When i try to build the DcmAssignBaseline code sample that comes with the Microsoft System Center 2012, I get: "Error 5 The type or namespace name 'ConfigurationManagement' does not exist in the namespace 'Microsoft' (are you missing an assembly reference?)" - and several other errors. 

The referenced error is tied to the line: using Microsoft.ConfigurationManagement.ManagementProvider;

I tried to add the reference (Solution Explorer/References/Right click/Add Reference), but there is no "Microsoft.ConfigurationManagement" reference available to add.

Any help would be appreciated.

Ok, solved the problem (I could delete this, but possibly someone else might have the same issue).

My Microsoft Configuration Manager was on a remote machine.  Had to navigate to that device and then to:  C:\Program Files (x86)\Microsoft Configuration Manager\AdminConsole\bin.  The two needed DLLs were there.  (I did have to copy them to my development area) then:

Solution Explorer/DcmAssignBaseline/References/
Right click: Add Reference

Added: AdminUI.WqlQueryEngine.dll (and) Microsoft.ConfigurationManagement.ManagementProvider.dll
