Understanding the core of the .NET ecosystem:

• .NET Runtime and Common Language Runtime (CLR)
• NuGet Package Manager for managing libraries
• Assemblies and DLLs
• Garbage Collection

🔵 Version Control

🟢 Git

Version control is essential for collaboration:

• Basic Git commands (clone, commit, push, pull)
• Branching and Merging workflows
• Using platforms like GitHub or GitLab

🔵 Package Managers

🟢 NuGet

• Learn how to manage and integrate third-party libraries via NuGet.

🔵 Web Development with ASP.NET Core

🟢 ASP.NET Core Basics

• Middleware & Request Pipeline
• Routing & Endpoints
• Dependency Injection
• Controllers & Actions
• Model Binding & Validation

🟢 Razor Pages & MVC

• Views, Partial Views, and Layouts
• View Components
• Tag Helpers & View Models

🟢 Blazor (Optional)

• Blazor Server vs WebAssembly
• Building interactive UI components
• State management with Blazor

🔵 APIs and Microservices

🟢 RESTful APIs

• Creating APIs with Controllers and Routes
• HTTP Methods & Status Codes
• API Validation
• API Versioning
• API documentation with Swagger / OpenAPI

🟢 Authentication & Authorization

• Implementing JWT (JSON Web Tokens)
• OAuth2 & OpenID Connect flows
• IdentityServer integration

🟢 Real-time Communication

• SignalR for WebSockets and real-time apps
• gRPC for high-performance communication

🟢 Microservices Architecture

• API Gateway pattern
• Service Discovery tools
• Event-Driven Architecture using message brokers

🔵 Databases & ORM

🟢 Relational Databases

• SQL Server, PostgreSQL, MySQL

🟢 Entity Framework Core

• Code First & Database First approaches
• Migrations & Data Seeding
• Querying data with LINQ
• Transactions and Unit of Work pattern
• EF Core performance tuning

🔵 Testing

🟢 Unit Testing

• Frameworks like xUnit, MSTest, NUnit

🟢 Integration Testing

• End-to-end testing strategies

🟢 API Testing

• Tools like Postman & RestSharp

🟢 Mocking Dependencies

• Libraries like Moq & FakeItEasy

🔵 Performance Optimization

• Caching (MemoryCache, Redis)
• Async/Await & Multithreading concepts
• Connection Pooling
• Avoiding and detecting memory leaks

🔵 Cloud & Deployment

• Hosting on Azure, AWS, or Google Cloud
• CI/CD pipelines (GitHub Actions, Azure DevOps)
• Docker & Kubernetes for containerization
• Serverless architectures with Azure Functions

🔵 Security Best Practices

• Data Protection (Encryption, Hashing)
• Securing APIs (Rate Limiting, CORS, Authentication)
• Mitigating OWASP Top 10 vulnerabilities

🔵 Advanced Topics

• Clean Architecture for scalable solutions
• CQRS & MediatR pattern for separation of concerns
• Event-Driven Systems with RabbitMQ or Kafka
• GraphQL APIs with ASP.NET Core

🔵 Soft Skills

• Effective communication & writing documentation
• Code Reviews & Pair Programming
