WMI Query to SCCM 2012 results zero results in c#

Question

In 2007 this works without issues, however in 2012 when attempting the 2nd query it returns zero results.  However if I do this manually I can produce results...Here is my code:
using (WqlConnectionManager connection = Connect(getServer))
   string query = "select * from SMS_ObjectContainerItem WHERE ContainerNodeID='" + ProfileID + "'";              
   foreach (IResultObject getobject in connection.QueryProcessor.ExecuteQuery(query))
     getPackageID = getobject["InstanceKey"].StringValue;
     query = "select * from SMS_Collection WHERE CollectionID='" + getPackageID + "'";
**This is where it will return zero results**
     foreach (IResultObject searchID in connection.QueryProcessor.ExecuteQuery(query))
        CMProfiles profile = new CMProfiles();
        profile.Name = searchID["Name"].StringValue;
        profile.ID = getPackageID;
        results.Add(profile);
I'm pulling my hairs trying to understand by the 2nd query is not returning any results. When this works fine in SCCM 2007

What you are using here are the SDK libraries, which are admittedly very thin wrappers around WMI, but not quite.  Have you tried implementing this directly using WMI?  I have written software that manipulates 2007 / 2012 and eventually found that
the SDK libraries just sort of got in my way, so now I do all of my interactions with SCCM directly with WMI and forgoe the SDK libraries.
Before I changed over, I did find that there are some oddities in using the SDK.  What I eventually found that worked for me was to bind to the 2007 SDK libraries, deliver them with my application and use the 2007 libraries regardless of if I was connecting
to 2007 or 2012.  What I found was that I would run into issues using the 2012 libraries to talk to 2007, but the 2007 libraries would work fine with both.
I have tested your queries, directly using WMI and PowerShell on a 2012 server and they work fine.  I am presuming that the folder that you are attempting to access is a Device Collection folder.
Once again, I would suggest using WMI directly, especially if making a product that will work with 2007 and 2012; you will be a much happier person.
