In the previous post, we have been talking about Builder and the Fluent Builder design patterns. So, we strongly recommend reading that one before you continue with this post if you are not familiar with the Fluent Builder pattern. In this post, we are going to get a...
The Builder design pattern is a creational design pattern that lets us create an object one step at a time. It is quite common to use this pattern when creating a complex object. By using this pattern, we can create different parts of an object, step by step, and then...
The basic idea behind the Dependency Inversion Principle is that we should create the higher-level modules with its complex logic in such a way to be reusable and unaffected by any change from the lower-level modules in our application. To achieve this kind of...
The Interface Segregation Principle states that no client should be forced to depend on methods it does not use. So, this is the basic definition which we can read in many different articles, but what does this really mean? Let’s imagine that we are starting a new...
The Liskov Substitution Principle (LSP) states that child class objects should be able to replace parent class objects without compromising application integrity. What this means essentially, is that we should put an effort to create such derived class objects which...
The Open Closed Principle (OCP) is the SOLID principle which states that the software entities (classes or methods) should be open for extension but closed for modification. But what does this really mean? Basically, we should strive to write a code that doesn’t...
While developing a project, we strive to write maintainable and readable code (besides the working part 😀 ). To accomplish this, each and every class should do its own task and do it well. Yes, it is quite important for a class to have no more than one task. If it...
SingalR is a library that helps us provide real-time web functionality to our applications. This means that our server can push data to any connected client as soon as that data is provided, in real-time, and vice versa. In this article, we are going to show you how...
One of the most important components in Angular Material is the input component. Angular Material supports different types of input elements like color, date, email, month, number, password, etc. In this article, we are going to use the input components to create a...
In this article, we are going to create the error pages and the details component. The main focus will be on the material components. We are going to create the Not-Found component, the Server-Error component, and finally the Owner-Details component. Through these...
We are going to divide this article into two major parts. The first part will consist of creating environment files, HTTP repository service, and creating a new Owner module with the lazy loading feature. As you can see, everything is Angular specific, so we won’t...
In this article, we are going to talk more about delegates in C#. A delegate is a reference to a method. We can use a delegate object to pass it to the code in which we want to call a referenced method, without knowing at compile time which method will be invoked....
In this article, we are going to talk more about Generic List and Dictionary in C#. A List<T> and Dictionary are very useful collections in C#, and we are going to discover its features in the rest of the article. Classes and Constructors Properties Static...
In this article, we are going to talk about the queue, stack, and hashtable collections in C#, how to use them and how to use the methods they provide. Classes and Constructors Properties Static Members, Constants, and Extension Methods Anonymous and Nullable Types...
In this article, we are going to show you how to prepare our Angular project and how to install Angular Material in a few simple steps. But first things first. Before we start with the Angular Material features, we need to create the project first. So let’s dive right...
C# provides generics to help us remove the need for casting, to improve type safety and make it easier to create generic classes and generic methods. Classes and Constructors Properties Static Members, Constants, and Extension Methods Anonymous and Nullable Types...
Different classes may implement the same interface, and that is the common case in software development. What is common as well is that the method from that interface can have the same implementation in those classes. That could be a signal that we are doing something...
Inheriting from a class is a powerful mechanism, but the real inheritance power comes from an interface. An interface provides the members that a class that inherits from an interface must implement. We can look at the interface as a contract which states that a class...
