IEnumerable is used for in-memory data collections and supports deferred execution, while IQueryable is designed for remote data querying and can be translated into query languages like SQL. Using IEnumerable is best for local data collections, whereas IQueryable is ideal for querying large external data sources efficiently. 48 1 2. 2 [](https://daily.dev/posts/discard-variable-in-c-net-26eqpmshd "Discard Variable in C# .NET") Article C# Corner · 2y Discard Variable in C# .NET The discard variable, introduced in C# 7.0 and represented by an underscore (\_), is a special, read-only variable used to ignore values intentionally. This feature can lead to more readable and maintainable code by avoiding unnecessary variables. Common usage scenarios include deconstructing tuples, pattern matching, handling out parameters, and optimizing LINQ queries. The discard variable enhances code clarity and can aid in performance optimization by reducing memory usage. 45 3. 3 [](https://daily.dev/posts/liskov-substitution-principle-in-c-with-example-d2a7hjf9b "Liskov Substitution Principle in C# with Example") Article C# Corner · 2y Liskov Substitution Principle in C# with Example The Liskov Substitution Principle (LSP) is one of the SOLID principles of object-oriented design, which ensures that objects of a superclass can be replaced by objects of a subclass without introducing errors. The post provided an example with a Bird class and an Ostrich class that violates LSP, and demonstrated refactoring the code by introducing an IBird interface and specific bird classes to adhere to LSP, making the code robust, maintainable, and scalable. 38 2 4. 4 [](https://daily.dev/posts/c-abstract-class-with-examples-rvwn370of "C# Abstract Class with Examples") Article C# Corner · 2y C# Abstract Class with Examples Abstract classes in C# provide a blueprint for other classes, allowing for shared functionality, default behavior, and partial implementation. They contain abstract methods, which must be implemented by derived classes, as well as non-abstract methods that can be inherited. Abstract classes are essential for code reusability, extensibility, and maintainability, differentiating from interfaces which solely define method signatures. Understanding their usage is crucial for building scalable and maintainable applications in C#. 34 5. 5 [](https://daily.dev/posts/understanding-json-web-tokens-jwt--kitsqeuat "Understanding JSON Web Tokens (JWT)") Article C# Corner · 2y Understanding JSON Web Tokens (JWT) JSON Web Tokens (JWT) provide a secure, efficient means of authenticating and authorizing users in web applications. They consist of three parts: Header, Payload, and Signature, which are encoded and signed for security. JWTs' self-contained nature makes them ideal for scalable, stateless communication. Implementation involves generating, storing, and validating tokens while adhering to best practices such as securing secret keys, using HTTPS, and setting token expiration times. 32 6. 6 [](https://daily.dev/posts/strategy-pattern-in-net-8-0-minimal-api-with-dependency-injection-oct40hg4z "Strategy Pattern in .NET 8.0 Minimal API with Dependency Injection") Article C# Corner · 2y Strategy Pattern in .NET 8.0 Minimal API with Dependency Injection Explore how to implement the Strategy pattern in .NET 8.0 using Minimal API and dependency injection. Learn to create a flexible and maintainable payment processing system by encapsulating multiple payment method algorithms, defining a strategy interface, implementing concrete strategies, setting up payment context, configuring the Minimal API with dependency injection, and testing the endpoint. 32 7. 7 [](https://daily.dev/posts/interface-vs-abstract-class-3atqtcgcb "Interface Vs Abstract Class") Article C# Corner · 2y Interface Vs Abstract Class Understanding abstract classes and interfaces in C# is crucial for robust and scalable application design. Abstract classes provide a common base with shared code, supporting concrete methods, fields, and constructors. Interfaces define method contracts without implementation, allowing for multiple inheritance and promoting loose coupling. The choice between them depends on your specific requirements and design considerations. 24 1 8. 8 [](https://daily.dev/posts/multithreading-and-multiprocessing-in-python-wforxssux "Multithreading and Multiprocessing in Python") Article C# Corner · 2y Multithreading and Multiprocessing in Python Multithreading and multiprocessing are essential techniques for optimizing performance in Python applications. Multithreading, ideal for I/O-bound tasks, allows multiple threads to run concurrently within a single process. Multiprocessing, better suited for CPU-bound tasks, utilizes multiple CPU cores by spawning separate processes. Choosing the right approach depends on the task at hand and can drastically enhance application efficiency. 22 9. 