PowerShell API for ADFS 3.0

Hi, we used to use PowerShell APIs in our C#.NET application to automate the ADFS configuration, e.g. using classGetAttributeStoreCommand (this class is in Microsoft.IdentityServer.PowerShell.dll) to get sttribute store. That worked fine for ADFS 2.0. Recently we upgraded our system to ADFS 3.0. The application does not work anymore. The application cannot findMicrosoft.IdentityServer.PowerShell.dll. After enable the ADFS role in Windows Server 2012, I cannot locateMicrosoft.IdentityServer.PowerShell.dll. I searched the whole machine, it is nowhere to be found. Seems this dll is never installed with ADFS 3.0. So isthis dll (and Name SpaceMicrosoft.IdentityServer.PowerShell.Commands) still available in ADFS 3.0 ?

Thanks
