When you call db.SubmitChanges(), does it only generate the SQL statement to update the column [UnitsInStock], or will it update all columns?

If only [UnitsInStock] is updated, how does the compiler/runtime know that only this field has changed? (since it is a field, and not a property with a set accessor)

Could you clarify something? According to the description under "C# LINQ Tech Preview" on http://msdn.microsoft.com/netframework/future/linq/, it says "Note: this preview works only with the Visual Studio 2005 Release Candidate." We received the RC version at PDC. However, after installing RC and this LINQ Tech Preview from the web (not the one on disc 4), my LINQ projects don't work anymore.

To confuse matters even more, I found this snippet in C:\Program Files\LINQ Preview\Docs\ReadMe.htm: "The prototype compilers and samples will not function on builds later than Beta 2. Note that this means you must not be running the RC0 build of Visual Studio included in the PDC kit."

So, should I just go back to Beta 2, or will there be an update for the LINQ preview soon?

Thanks,
Dan Miser

I tried commenting before, and it didn't take. You might want to take a look at this link for some problems with the deliverables:
