One more piece of information. Using the process explorer the counts for generation 0,1,2 heaps are the follow
Gen 0 heap size 5,242,880
Gen 1 heap size 22,940
Gen 2 heap size 1,348,823,532
Large Object Heap Size - 318,120,552
It does look like a memory leak in the console part of the app.
I can email you the project if that would help.
