DEV·2yUnderstanding IQueryable<T> in C#
Understanding IQueryable<T> in C# is crucial for efficient data querying. This interface, integral to LINQ, supports deferred execution and expression trees, enabling optimized and flexible queries over data sources like SQL databases or in-memory collections. It allows for method chaining to build complex queries and can be extended using custom extension methods for functionality like filtering, sorting, and pagination.

Community Picks·2yResult Pattern
The Result Pattern provides a structured method for dealing with errors in C#. It promotes clearer code and allows for more precise control over error handling. Using the Result Pattern can improve performance compared to using exceptions, especially in situations where errors occur frequently.
Waseem .NET Newsletter·2yEP 62 : Dependency Injection Explained in .NET
Dependency injection is a programming technique in which an object receives other required objects instead of creating them internally. Benefits of dependency injection include automatic handling of object creation and disposal, easy unit testing, and adaptability to changes without affecting existing code. Dependency injection can be implemented using the singleton, transient, or scoped approach.
DEV·2yPush your skills
Learn how to become a better developer by continuously improving your skills. Use resources like Pluralsight and Microsoft Learn, read documentation, keep things simple, use version control with GitHub, and prioritize learning over speed. Microsoft Visual Studio is recommended for coding, along with tools like Red Gate SQL Prompt and EF Power Tools. Dive into code basics with Microsoft Entity Framework Core or Dapper. Refactor code and incorporate best practices like using meaningful variable names and writing readable code. Continually learning is essential for growth as a developer.
Code Maze·2yProxy Design Pattern in C#
The proxy design pattern adds an extra layer of control over access to an object through a wrapper object (proxy) that acts on behalf of the original object (real subject). This pattern allows additional logic without modifying the original object's functionality. Use cases include caching, logging, protection, remote services, and conditional service resolution. While the pattern offers multiple benefits, it introduces complexity and potential maintenance overhead, particularly with asynchronous or multithreaded operations.
Code Maze·2yThe Semaphore Class in C#
The post introduces the Semaphore class in C# and compares it with the SemaphoreSlim class. It explains semaphore initialization, usage, and best practices for synchronization in multithreading. Named semaphores, which synchronize threads across processes, are also discussed. Examples with code demonstrate semaphore operations, and guidelines for avoiding common pitfalls like deadlocks are provided.
Code Maze·2yWhat Does the null! Statement Do?
The null! statement in C# is used to suppress the CS8618 warning, which indicates that a non-nullable reference type property might be null. By attaching the null-forgiving operator (!) to null, it marks a nullable type as non-nullable, bypassing compiler warnings. While useful for certain scenarios, developers should use it sparingly as it doesn't prevent runtime NullReferenceExceptions.
Ayende @ Rahien·2yRecording: Building a Database Engine in C# & .NET
Oren Eini, CEO of RavenDB, explores the process of building a database engine with C# and .NET, highlighting the language's capabilities for high-end system development. This session covers direct memory access, fine-grained control, and the blend of high-level concepts with low-level programming offered by C#.
