C#/.net ActiveDirectory Resources

Question

I have recently assumed maintenance of an app that performs a lot of ActiveDirectory-related tasks, both querying and updating.

I have the existing code to look at of course, but I was also curious if anyone had any good links for AD manipulation through C# and .Net, or pointers to any good books I can convince my boss to buy.

Answer 1

A very good reference: Howto: (Almost) Everything In Active Directory via C#

Answer 2

Linq to Active Directory, baby.

Answer 3

I found this tutorial to be helpful when I got started.
