Design patterns are proven solutions to common software design problems. They help you write: Clean code Maintainable systems Scalable applications In modern development with .NET 9, design patterns are widely used in: ASP.NET Core APIs Microservices Blazor applications Enterprise systems What Are Design Patterns? Design patterns are templates or best practices, not ready-made code. They…
A key component of application security is authentication, which guarantees that only legitimate users may access resources that are protected. A versatile and adaptable framework that supports many schemes—from conventional cookie-based authentication to contemporary token-based methods like JWT and OAuth2—is used to implement authentication in.NET Core. Core Authentication Approaches in .NET Core 1. Cookie-Based Authentication…
Reducing duplicate server processing is essential for developing high-performance web applications. By storing the generated HTML answer and reusing it for further requests, output caching in ASP.NET Core greatly speeds up response times and lowers server load. Using CacheTagHelper is one of the most practical ways to achieve this at the view level. It makes…
When using ASP.NET Core or any other secure application development framework.One of the most important tasks in a NET-based system is correctly managing user passwords. If your database is compromised, storing plain-text passwords is a significant security risk and may result in data leaks. Password hashing algorithms are used by developers to safeguard user credentials….
One of the most crucial ideas you will come across when working with ASP.NET Core is the Middleware Pipeline. It is essential to a web application’s handling of requests and responses. Middleware is the solution if you’ve ever wondered how a request moves from the browser to your application and back to the user. To…
When building modern web applications, security is not optional—it is a necessity. One of the most important parts of securing your application is controlling who can access what. Not every user should be able to perform every action. For example, in a real-world system: An Admin can manage users and data A normal User can…
Dependency Injection (DI), an integrated feature of ASP.NET Core, aids in controlling the creation and lifespan of objects. AddTransient, AddScoped, and AddSingleton are three often used methods when registering services in the DI container. Building scalable, high-performance, and error-free applications requires an understanding of the differences between AddTransient, AddScoped, and AddSingleton. Memory problems, unexpected behavior,…
Interviews using ASP.NET Core frequently center on how apps function in actual production settings. Interviewers want to know how you manage slow APIs, big data sets, async problems, and external dependencies, not just syntax. In order to help you react confidently, this article explains frequently requested ASP.NET Core interview questions based on real-world performance settings…
ASP.NET middleware To manage each HTTP request and response, core software components are put together into an application pipeline. Each link in the chain determines whether to short-circuit the pipeline by producing a response directly or process the request and forward it to the subsequent middleware. Every piece of middleware Chooses whether to pass the…
In contemporary application development, API versioning is an essential technique that enables teams to modify APIs without affecting current clients. Frontend frameworks, microservices, third-party systems, and mobile apps frequently use APIs in enterprise ASP.NET Core projects. A breaking update that is implemented without versioning may result in client failures, production disruptions, and lost revenue. Definitions,…
