Introduction to ASP.NET Core
Learn the fundamentals of ASP.NET Core, modern backend development, dependency injection, routing, controllers, REST APIs and deployment.

By the end you'll be able to
- Build secure web applications
- Develop RESTful APIs
- Configure authentication systems
- Apply clean backend architecture
- Prepare for .NET backend roles
Is this course for you?
This is right for you if you…
- You finished the C# foundation course (#1) and the natural next question is 'how do I build something on the web with this'
- You're targeting Junior .NET backend roles — this is THE standard junior .NET interview project
- You want to write APIs that other developers will hit — and you want to do it the way the team will at your first job
Don't take this course if you…
- You don't know C# yet — start with #1. ASP.NET Core builds on top of C#; without the language layer this course is hieroglyphs
- You think 'web development = frontend' — this course is the OPPOSITE side. If frontend is your goal, take #6 + #11
- You want to learn Node.js — different stack entirely. Course #19 covers Node + REST APIs

Oleksii Anzhiiak is a Software Architect, Senior .NET Engineer, and Co-Founder of ToyCRM.com and ProfectusLab. With over 15 years of experience, he specializes in distributed systems, cloud infrastructure, high-load backend development, and identity platforms. Oleksii designs complex architectures, builds secure authentication systems, and develops modern engineering education programs that help students achieve real career results.
Currently leads architecture for ToyCRM.com — a multi-tenant CRM platform built on .NET by our team. The same patterns and design decisions used there appear directly in the courses: identity & auth, distributed services, code review culture. You learn from engineers actively shipping production code, not from a textbook.
Syllabus
This course covers the fundamentals of ASP.NET Core:
- 1 Module 1: Introduction to ASP.NET Core & .NET
- 2 Module 2: Project Structure & Program.cs
- 3 Module 3: Dependency Injection Fundamentals
- 4 Module 4: Routing & Endpoints
- 5 Module 5: Controllers & Minimal APIs
- 6 Module 6: Working with Models & DTOs
- 7 Module 7: Entity Framework Core Basics
- 8 Module 8: REST API Design & Best Practices
- 9 Module 9: Authentication & Authorization
- 10 Module 10: Middleware & Request Pipeline
- 11 Module 11: Logging & Configuration
- 12 Module 12: Deployment to the Cloud (Azure / AWS / Docker)
Prerequisites
Basic computer skills and willingness to learn. Course materials will guide you step by step.
Basic C# knowledge required.
What you'll build
You leave with a real REST API you built and deployed — auth that works, endpoints that handle errors properly, a clean controller/service/repository structure. The thing every junior .NET interview asks 'show me a project you built' about. You'll have one.
- ASP.NET Core MVC architecture
- RESTful Web API development
- Middleware pipeline configuration
- Dependency injection and services
- Authentication and authorization
- Entity Framework Core integration
- Configuration and environment management

How to Pass a System Design Interview: A Senior Engineer's Playbook
Most system design advice is theoretical noise. This is the repeatable framework I use to evaluate candidates — and that you can use to pass any system design interview at a mid or senior level.
First lesson on us. Decide after meeting your instructor.
Sit in on the first session. If after lesson 1 you decide the instructor isn't the right fit, you don't pay for it — and no awkward conversation. (Trial offer applies to courses with more than 5 lessons; this one qualifies.)
Pricing & what's included
What's included
- 12 live sessions × 2 hours each — taught by the instructor, not a recording playback
- Slide deck for every session — yours to keep and refer back to
- Working code files and any data files used in class — cloned to your machine
- Weekly homework with personal code review from the instructor
- Recording on request — give the teacher a heads-up ("can't make Tuesday, please record it") and the session is recorded for you
Frequently asked questions
How much time per week will this take?
Plan for the live sessions plus roughly 1.5–2 hours of practice per session. Most students who finish on schedule put in 4–6 hours a week total. If you put in less, you still finish — it just takes longer.
What if I miss a class?
Tell the teacher BEFORE the session — "I can't make Tuesday, please record it" — and the teacher records that lesson and sends it to you. Recordings aren't a default catch-up archive; they're produced on request when you give a heads-up. After the lesson you do the homework, bring questions to the next session.
What's included in the price?
Live sessions with the teacher; the slide deck for each session (yours to keep); the working code files and any data files used in class; weekly homework with code review; and recordings of the sessions you give advance notice for. Anything beyond that — a certificate, alumni access, mock interviews — is listed explicitly in "What's included" above the FAQ for the courses where it applies.
What if I sign up and the teacher isn't a fit?
For courses with more than 5 lessons, the first session is effectively a trial — if after lesson 1 you decide the teacher isn't a fit, you don't pay for it. We'd rather you walk away after one lesson than push through 9 weeks of bad chemistry. (Courses with 5 or fewer lessons are short enough that the standard pricing applies — the trial offer doesn't make sense at that length.)
Can I get a refund partway through?
Yes, while more than half the course is still unused — i.e. you've attended fewer than 50% of the lessons. The refund covers the unused portion proportionally. Past the halfway point we don't refund, on the assumption that the value has been delivered.
Can I switch the language of instruction?
The live sessions run in the language listed under "Available Languages" above. Slides and code files are typically available in all four (English, Russian, Ukrainian, Georgian). Many students attend sessions in one language and read materials in another — that's normal.
Will I be ready for a real job after this course?
One course rarely gets anyone hired by itself — for any field. What this course gives you is the foundation a junior hiring manager expects: working code you wrote yourself, the vocabulary to read other people's code, and the practice habits that make you employable. The honest answer to "am I ready?" is on our roadmap (link in the page header) — open the level you want to reach and read the "You're ready when" checklist.
Can I pay in instalments?
Yes for courses with a "Monthly Payment" option in the at-a-glance ribbon — usually two or three equal monthly payments. Courses without that option are paid in one go. If the price is the blocker, write to us — we look at every case.
