type.
