Introduction1:33
Instructor Bio1:04
Using Udemy Code Exercises14:38
This lecture explains how to use the Udemy Code Exercise feature to get the most out of your training experience.
Note - See the next lecture - Lab Alternatives for a better option for labs. Rather than using the built-in Udemy code exercise mechanism, the Local labs are set up for use on a local Visual Studio environment. I strongly recommend local labs rather than the Udemy Code Exercise feature.
Lab Alternatives2:22

Exceptions14:09
At the end of this lecture and lab, you will have a firm grasp of exceptions.

Inheritance Part 3 - Polymorphism12:51
Inheritance Lab3 - Template Method
Local Coding Exercise - Inheritance Part 3 - Template Method0:57
Inheritance Lab 3 Review0:45
Interfaces10:40
An interface is a lightweight type. The design of an interface is driven by the caller, which is very different from the drivers of inheritance design.
At the end of this section, you will have a new understanding of interfaces.
Interface Lab
Local Coding Exercise - Interfaces0:27
Interfaces Lab Review0:49
Generics18:53
Generics let us write typesafe code in a way that doesn't create a lot of dependency. At the conclusion of this topic, you will be able to create and use generics.
Generics Lab
Local Coding Exercise - Generics0:16
Generics Lab Review0:34
Tuples11:28
Whether it's tuples or tulips, this is a fun topic that will explain how a lot of syntax that you will see in C# really works!
Operator Overloading13:44
A good citizen of C#land will implement some operators. At the end of this topic, you will know how to make your classes robust with operators.
Operator Overloading Code Exercise
Local Coding Exercise - Operator Overloading0:11
Operator Overloading Lab Review0:32

Class Object18:31
Object is the root of all classes. A robust class in C#land will override some methods from Object. At the end of this topic, you will know how to make your classes great!
Overriding Object Methods Code Exercise
Local Coding Exercise - Overriding Object Methods0:14
Overriding Object Methods Lab Review0:39
Collections9:30
Collections are great. This topic will familiarize you with collections.
Collections Code Exercise

Collections Lab Review0:24
Dates & Times12:20
Does anyone really know what time it is? Does anyone really care? After this you will know how to use localized dates and times!
Extension Methods5:37
Extension methods let you add methods to existing classes. Find out how by watching this lecture and completing the code exercise!
Extension Method Code Exercise - String.IsMatch
Local Coding Exercise - Extension Methods0:17
Extension Methods Lab Review0:12

Delegates12:34
No, you cannot delegate this topic to someone else!
Delegate Lab
Local Coding Exercise - Delegates0:40
Delegates Lab Review0:52
Events5:41
A paranormal event is when your instructor pops out of thin air. A C# event is a multicast delegate. Learn about the power of events with this lecture and lab.
Events Lab
Local Coding Exercise - Events0:32
Events Lab Solution0:09
This lesson provides the solution for the Events lab.
Lambda Expressions7:25
I love lambas. You will too after this lecture! Note, I attached a solution to the event code exercise to this lecture.
Lambda Lab
Local Coding Exercise - Lambda0:30
Lambda Lab Review0:03
Language Integrated Query (LInQ)15:51
Language Integrated Query is one of the most powerful tools in .Net. After this lecture, you will have a practical knowledge of LINQ. Check out the PDF in the downloads. It covers some of the most common delegates used by LINQ.

Introduction to C#
Experience in other curly braced languages like C++ or Java

Description

This intermediate‑level course is designed for developers who already understand the basics of C# or have completed your introductory course. It teaches the real‑world skills needed to become a professional C# developer, with a strong focus on object‑oriented design, clean architecture, and modern .NET development practices.

You’ll learn how to design and implement classes, handle exceptions correctly, apply inheritance and polymorphism, work with interfaces, and build reusable components using generics. The course also covers delegates, events, lambda expressions, LINQ, reflection, metadata, threading, tasks, and essential features of the .NET library.

Chuck’s courses have been used by Microsoft to train their own developers and have been delivered to thousands of engineers across corporations, government agencies, and the military. His teaching style emphasizes clarity, best practices, and hands‑on learning through interactive labs and assignments with instant feedback.

By the end of this course, you’ll have the confidence and skills to build robust, maintainable, object‑oriented applications using modern C# and .NET.

What You’ll Learn

Design and implement classes with constructors, inheritance, and polymorphism
Handle exceptions correctly and build robust error‑handling strategies
Apply interfaces and dependency inversion for clean architecture
