Requirements

No programming experience needed.
Passion and perseverance for computer science

Description

If you want to develop a thorough understanding of:

why you should choose .Net as a platform and C# as the main programming language for your applications;
the ideas behind namespaces and their practical use in project dependency situations;
the fundamental building blocks of every programming language;
how are variables saved in the memory and why this is important to know;
the intricacies of the types string, list and dictionary;
the logic behind the creation, the advantages and the uses of methods/functions;

then you are at the right place.

The detailed explanation of concepts (it doesn't matter how simple or complex they may seem) coupled with real-life examples and exercises to be solved are vital for the students' educational progress. Finding the balance between the new and the practical piece of that information is a tough challenge for the instructor because he needs to justify why and when that knowledge will be used without the students feel overwhelmed by the learning process.

Before we start making multi-tier applications a strong foundation of knowledge, skills and experience with solving simple tasks are necessary. This course is the first stepping stone towards achieving that goal.

I hope that my students will be benevolent toward each other in the Q&A section of the courses and be successful in their future career as a software developer (and engineer). No previous experience is required. Only passion and perseverance for computer science.

Who this course is for:

Complete beginners who want to learn C#
Anyone who has an interest in software development
