Pattern matching, introduced in C# 7, has become the preferred approach for checking data structure. It offers improved readability and expressiveness, concise syntax, flexibility and extensibility, switch expressions, deconstruction and tuple patterns, and enhanced error handling, making code more intuitive and easier to understand.
Switch expressions are a modern and recommended approach for implementing switch statements in .NET Core 3 and later. They offer advantages such as conciseness, expression evaluation, pattern matching, direct return value, exhaustiveness checking, scope isolation, and improved code refactoring and maintainability.
The recommended practice in .NET is to place using directives outside of the namespace in code files. This improves code cleanliness, readability, and helps avoid confusion, while also potentially optimizing performance and facilitating maintenance and refactoring tasks. Placing using directives outside the namespace enables efficient refactoring capabilities provided by tools like Visual Studio and CodeRush.
Removing unused parameters in code is important for several reasons. Firstly, it improves code readability and makes it easier for others to understand. Secondly, it helps with code maintenance, enhances performance, avoids bugs, and promotes better API design. Tools like CodeRush can be useful in automatically removing unused parameters and refactoring the code accordingly, streamlining the process.
For optimal performance, it is crucial to eliminate unnecessary value assignments.
In this blog post, the author discusses the importance of removing unnecessary expression values in coding. They highlight the benefits of improved code readability, performance optimization, bug prevention, and code maintainability. The author also provides an example where using discards, like the underscore character, can be used to explicitly indicate the intention of disregarding the result of an expression, thus making the code more clear and communicative.
C# 8 introduced the index-from-end operator for accessing items in a collection. This article shows you how to use the index operator.
Compound assignments in .NET have been available since its release and are the preferred way to modify numbers and strings, offering benefits such as conciseness, improved performance, and enhanced readability. By combining the operation and assignment into a single statement, compound assignment operators make the code more compact, efficient, and easier to comprehend, conveying the intention of the code clearly.

The readonly modifier is crucial in programming for creating immutable fields, ensuring integrity and preventing unintended modifications. Its absence can introduce errors, as highlighted by 270 missing instances in a code review. Utilizing readonly enhances performance, code clarity, and thread safety, ultimately contributing to more maintainable and robust code.
When code is modified or removed within a class, it is common for unused private members, such as variables, methods, and properties, to remain. Removing these unused private members is essential for enhancing code readability and facilitating maintenance.
