Learn ASP.NET Core
Learn ASP.NET Core through prerequisites, core workflows, projects, troubleshooting, and production practices.
Best for
- C# web APIs and backend applications
- Enterprise .NET services
- Applications using built-in dependency injection, middleware, configuration, and hosting
Prerequisites
- C# classes, interfaces, LINQ, exceptions, and async/await
- .NET CLI and project basics
- HTTP and relational database fundamentals
Learning sequence
Recommended Learning Order

Study Timeline
6 hours/week
Add persistence, validation, auth, and tests.
10 hours/week
Build and deploy a production-style API.
Project Progression
Beginner: validated API
Intermediate: relational CRUD service with auth
Portfolio: tested API with policies, health checks, logging, and deployment configuration
Common Mistakes
- Blocking async request code
- Using authentication without authorization policies
- Mixing persistence and transport models without clear contracts
- Ignoring middleware order
Job-Ready Skills
- ASP.NET Core request pipeline
- Dependency injection
- Validation
- Data access
- Auth and policies
- Testing and deployment
