Answer

I thought about reading a KeyPass 2 database so I added a reference to KeyPass.exe in Linqpad and started to experiment. To my surprise and without any outside help (a testament to a good API), I was reading the database after only a few minutes. Here's how I did it:

var dbpath = @"C:\path\to\passwords.kdbx";
var masterpw = "Your$uper$tr0ngMst3rP@ssw0rd";

var ioConnInfo = new IOConnectionInfo { Path = dbpath };
var compKey = new CompositeKey();
compKey.AddUserKey(new KcpPassword(masterpw));

var db = new KeePassLib.PwDatabase();
db.Open(ioConnInfo, compKey, null);

var kpdata = from entry in db.RootGroup.GetEntries(true)
                select new
                {
                    Group = entry.ParentGroup.Name,
                    Title = entry.Strings.ReadSafe("Title"),
                    Username = entry.Strings.ReadSafe("UserName"),
                    Password = entry.Strings.ReadSafe("Password"),
                    URL = entry.Strings.ReadSafe("URL"),
                    Notes = entry.Strings.ReadSafe("Notes")

                };                                                                                  

kpdata.Dump(); // this is how Linqpad outputs stuff
db.Close();
