Pure C#, no JavaScript required. Video lessons, references, graded quizzes and live coding labs — plus an AI Coding Exercise in every course, where you brief ChatGPT or Claude, review what it writes and ship it. SCORM-tracked, completely free.
A course holds modules. A module holds sections. Every section is one of four formats, every course adds an AI Coding Exercise — and each step is tracked, scored and resumable, so you always return to the exact spot you left.
A cover image, a clear goal, free for everyone — and a certificate waiting at the finish line.
Usually four to eight per course, unlocking one after another as you make progress.
The smallest unit of learning — four formats, mixed and matched to fit each lesson.
Reference docs, cheat-sheets and API guides — yours to download and keep.
Screen-recorded walkthroughs that remember your place between sessions.
Auto-graded checkpoints that gate the next module until you pass.
In-browser coding tasks, scored live against real test cases.
A ready-made prompt points ChatGPT or Claude at the module's real specification. You review the build like a colleague's pull request, run it, and compare it with our reference solution on GitHub.
See how it worksAlmost nobody starts integration code from a blank file any more — an assistant writes the first draft and the developer decides whether it's right. Every LearnWisej course ends its material with an AI Coding Exercise that teaches exactly that skill, on real Wisej.NET code.
Copy the prompt. It points ChatGPT or Claude at the module's Markdown specification — the contract, the vocabulary and the Wisej.NET rules — so the model builds what the lesson taught, not a WinForms guess.
Everything an assistant writes for Wisej.NET compiles. Only some of it survives a real page load. Run the solution and check it against the module's list of mistakes assistants make most often.
Compare your build with our reference solution on GitHub, then add the next feature yourself — the way the rest of your career now looks.
No credits, no subscriptions, no checkout. Create a learner profile, open any course in the catalog and keep going for as long as you like — updates included.
Your name and an email address — we send a one-time code to confirm it's you. That's all it takes to keep your progress and certificates in sync.
Every course, lab, quiz, reading and AI coding exercise in the catalog is open to everyone. Pick where you want to start and jump in.
Finish a course to earn a verifiable certificate you can share with your team — and a badge for your GitHub profile.
Lessons, labs and quizzes in every course — and an AI Coding Exercise that puts them to work with ChatGPT or Claude.
Related courses stacked into a guided path. Follow them in order and go from beginner to production-ready — all free.
Every lab runs against an actual Wisej.NET project. You write the same code you'll ship — and it's graded against real tests.
Brief ChatGPT or Claude with a ready-made prompt, verify the Wisej.NET solution it returns, and extend it. The skill the job now demands, taught on real code.
How it worksShareable, verifiable proof of completion for your profile.
Stuck on a concept? Ask the built-in tutor — it answers from the exact lesson you're on, with real Wisej.NET C# examples.
Courses are authored by the engineers behind Wisej.NET and partners who run it in production every day.
Progress, scores and time-on-task recorded per section, resumable anywhere.
