Asynchronous Programming

Unlock the full potential of .NET by mastering asynchronous programming. Learn how to write non-blocking code using async and await keywords to improve application responsiveness and scalability, especially in I/O-bound operations.

Key Concepts:

  • The Task and Task<TResult> types
  • Cancellation tokens for managing long-running operations
  • Handling exceptions in asynchronous code
  • Best practices for asynchronous method design

Dive deeper into asynchronous patterns and explore scenarios like parallel processing and event-driven architectures.

Dependency Injection

Understand Dependency Injection (DI) as a powerful design pattern that promotes loose coupling and enhances the testability of your .NET applications. Learn how to implement DI using built-in .NET Core mechanisms or popular third-party libraries.

Core Components:

  • Service lifetimes (Transient, Scoped, Singleton)
  • Registration of services
  • Consuming injected dependencies
  • Built-in DI container in ASP.NET Core

Discover how DI can simplify complex object graphs and make your code more maintainable.

Performance Optimization

Elevate your application's performance with advanced optimization techniques. This section covers profiling, memory management, efficient algorithm design, and leveraging .NET's built-in performance features.

Techniques:

  • Using the built-in profiler
  • Memory allocation and garbage collection tuning
  • Span<T> and Memory<T> for efficient memory access
  • LINQ performance considerations
  • Profiling with the BenchmarkDotNet library

Learn to identify bottlenecks and implement targeted optimizations for maximum impact.

Security Best Practices

Secure your .NET applications against common threats. This module explores essential security principles, authentication, authorization, data protection, and secure coding practices.

Topics Covered:

  • Input validation and sanitization
  • OWASP Top 10 in .NET context
  • Authentication and authorization mechanisms (e.g., JWT, OAuth)
  • Cryptography and data encryption
  • Secure API design

Implement robust security measures to protect your users and data.

Advanced Collections

Go beyond basic collections and explore specialized data structures in .NET that offer optimized performance for specific scenarios. Understand when and how to use them effectively.

Explore:

  • ConcurrentDictionary<TKey, TValue> for thread-safe operations
  • Immutable collections for functional programming patterns
  • ListDictionary vs. Dictionary performance characteristics
  • Custom collection implementations

Reflection and Metaprogramming

Leverage the power of reflection to inspect and manipulate types and members at runtime. This section also introduces metaprogramming techniques for generating code dynamically.

Learn About:

  • Using the System.Reflection namespace
  • Invoking methods and accessing properties dynamically
  • Attributes and their use cases
  • Source generators for compile-time code generation

Understand the trade-offs and best practices when working with reflection.
