Hi Guys,
I'm trying to run the MSDN example here http://msdn.microsoft.com/en-us/library/hh228601.aspx and am getting compile errors. I was hoping someone could look at the attached project DataFlowTest.zip and let me know what I'm doing wrong.

Basically it seems that an extension method isn't recognized by the editor.

I get the error:
'OutputAvailableAsync' is not a member of 'System.Threading.Tasks.Dataflow.ISourceBlock(Of Byte())

However, it's there: http://msdn.microsoft.com/en-us/library/hh160369.aspx?cs-save-lang=1&cs-lang=vb#code-snippet-1
And of course, it's used in the MSDN example.

Thanks,
Nick
