Installation notice for the SharePoint Server Public Beta on Microsoft Windows Server 2008 R2 and Microsoft Windows 7

 

Installing the SharePoint Server 2010 Public Beta on Microsoft Windows Server 2008 R2 or Microsoft Windows 7, then you will need to download and install an update from http://connect.microsoft.com/VisualStudio/Downloads/DownloadDetails.aspx?DownloadID=23806  to resolve an issue that occurs in Microsoft SharePoint Server 2010 when provisioning Service Applications or when accessing pages that make service calls.  Without the hotfix, these operations will result in an error "System.Configuration.ConfigurationErrorsException: Unrecognized attribute 'allowInsecureTransport'. Note that attribute names are case-sensitive. (C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\WebClients\<Service Area>\client.config line <Line Number>)".
