Image recognition puzzle: Which off-the-shelf WPF library is this program using for its GUI?

I'm really curious to know which off-the-shelf WPF library this program is using for its web interface.

I'd like to use a few of the components in a small, in-house .NET program I'm writing.

Here is a couple of images showing the program in question (and if you d开发者_运维百科on't know what WPF library this one is based on, please feel free to recommend your favourite).

Get a copy / trial. Look at the dll's downloaded. Third party components have very recognizable names (after all there are only some players there anyway).
