ObjectType is obsolete

[some-1-2]

I have this part of the code:

FamilySymbol fs = list[0].ObjectType as FamilySymbol;

which is throwing a warning in my compiler saying

[Warning 2 'Autodesk.Revit.DB.Element.ObjectType' is obsolete: 'Use Element.GetTypeId() and Element.ChangeTypeId() instead.' G:\ProjectX\Tool\FormPanelArea.cs 166 28 ProjectX]...

This is a project C# file that I got from the SDK samples [[…\Revit2011SDK\Software Development Kit\Samples\Massing\MeasurePanelArea\]

I am wondering if the warning message is showing up because there are changes in API from revit 2010 to 2011.

Thank you

Yes, you'll find that the 2011 API has significant changes over the 2010 API.

I have also had the same problem when copying the Material Properties "example". It does not work and I get the same error message. I have tried every permutation of syntax but I have hit a brick wall. Has anyone ou there got the correct replacement syntax for

Dim type As Autodesk.Revit.DB.ElementType = elem.ObjectType
