PC side WinUSB Bulk Example in C#

FYI, googling for "C# WinUSB" turned up a very nice bit of C# example code which shows how to use the WinUSB driver, posted by Jan Axelson on his web site, www.lvr.com. I tried it and was able to talk to my LM3S3748 running the usb_dev_bulk code. Just had to change the GUID in Jan's code to match the GUID in the Luminary inf file. Jan did all the P/Invoke Interop stuff and got it working. Thanks, Jan, for sharing.
