I would also consider InvokeRequired (VS2008 only) when calling Invoke. There are times that you will not be updating the UI from a seperate thread. It saves the overhead of creating the delegate etc.

            //This.Invoke added to circumvent cross threading exceptions.
            this.Invoke(new UpdateProgressBarHandler(UpdateProgressBar), new object[] { progressPercentage });
        }
        else
        {
            UpdateProgressBar(progressPercentage);
        }
