After installing the hotfix:;en-us;2300488

My Synchronization connection to the AD cannot be populated, because I get a "Method not found" exception:

Method not found: 'Int32 Microsoft.Office.Server.Administration.UserProfileApplicationProxy.get_LdapConnectionTimeout()'.

It looks like an inconsitency, between different parts of the SharePoint installation, where the proxy class does not contain the requested property. To confirm this claim, I ran from powershell:

// after mounting the SPServiceApplicationProxy class in a variable $proxy....
$proxy | Get-Member

It returns a reflection of the object - a list of properties and methods, and yes... there is no LdapConnectionTimeout.
