Hi,

Now studying disconnected state, found a strange behavior (which I'm trying to believe is my mistake but I can't find it. Here's the piece of code:

foreach (Item anItem in Collection.Where<Item>((item => item.Entity1.Equals(anEntity1) && item.Entity2.Equals(anEntity2))))

In this snippet, "Collection" is an EntitySet<item>. The method with this code is being tested by standard MSTest tests.

The above snippet will work (i.e. it will correctly find the items in Collection matching the criteria) if I'm working in standard mode with DO4.

When I'm working in Disconnected State, even inside a .Connect() using block, it won't work the same despite the fact that "Collection", "anEntity1" and "anEntity2" have the exact same state than when in "Connected Mode".

The really weird behavior is that a simple change in the snippet above seem to fix everything in disconnected mode:

foreach (Item anItem in Collection.ToList().Where<Item>((item => item.Entity1.Equals(anEntity1) && item.Entity2.Equals(anEntity2))))

The simple fact that I generate a list from the EntitySet before applying the .Where extension, seem to fix the issue.

Am I missing something really obvious here? Or is this truly strange?

Thanks!
