TOP 10 .NET CODE REFACTORING TECHNIQUES!
Common code smells in .NET applications that indicate the need for refactoring include long methods, large classes, duplicate code, primitive obsession, god objects, and excessive or outdated comments.
To refactor large methods and classes, identify responsibilities, extract methods, encapsulate logic, use design patterns, and write unit tests.
For refactoring legacy .NET code without breaking functionality, create a test suite, automate tests, make small incremental changes, use refactoring patterns like extract method and extract class, and leverage SOLID principles, DRY, and KISS. Utilize modern .NET features and version control, and automate with CI/CD. Keep documentation updated and communicate with the team.
The primary goals of refactoring are to improve readability, maintainability, and performance optimization.
When handling dependencies, understand and plan by mapping dependencies, decouple and inject, refactor incrementally, test, and collaborate while documenting changes.
To ensure refactored code remains performant, use unit tests, profiling tools like dotTrace, async/await, optimize LINQ queries, employ caching mechanisms, minimize memory allocations, and implement strategy patterns.
Manage database schema changes by maintaining version control, using automated migration scripts, documenting SQL scripts, integrating changes into CI/CD, and establishing rollback strategies.
To refactor and modernize .NET applications with outdated frameworks or libraries, update gradually, manage dependencies, migrate to the latest .NET, refactor legacy code, implement automated testing, use continuous integration, and monitor and optimize performance.
For improving readability of complex conditional logic, use method extraction, replace conditionals with polymorphism, use the strategy pattern, and simplify boolean logic.
Ensure refactored code is properly documented and maintainable with code comments, up-to-date documentation, regular code reviews, automated documentation tools, and continuous learning among the development team.
