C# (.NET): Tips and Best Practices

The book "C# (.NET): Tips and Best Practices" is a practical guide that will help you write clean, efficient, and maintainable code on the .NET platform. The author, Alexey Gromov, a senior developer with 10 years of experience, has compiled proven techniques, patterns, and recommendations that are actually used in commercial development into one book.

• Modern C# and .NET — an analysis of the latest language features (records, pattern matching, nullable reference types) and platform (.NET 8/9, AOT, Minimal API).
• Architecture and Patterns — SOLID, Dependency Injection, Repository, CQRS, Event Sourcing. How to avoid overcomplicating a project and choose the right solutions.
• Performance and Memory — Span, Memory, object pools, asynchronous programming (ValueTask, Channels), profiling, and benchmarking.
• Security — protection against injections, XSS, CSRF, working with secrets, OWASP Top 10 in the context of .NET.
• Testing and Code Quality — unit tests (xUnit, NUnit), mocks (Moq, NSubstitute), integration testing, code review, and static analysis.
• Working with Data — Entity Framework Core (query optimization, migrations), Dapper, NoSQL (MongoDB, Redis), caching.
• DevOps and CI/CD — Docker containerization, GitHub Actions, Azure DevOps, setting up pipelines for .NET projects.
• Real-World Cases — examples from practice: refactoring legacy code, migrating from .NET Framework, optimizing high-load services.

Who is this book for?

• Beginner C# developers who want to immediately learn the right approaches and avoid common mistakes.
• Middle and Senior developers looking to deepen their knowledge of performance, architecture, and security.
• Team Leads and architects who need a structured reference of best practices for their team.
• Developers from other languages (Java, Python) transitioning to .NET.

What you will learn after reading:

• How to write code that is easy to maintain and extend.
• Which tools and libraries actually speed up development.
• How to avoid pitfalls when working with asynchrony, memory, and multithreading.
• How to design APIs and microservices ready for high loads.
• How to implement a culture of testing and code review in your team.

The book contains over 200 practical examples, checklists, and ready-made code templates. All examples are available on GitHub and kept up to date.
