-
- Four playable 2D games, each its own section, so progress shows quickly

- Discord and Q&A support that reviewers describe as helpful
- Being remastered for Unity 6, last updated July 2026, with the older material still included

C# Basics for Beginners: Learn C# Fundamentals by Coding (2020)
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.
-
- 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
3
Complete C# Unity 3D Game Development in Unity 6 (2026)
Five finished 3D games, from a simple dodge game to a first-person shooter, teach C# and Unity 6 from zero in about 27 hours, with the content refreshed in 2026.
Best for: Complete beginners who want to learn C# by shipping five small 3D games rather than reading about classes first.
-
- Challenge-then-solution format: one reviewer was solving problems before the instructor posed them
- Short, focused lectures (192 over 27 hours) that reviewers say are easy to follow
- Covers real systems: nav mesh AI, raycasting, object pooling, procedural generation, ProBuilder
- Rick Davidson's opening sections explain everything from the ground up, per beginner reviews
-
- Second instructor Stephen Hubbard moves fast and often skips the why, a common complaint from beginners
- One 3-star review flags a distracting mouse-spinning habit; another says subtitles sometimes fail to load
- Breadth over depth: a 4-star review says it gets your feet wet but is not enough to master
4
C# Intermediate: Classes, Interfaces and OOP (2019)
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.
-
- 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
5
Basics of Object Oriented Programming with C# (2020)
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.
-
- 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
6
Complete C# Masterclass (2025)
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.
-
- 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
7
C# Advanced Topics: Prepare for Technical Interviews (2019)
What You'll Learn
- Understand advanced C# features and apply them at work
8
The Ultimate Guide to Game Development with Unity (Official) (2025)
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.
-
- 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
9

-
