For those interested in ADSB#, I believe it was renamed ADSB Spy and is now included with SDR# available at airspy.com. SDR# has a bit of a messy history and at one time was completely open source but was later closed after some dispute between the developers (to the best of my knowledge). If you look hard enough you can still find the source code of the older versions of SDR# and ADSB# which is handy if you want to learn how they work, although its all C# .NET and there is some wild stuff going on to try and squeeze enough performance out of the code. This is where I started learning though being a .NET developer, and from there moved on to GNU Radio and now learning C++. Fascinating subject.