9 [](https://daily.dev/posts/encapsulation-inheritance-and-polymorphism-in-c--retkn79w1 "Encapsulation, Inheritance, and Polymorphism in C#") Article C# Corner · 2y Encapsulation, Inheritance, and Polymorphism in C# Object-oriented programming in C# involves key principles like encapsulation, inheritance, and polymorphism. Encapsulation bundles data and methods into classes and controls access using access modifiers. Inheritance allows code reuse and relationship hierarchies by enabling a class to inherit properties and methods from another class. Polymorphism provides dynamic behavior through method overriding and interfaces, letting methods act differently based on object types. These principles enhance code modularity, reusability, and flexibility, resulting in robust, maintainable applications. 22 10. 10 [](https://daily.dev/posts/implementing-the-saga-pattern-in-c--zeu6twj77 "Implementing the Saga Pattern in C#") Article C# Corner · 2y Implementing the Saga Pattern in C# The Saga pattern helps manage distributed transactions and ensures data consistency across microservices by breaking down a long-running transaction into smaller, manageable ones. It uses a central coordinator (orchestrator) or a choreography approach to handle these transactions. This guide demonstrates an implementation in ASP.NET Core with an example involving order processing, inventory management, and payment services. 21 1 11. 11 [](https://daily.dev/posts/domain-driven-design-uimjnpcst "Domain-Driven Design") Article C# Corner · 2y Domain-Driven Design Domain-Driven Design (DDD) provides a structured approach to .NET development, focusing on creating robust and domain-centric applications. Key concepts include defining domain models with aggregates, entities, and value objects, utilizing infrastructure tools like EF Core, Swagger, and Kafka, and handling business logic with MediatR and AutoMapper. Further, it covers crafting APIs with the Presenter pattern in ASP.NET Core, maintaining code quality through testing and best practices, and scaling applications effectively. Continuous learning and community engagement are also emphasized for staying updated in the DDD landscape. 20 [See all C# Corner archives](/sources/csharpcorner/best-of) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@graph":[{"@type":"CollectionPage","@id":"https://daily.dev/sources/csharpcorner/best-of/2024/07#page","url":"https://daily.dev/sources/csharpcorner/best-of/2024/07","name":"Best C# Corner Posts — July 2024","description":"The most upvoted C# Corner posts from July 2024, curated by the daily.dev community.","isPartOf":{"@type":"WebSite","url":"https://daily.dev"}},{"@type":"ItemList","@id":"https://daily.dev/sources/csharpcorner/best-of/2024/07#items","numberOfItems":11,"itemListElement":[{"@type":"ListItem","position":1,"url":"https://daily.dev/posts/differences-between-ienumerable-and-iqueryable-in-c--of0cehmdd","name":"Differences Between IEnumerable and IQueryable in C#"},{"@type":"ListItem","position":2,"url":"https://daily.dev/posts/discard-variable-in-c-net-26eqpmshd","name":"Discard Variable in C# .NET"},{"@type":"ListItem","position":3,"url":"https://daily.dev/posts/liskov-substitution-principle-in-c-with-example-d2a7hjf9b","name":"Liskov Substitution Principle in C# with Example"},{"@type":"ListItem","position":4,"url":"https://daily.dev/posts/c-abstract-class-with-examples-rvwn370of","name":"C# Abstract Class with Examples"},{"@type":"ListItem","position":5,"url":"https://daily.dev/posts/understanding-json-web-tokens-jwt--kitsqeuat","name":"Understanding JSON Web Tokens (JWT)"},{"@type":"ListItem","position":6,"url":"https://daily.dev/posts/strategy-pattern-in-net-8-0-minimal-api-with-dependency-injection-oct40hg4z","name":"Strategy Pattern in .NET 8.0 Minimal API with Dependency Injection"},{"@type":"ListItem","position":7,"url":"https://daily.dev/posts/interface-vs-abstract-class-3atqtcgcb","name":"Interface Vs Abstract Class"},{"@type":"ListItem","position":8,"url":"https://daily.dev/posts/multithreading-and-multiprocessing-in-python-wforxssux","name":"Multithreading and Multiprocessing in Python"},{"@type":"ListItem","position":9,"url":"https://daily.dev/posts/encapsulation-inheritance-and-polymorphism-in-c--retkn79w1","name":"Encapsulation, Inheritance, and Polymorphism in C#"},{"@type":"ListItem","position":10,"url":"https://daily.dev/posts/implementing-the-saga-pattern-in-c--zeu6twj77","name":"Implementing the Saga Pattern in C#"},{"@type":"ListItem","position":11,"url":"https://daily.dev/posts/domain-driven-design-uimjnpcst","name":"Domain-Driven Design"}]},{"@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Sources","item":"https://daily.dev/sources"},{"@type":"ListItem","position":3,"name":"C# Corner","item":"https://daily.dev/sources/csharpcorner"},{"@type":"ListItem","position":4,"name":"Best of","item":"https://daily.dev/sources/csharpcorner/best-of"},{"@type":"ListItem","position":5,"name":"July 2024"}]}]} ```
