For those not familiar with the C# programming language

[Astral_Nomad]

I stumbled upon this video series on MSDN. It explains everything basic (fundamental) about how to program in C#. Useful for those that want to get into plugin modding. It uses Visual C# as its compiler. Its a bit outdated (2011), which mean you should probably use the 2010 version of Visual C# to stay with it. I dont know what the results would be with the 2012 version. Full source code for the series is available, and the individual lessons are free to download directly off the site. http://channel9.msdn.com/Series/C-Sharp-Fundamentals-Development-for-Absolute-Beginners Enjoy!

I've been using this, both for KSP and WinPho8 apps, and I agree; it's quite good.

Note that KSP plugins can only target .NET 3.5 or earlier, and that version of the framework was released in 2007. Mind you, a lot of tutorials from 2007 will be for older versions like 2.0 and it would be really bad to learn from those, but you shouldn't feel like you have to keep very up-to-date. Programming languages don't move as fast as other technologies.

Thanks so much for this! I've started it and it's awesome.
