One problem I've run into is that by default, the framework runs in 64-bit
mode. This can cause silent failures if you're calling 32-bit dlls in your
code (e.g., via interop). There's a compiler switch that you can set to
force 32-bit mode:
/platform:x86 (http://msdn2.microsoft.com/en-us/library/
My advice is to always start with the simpler choice - List in this case,
and only switch over if you find that you need more performance in that area.
I wrote some more on that subject here:

Have you thought about graying it out using opacity? If you set the opacity to
about 50%, you will likely get the effect that you want. You can control how it
grays by putting a rectangle of the appropriate color (white, black, gray)
directly behind the image...

vast differences in access
time between cache, main memory, and disk can easily overshadow raw code
speed.
My advice is to write code as simply as possible, use TDD so that you
have unit tests and can therefore refactor as needed, and *measure* your
performance early and often.

Ack, sorry... actually, you just need to change the return type to Guid.
Out of curiousity, why is this a generic function at all? You never use T at
all except as the return type, and that's constrained already by the type of
QuestionElement.Uid (which appears to be Guid)...

It sounds like you want to use a mock object pattern.
A java example is

technique obviously applies elsewhere.

A couple of ideas:
1) If you are already using a windows form, you can easily add a windows
forms timer to your form. That timer occurs on the main UI thread, and
can easily be used for update.
2) If you want to stick with the Timer you're using, you need to call
Control.Invoke() (not BeginInvoke
Depending on the requirements of your win32 dll, you may be able to use
MC++ to accomplish what you want.

Your talking at the time of the install? TARGETDIR is what the user selects
as the directory to install the app.

I should probably note at this point that "where" is a contextual
keyword - the same as "get", "put", and "value". All the enhancements
we're doing in 2.0 use contextual keywords (though the PDC bits use
yield, which is non-contextual, and will change to "yield return" in the
final version).

Peter,
You can get into some conflicts sometimes if you have namespaces names
that match class names or other namespace names. We do plan on providing
a way to avoid having to use aliases in Whidbey, but in general, I think
it's best to try to avoid name collisions.

My guess is that they it's scaled because it's fairly easy to tell
people that they should use a load factor between 0 and 1. If the load
factor ranged between 0 and 1 but the best value was 0.72, somebody
would pass in something like 0.90 and then have problems when their
hashtable didn't work.
I haven't read Don's book, but I think he's comparing:
If (obj is Employee)
{
Employee e = (Employee) obj;
}
To
Employee e = obj as Employee;
If (e != null)
{
//...
}
In the first case, there are two tests (on at the is, and one on the
cast), and on the second, only a single test.

There's no way to do what you want in C#.
You could, however, write a wrapper in MC++ and then use the wrapper
from your C# code.
