Basic C# knowledge is helpful, but not required. The course starts from fundamentals and progressively builds to advanced topics. Complete beginners can follow along.

The course is built with .NET 10 and covers the latest features and best practices. Code samples are updated to use modern C# syntax and patterns.

The course contains 60+ hours of content across 125+ lessons. Most students complete it in 4-8 weeks studying 2-3 hours daily, but you can go at your own pace.

Currently, we don't offer certificates. However, the practical skills and portfolio projects you'll build are far more valuable to employers than certificates.

Yes! Complete source code for all lessons is available on GitHub. You can clone the repository and follow along with each lesson.

ASP.NET Core Web API is Microsoft's framework for building RESTful HTTP services in C# and .NET. It powers backends at companies like Stack Overflow, Microsoft, and thousands of enterprises. Learning it opens doors to backend developer, full-stack developer, and cloud engineer roles with salaries ranging from $95K to $150K+.

.NET 10 is one of the fastest backend frameworks available - consistently outperforming Node.js and Spring Boot in TechEmpower benchmarks (https://www.techempower.com/benchmarks). It offers native AOT (Ahead-of-Time) compilation, minimal APIs, built-in OpenAPI support, and seamless Docker/cloud deployment. This course covers all of these modern .NET 10 features.

This course offers 125+ lessons and 60+ hours of content - more than most paid courses on Udemy. It covers advanced topics like Clean Architecture, Docker deployment, observability, and testing that many paid courses skip. The biggest difference? It's 100% free with full source code on GitHub, and it's kept up to date with the latest .NET version.

Absolutely. The course covers the exact topics asked in .NET backend interviews - REST API design, Entity Framework Core (EF Core), JWT (JSON Web Token) authentication, caching with Redis, CQRS (Command Query Responsibility Segregation), SOLID design patterns, Clean Architecture, and Docker containerization. Many students have used this course to land their first .NET developer job or transition from other tech stacks.

ASP.NET Core consistently outperforms Node.js in raw throughput and latency benchmarks (TechEmpower, 2025). It offers built-in dependency injection, strong typing with C#, native async/await that doesn't block the event loop, and enterprise-grade security features out of the box. Node.js has a larger npm ecosystem and is great for lightweight services, but for production APIs that need performance, type safety, and long-term maintainability - ASP.NET Core with .NET 10 is the stronger choice. This course teaches you to leverage all of these advantages.

.NET is one of the top 3 backend frameworks globally, powering services at Microsoft, Stack Overflow, UPS, GE, and thousands of enterprises. With .NET 10, you get native AOT (Ahead-of-Time) compilation for faster startup, built-in OpenAPI support, minimal APIs for lightweight endpoints, and first-class cloud-native tooling for Docker, Kubernetes, and serverless. The job market reflects this - .NET backend developers earn $95K–$150K+ annually, and demand continues to grow as companies modernize legacy systems to ASP.NET Core.

With structured learning, you can build your first production-ready REST API in 4-6 weeks. This course is designed for exactly that pace - start with REST fundamentals and your first endpoint in Week 1, move to database operations with Entity Framework Core in Week 2, add authentication and advanced patterns in Weeks 3-4, and finish with Docker deployment, testing, and observability in Weeks 5-6. Most students who follow the curriculum consistently report being job-ready within 2 months.

ASP.NET Core Web API skills qualify you for backend developer, full-stack developer, cloud engineer, and solutions architect roles. The average salary for a .NET backend developer in the US is $120K (Glassdoor, 2025), with senior roles reaching $150K-$180K+. Companies actively hiring .NET developers include Microsoft, Accenture, Deloitte, JPMorgan, and thousands of startups. This course covers the exact stack most employers look for: REST APIs, Entity Framework Core, authentication, Clean Architecture, Docker, and CI/CD.

This course covers 12 modules: (1) REST API fundamentals, middleware, dependency injection, and logging with Serilog; (2) Entity Framework Core 10 - CRUD, relationships, migrations, soft deletes, bulk operations, and compiled queries; (3) Advanced patterns - CQRS with MediatR, FluentValidation, Options Pattern, Result Pattern, API versioning, and SignalR; (4) Performance - benchmarking, profiling, response compression, in-memory caching, Redis distributed caching, and output caching; (5) HTTP clients with Polly resilience and Refit; (6) Background jobs with Hangfire and Quartz.NET; (7) Security - JWT authentication, refresh tokens, role-based and policy-based authorization, CORS, and OAuth 2.0; (8) Clean Architecture with DDD, CQRS, and Vertical Slice Architecture; (9) File handling - uploads, downloads, S3 integration, and image processing; (10) Observability - OpenTelemetry, Prometheus, Grafana, health checks, and ELK stack; (11) Testing - unit testing, integration testing with TestContainers, and API testing; (12) Deployment - Docker containerization, CI/CD with GitHub Actions, and YARP API Gateway.

The most effective way to learn ASP.NET Core Web API in 2026 is through a structured, project-based course that covers the full stack - not just CRUD. Start with REST fundamentals and HTTP concepts, then progress to Entity Framework Core for database access, add authentication and authorization, learn architectural patterns like Clean Architecture and CQRS, and finally cover Docker deployment and CI/CD. This free course follows exactly that progression across 125+ lessons, with complete source code on GitHub so you can build real projects alongside each lesson.
