Browser security prevents a web page from making requests to a different domain than the one that served the web page. This restriction is called the same-origin policy. The same-origin policy prevents a malicious site from reading sensitive data from another site. Sometimes, you might want to allow other sites to make cross-origin requests to your application. This is when you have an API hosted independently to your web applications talking...

In this article, We will talk about Onion Architecture In ASP.NET Core and it’s advantages. We will also together build a WebApi that follows a variant of Onion Architecture so that we get to see why it is important to implement such an architecture in your upcoming projects. You can find the source code of this implementation on my GitHub. The Need to Follow an Architecture To maintain structural Sanity in Mid...

Caching is the process of storing the data that’s frequently used so that data can be served faster for any future requests. Suppose we have a very lightweight process which talks to another server whose data is not going to change frequently; “Our service” and “Users Service” (which returns an array of users) respectively. Without any caching in place, we would be making multiple requests which will ultimately result in timeouts...

The primary purpose of any caching mechanism is to improve performance of an application. As an ASP.NET developer you are probably aware that ASP.NET web forms as well as ASP.NET MVC could used Cache object to cache application data. This was often called server side data caching and was available as an inbuilt feature of the framework. Although ASP.NET Core doesn't have Cache object as such, you can implement in-memory...

RSS stands for "Really Simple Syndication". It is a web feed mechanism, which helps applications or clients get updated content from websites in a timely fashion and empower applications to get content from more than one website regularly without having to manually check for new content. The best example for this is a news aggregator application, which brings in news articles from more than one news websites and regularly checks for...

Microservices The term microservices portrays a software development style that has grown from contemporary trends to set up practices that are meant to increase the speed and efficiency of developing and managing software solutions at scale. Microservices is more about applying a certain number of principles and architectural patterns as architecture. Each microservice lives independently, but on the other hand, also all rely on each other. All microservices in a project...

Introduction The Onion Architecture term was coined by Jeffrey Palermo in 2008. This architecture provides a better way to build applications for better testability, maintainability, and dependability on the infrastructures like databases and services. This architecture's main aim is to address the challenges faced with 3-tier architecture or n-tier architecture and to provide a solution for common problems, like coupling and separation of concerns. There are two types of coupling -...
