I have just released a completely free online course on the C# language. This course used to sell for $99 but from today you can sign up for free. It contains 33 video lessons (over four hours of instruction) pus an eBook and all the source code of the sample projects. Sign up here: https://bitwisecourses.com/p/learn-to-program-csharp
If you want to get started with C# programming on Windows (using a free copy of Visual Studio), this is the course you need!
Incidentally, if you prefer to learn from a book or you need a book to take you deeper into the subjects covered in my course, my book, The Little Book Of C# is available in paperback or for Kindle on Amazon (US) https://amzn.to/2JWDI0o, Amazon (UK) https://amzn.to/2YaCPtS and worldwide.
