Paid Udemy video courses include a certificate of completion when you finish; free courses and practice-test-only courses do not. It shows you did the work, but it is not an accredited qualification. edX usually charges for a certificate, issued with the university or company that made the course. LinkedIn Learning gives a certificate of completion for most of its courses as part of the subscription.

C# Basics for Beginners: Learn C# Fundamentals by Coding (2020)

4.5
(80,103 reviews)
byMosh Hamedani

Mosh Hamedani's five and a half hour intro to C# and .NET, the first of his three-part series, with 284,000 students and a 4.5 rating from about 80,000 reviews.

Best for: People who already know a little programming and want a fast, clear tour of C# syntax before moving on to OOP.

icon
Pros
icon
Cons
    • Explains the why behind each feature, not just the syntax, which one reviewer says most beginner courses skip
    • Short and tightly organized: 87 lectures in about 5.5 hours, with a quiz or exercise after most sections
    • A full section on debugging in Visual Studio, which one student calls the most useful part of the course
    • Leads directly into Mosh's intermediate OOP course, so there is a clear next step
    • Last updated December 2020, so the Visual Studio interface shown does not match current versions
    • Complete beginners say the pace is quick and the exercises jump ahead of what the lectures covered
    • Downloadable solution files lack a .zip extension, and the right project type is only explained in the Q&A

C# Intermediate: Classes, Interfaces and OOP

C# Intermediate: Classes, Interfaces and OOP (2019)

4.6
(41,921 reviews)
byMosh Hamedani

The second part of Mosh Hamedani's C# series, six focused hours on classes, inheritance, polymorphism and interfaces, rated 4.6 by nearly 42,000 students.

Best for: C# beginners who know the syntax but still find classes, inheritance and interfaces fuzzy and want the reasoning behind them.

icon
Pros
icon
Cons
    • Explains why, not just how: encapsulation, composition over inheritance, interfaces for testability
    • Small logical steps that reviewers praise; one says it finally made OOP make sense
    • Six hours and 44 lectures on one topic, with no detours into unrelated material
    • Ends with three code reviews of real student submissions
    • Last updated in October 2019; the Visual Studio on screen looks dated and the Q&A is quiet
    • No quizzes or coding exercises built in; several reviewers wanted more practice
    • Some students found the interfaces section too short on when to actually apply them

Basics of Object Oriented Programming with C# (2020)

4.5
(6,332 reviews)
byTod Vachev

A free 100 minute primer on classes, properties, constants and enums in C#, capped by a small Warrior Wars game that shows how the pieces fit together.

Best for: People who already write some C# and want a short, free refresher on classes and properties before tackling a longer OOP course.

icon
Pros
icon
Cons
    • Covers classes, properties, const vs readonly, statics and enums in under two hours, for free
    • The Warrior Wars project ties the concepts together in working code rather than slides
    • Reviewers say the explanations are brief and clear, and one says the project showed why the code was built that way
    • About 81 percent of the 6,300 plus ratings are 4 or 5 stars
    • Pace is fast, especially in the project, and several reviewers wanted fuller explanations
    • Not truly All Levels: it needs prior coding and some C#, and beginners say it assumes too much
    • Inheritance, interfaces and polymorphism are not on the syllabus, and the last update was September 2020

Complete C# Masterclass (2025)

4.5
(37,917 reviews)
byDenis Panjuta

A long, beginner-friendly C# course that goes from variables to OOP, then builds WPF desktop apps with a database and LINQ, though reviewers say it gets rushed in the second half.

Best for: Windows users starting C# from zero who want to end up building desktop apps with WPF and a database.

icon
Pros
icon
Cons
    • Early sections are easy to follow, and one reviewer liked how code is explained by stepping through the debugger
    • Covers loops and OOP through events, delegates, LINQ and SQL Server databases in one place
    • A three-part WPF currency converter gives beginners a real desktop app to build
    • Very well rated: 21,950 five-star and 12,268 four-star ratings from 37,917 reviews
    • Reviewers say the second half feels rushed and less detailed than the first
    • WPF and database sections need Windows, and one reviewer found a later chapter outdated
    • Coding exercises and some articles draw criticism, and reviewers want bigger projects

The Ultimate Guide to Game Development with Unity (Official) (2025)

4.7
(20,844 reviews)
byJonathan Weinberger

The only Unity-authorized beginner course on Udemy, teaching C# through a 2D space shooter and a 3D stealth game, with a big catch: much of the footage is old.

Best for: Complete beginners who want to learn C# by building a 2D shooter and a 3D stealth game, and can cope with fixing version gaps.

icon
Pros
icon
Cons
    • Weinberger explains the reasoning behind the code, not just the keystrokes, and reviewers say the pace suits newcomers
    • Challenges ask you to attempt a solution before the answer is shown, so it's not pure follow-along
    • Three projects, including a 3D stealth game with cutscenes and enemy AI, not just a single 2D demo
    • Active Discord where reviewers say they get fast help with version problems
    • Large parts of the footage use old Unity versions; reviewers report broken asset imports and failed Android builds
    • No section on setting up Visual Studio with Unity, and several reviewers hit tooling mismatches early
    • The third project, the 2D mobile dungeon game, is only a handful of lectures in the syllabus

A dense, demo-driven walk through SOLID and every Gang of Four pattern in C#, with modern variations, aimed at developers who already write solid C#.

Best for: C# developers with real experience who want every GoF pattern plus its modern variations, shown as live code.

icon
Pros
icon
Cons
    • Covers SOLID plus every Gang of Four pattern, with 23 coding exercises to practice on
    • Shows static and dynamic variations of patterns, not just the textbook versions
    • Reviewers call the explanations very detailed, with plenty of hands-on C# code
    • Taught by a C# MVP since 2009, so the language-level depth is real
    • Many examples are shapes, people and in-memory databases, not realistic business cases
    • Several reviewers find the pace fast and some implementations overcomplicated for simple ideas
    • Little on .NET-specific or ASP.NET Core use of patterns despite the title

As the name implies, this Channel 9 course is intended to be a first-ever experience with C#. It is split into 25 separate video lessons and covers topics ranging from an introduction to C# to utilize namespaces and .NET.
icon
