Learn how to implement an API Gateway in .NET using Ocelot, a powerful open-source library. This guide covers the essentials of routing, load balancing, security, and microservices management in .NET Core.

xploring ValueTask in C#" delves into the intricacies of the ValueTask type introduced in C#. It compares ValueTask with Task, highlighting performance benefits and appropriate use cases.

ASP.NET Core Identity is a membership system for managing authentication and authorization in web applications. It includes components like IdentityUser, IdentityRole, and Claims, and features such as password hashing, email confirmation, and two-factor authentication.

Avoid using `await` inside C# loops as it causes sequential execution and resource contention, leading to poor performance. Instead, use alternatives like `Task.WhenAll`, `Parallel.ForEachAsync`, or `SemaphoreSlim` to handle asynchronous operations concurrently and efficiently.

CQRS (Command Query Responsibility Segregation) in .NET Core separates read and write operations for better scalability and performance. By using distinct models for commands and queries, it simplifies complex data handling, improves security, and enhances maintainability.

Intermediate code optimization in C# improves performance by refining Intermediate Language (IL) code. Techniques like inlining, loop optimizations, dead code elimination, and constant folding enhance runtime efficiency and reduce overhead.

In this article, we will Understand key concepts, such as iterator methods and custom iteration patterns, and enhance your C# programming skills with practical examples and tips.

Discover how GROUP BY aggregates data into summary rows, while PARTITION BY divides data into partitions for window functions. Master these techniques to enhance your SQL querying skills.

Exception handling in ASP.NET Core is crucial for application stability. Exception filters provide a centralized way to manage errors, log them, and return custom responses, enhancing maintainability and user experience.

Registering multiple services with a single interface in .NET Core enhances flexibility and testability, allowing different implementations for various concerns, runtime configuration, and easy unit testing.

Sealed classes in C# are a vital concept in object-oriented programming, preventing other classes from inheriting them. This ensures a secure and stable class hierarchy by stopping further extension.
