Code Forward: Level Up in C# Step by Step

About Course

If you’re just starting out on your programming journey, C# is a great choice as your first programming language. The popularity of C# is explained not only by the fact that it is easy to learn, but also by the real advantages of the language in terms of its professional use for solving complex automation problems. C# is a cross-platform language and programs written in it run under Windows, Linux, Mac OS. It has a concise and elegant syntax. A huge number of ready-made libraries makes it possible not to reinvent the wheel at every step.

This course covers all the basic features of C# and provides guidance on writing competent, “clean” code.
