Up/Down Nodes: Visual C#

Problem this snippet solves:

This app enables and disables nodes. It installs and runs as a stand alone windows application. It connects to an LTM, collects the pools, collects pool members, and allows the user to toggle the enabled/disabled state of nodes.

This is my first iControl App. It is also my first run at C# and Visual Studio. It is pretty basic and a little rough around the edges. I am posting it because I did not find many examples of C# using Visual Studio. I plagiarized from other code examples found on DevCentral so you may see some similarities if you look around.

The entire project is attached as a .zip.
