This course will start with the explanation of the intricacies between out, ref and in keywords. Then the students will learn about new data types (tuples and structures) – when and why they should be used. After grasping all of the preceding knowledge, there shall be no mistakes when students use value or reference types. The late-bounding (enabled by various techniques of polymorphism – inheritance, object, dynamic, generics and reflection) opens new doors that will be explored in this course in theory and practice.
The topics about delegates and events are very interesting and usually difficult for new developers. The concept of holding a reference a method is something common to functional programming, but C# allows you to get the advantages of that feature too. The students who will finish this course won’t have problems understanding when and how to use delegates. The Event-driven Design (EDD) is based on the work with events and delegates (wired to them). Coupling EED with the knowledge and characteristics of OOP will help students build web, mobile and graphical applications in the near future/courses easily.
The last two important concepts that will be taught in this course are lambda expressions and LINQ. Understanding how they work will improve not only the development speed of different tasks/algorithms but will give the students opportunity to grasp the clever use of delegates, generics and the so called ‘Fluent API’ – a technique that will be used later (when we separate and specify our components/libraries of the n-tier application and/or use ORM such as EF Core).
Before we start making multi-tier applications, a strong foundation of knowledge, skills and experience with solving simple tasks is necessary. This course is the third 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 careers as software developers (and engineers).

Greetings, stranger! :) I am not surprised to see your kind here. If you want to break free from the Singleton pattern and the exceptional thought about learning from more than one teacher pops up in your mind stack, then you better try that idea now, before the memory reallocation takes place. Some say that in order to become a great software developer you shall learn from the start. The mighty and fearsome kung-fu legends of the past talked and taught about the importance of a strong foundation. In their case that was the core and the legs, in our case, that’s the fundamental theory that will allow us to build complex and meaningful applications.
But don’t be fooled by the seemingly simple task – the casting of that theory into practice will have its price – the asynchronous 0s and 1s that will create the never-ending illusion of everything. The battles ahead will contain different data types, complicated concepts, composite layers of business logic, a variety of databases, and on top of that a selection of presentation layers for the different tastes of the end users. If you are intrepid and passionate enough, merciful and generous towards my lack of ‘x’ years in renowned universities and companies – you have the basic requirements and I am thankful. I will do my best so you can become what I am not – a better version in that repository! :)
P.S.: If you enjoy playing computer games like Witcher 3, WarCraft 3 TFT, Heroes 3 Might and Magic, AOE 2/3, and Diablo 2 – congratulations, you met the recommended requirements for my courses. :)
P.S.S: I have been teaching professional classes in Software Development for 5 years and have a Bachelor's degree in Business Information Technology.
