If you're on 2.0 doing SQL work, you should definitely read
up on the async
support that was introduced (SqlCommand.BeginExecuteXxx).
Related to that
is the SynchronizationContext/AsyncOperation stuff that was
introduced as
well. For a quick intro to the async SQL stuff, you can
start with one of
my blog posts[1] (from Nov of 2005). You'll also find some
other stuff in
the Oct & Nov 2005 area of my blog. If nothing else,
you'll see a bit of
sample code and discover the names of some types/methods you
can read up on
in MSDN and/or google around for.
On the async i/o and sockets front, I've got a sample over
here[2] that
demonstrates async I/O and incoming connection accept on the
1.1 runtime.
That particular app doesn't do anything other than let me
see how many idle
connections I can handle on a given machine (as well as how
to deal with
multithreaded access to Windows Forms controls in a safe
fashion). But
there's some sample code value there...
