INTRODUCTION

This hotfix provides the following features for Windows Communication Foundation (WCF) in the Microsoft .NET Framework 3.5 Service Pack 1 (SP1) on a computer that is running Windows 7 or Windows Server 2008 R2. This hotfix is also a prerequisite for Microsoft Office SharePoint Server 2010.

Feature 1

The hotfix adds the AllowInsecureTransport property in the SecurityBindingElement class for the .NET Framework 3.5 Service Pack 1. The default value of this property is set to False. When the property is set to True, the mixed-mode secured message can be sent over an unsecured transport such as HTTP in Windows Communication Foundation (WCF) services. The property should be set to True only when the client and the service are in a trusted environment.

Feature 2

WCF services in the .NET Framework 3.5 Service Pack 1 use only a single thread to receive secure messages, even if SharePoint has multiple Web services concurrently receiving requests from different service clients.This hotfix adds DispatcherSynchronization endpoint functionality to improve the performance of the SharePoint services that use WCF. This endpoint functionality lets you use multiple threads in a service instance to concurrently receive secure messages.

Feature 3

This hotfix provides access to the OutgoingSupportingTokens property in the SecurityMessageProperty class. SharePoint Web service clients can use this new property to reduce the average latency of client-side requests by reusing tokens when they are required. Previously, tokens were regenerated for each request.

Prerequisites

You must have the .NET Framework 3.5 SP1 installed to apply this hotfix.

Restart requirements

You do not have to restart the computer after you install this hotfix if there is no .NET Framework instance currently being used.

Examples of the new features

The following code example shows how to use the AllowInsecureTransport property in the security configuration of a custom binding.

<customBinding>   <binding name="SampleHttpBinding">      <security           authenticationMode="IssuedTokenOverTransport"           allowInsecureTransport="true"/>       <binaryMessageEncoding/>           <httpTransport/>   </binding></customBinding>

The following code example shows how to use the DispatcherSynchronization endpoint behavior to specify the maximum number of threads for receiving messages.

<services>      <service name="MicrosoftMyTestService">        <endpoint address="http://loocalhost/IService" binding="customBinding"                  contract="IService"                  behaviorConfiguration="ServiceEPBehavior" bindingConfiguration="MyCustomBinding">        </endpoint>      </service>    </services>    <behaviors>      <endpointBehaviors>        <behavior name="ServiceEPBehavior">          <dispatcherSynchronization maxPendingReceives="10"/>         </behavior>      </endpointBehaviors>    </behaviors>
