What You'll Master

01. Environment Setup

• Visual Studio/VS Code installation
• .NET SDK
• Project structure

02. ASP.NET Core Introduction

• Middleware pipeline
• Configuration
• Dependency injection
• RESTful endpoints

03. Minimal APIs

• Minimal API syntax for rapid development
• CRUD operations without controllers
• Organize endpoints with route groups
• Built-in request validation

04. Dependency Injection

• Automatic dependency resolution (constructor injection)
• Control object lifecycle (scoped/singleton/transient)
• Type-safe configuration (Options pattern)

05. Entity Framework Core

• Model complex relationships in C#
• Query databases with LINQ
• Evolve schema safely (migrations)
• Handle one-to-many/many-to-many associations

06. Clean Architecture

• 4-layer architecture (Domain/Application/Infrastructure/API)
• Dependency inversion

07. Repository Pattern

• Decouple business logic from data access
• Implement with Entity Framework Core
• Enable easy unit testing via DI

08. Validation

• Declarative validation (DataAnnotations)
• Build custom validation logic
• Return consistent error responses

09. Blazor Basics

• Reusable UI components
• One-way and Two-way data binding
• Handle user interactions
• Initialize component state (lifecycle hooks)
• Show/hide UI conditionally

10. Blazor State Management

• Centralized state management (state container)
• Notify components of changes (events)
• Pass data down component trees (cascading)

11. Blazor Forms & Validation

• Two-way data binding (EditForm)
• Automatic validation (DataAnnotationsValidator)
• Display all errors (ValidationSummary)
• Show field-specific errors (ValidationMessage)

12. Blazor API Integration

• Make HTTP requests (HttpClient)
• Handle network failures gracefully
• Show loading indicators

13. Blazor Authentication & Security

• Track authentication state (AuthenticationStateProvider)
• Parse and validate JWT tokens
• Persist tokens securely
• Implement login/logout flows

14. Authentication

• Industry-standard authentication (JWT)
• Manage users securely (ASP.NET Core Identity)
• Handle user registration
• Authenticate users and issue tokens
• Secure endpoints with token validation

15. Authorization

• Restrict features by role
• Embed permissions in JWT tokens
• Create flexible access rules (policies)

16. Error Handling

• Catch errors globally (middleware)
• Create domain-specific exceptions
• Return standard error responses (ProblemDetails)

17. Logging

• Rich, queryable logs
• Write logs to multiple destinations
• Control log verbosity (log levels)
• Manage log file size (rolling logs)

18. Testing

• Unit test with mocking
• Test entire API flows (integration tests)
• Test without external dependencies (in-memory DB)
• Write readable tests (Arrange-Act-Assert)

19. SignalR

• Set up real-time endpoints (SignalR hubs)
• Push updates to all clients
• Manage client connections
• Handle connect/disconnect events

20. Performance Optimization

• Eliminate redundant database queries
• Speed up read-only queries
• Reduce server load (response caching)
• Keep app responsive (async/await patterns)

21. API Versioning

• Version APIs in URLs
• Support multiple versions simultaneously
• Communicate deprecation to clients

Appendix 1. Minimal API Code Organization

• Organize by feature (vertical slices)
• Automatic endpoint registration
• Modular, maintainable structure

Appendix 2. Minimal API Cross-Cutting Concerns

• Reusable request/response processing (filters)
• Automatic validation across endpoints
• Run tasks independently (background services)
• Test complete application flows
