Dependency Injection Using Unity – Resolve Dependency Of Dependencies

This article will not be very theoretical, but would be more of a tutorial to showcase the existing problems with tightly coupled applications, how to make the application loosely coupled and achieve inversion of control via dependency injection.

Introduction

Inversion of control (IOC) and Dependency Injection (DI) work hand in hand and makes our application more loosely coupled and easy to expand. It is strongly recommended to follow SOLID principles when it comes to development. This article will not be very theoretical but would be more of a tutorial to showcase the existing problems with tightly coupled applications, how to make the application loosely coupled and achieve inversion of control via dependency injection, solve the problem of resolving dependency of a dependency in a three-layered/n layered project architecture using unity framework. You can get the downloadable source code at the end of the article.

Singleton Design Pattern In C# – Part Three (Static vs Singleton)


Introduction

In this series on learning singleton pattern, we learned lazy initialization and eager initialization with practical examples. We also learned why it is necessary to make the singleton class sealed with the sealed keyword. In this article, I’ll try to explain the differences between static and singleton class. We will also see where to use static class and where to use singleton classes.

Singleton Design Pattern In C# – Part 2 (Eager and Lazy Initialization in Singleton)


Introduction

In the previous article on learning singleton pattern, we discussed what is singleton design pattern, when is it needed and what problems it solves. We also discussed how to create a basic singleton class step by step and how to enhance that class to be thread-safe with the help of locking and performance effective with the help of double check locking. In this article, we’ll discuss Lazy initialization, the lazy keyword, why to make singleton class a sealed class, and what are the differences between singleton and static class. Before we start, I strongly recommend you go through my last article.

Singleton Design Pattern in C# – Part 1


Introduction

I always wanted to write on Singleton design pattern in C#. Though there already are many posts available on Singleton design pattern, I’ll try to cover this topic in the most simplistic and easy to understand way.

Create API with ASP.NET Core (Day 4): Working with Serializer Settings And Content Negotiation In ASP.NET Core API


Introduction

This article of the series “Web API with ASP.NET Core” will focus on topics like serializer strings and content negotiation. We learned how to deal with HTTP Status Codes and return sub resources in ASP.NET Core in last article and paused at Serializer Settings. We’ll continue to explore the importance of status codes and practical examples as well. We’ll also explore resource creation and returning the child resources as well in this article. We can use the same source code as we got at the completion of last article of the series.

Create API with ASP.NET Core (Day 3): Working With HTTP Status Codes In ASP.NET Core API


Introduction

This article of the series “Web API with ASP.NET Core” will focus on topics like returning HTTP Status Codes from API, their importance, and returning sub resources. We learned how to create an API in ASP.NET Core and how to return resources, in last article, and paused at Status Codes. We’ll continue to explore the importance of status codes and practical examples as well. We’ll also explore resource creation and returning the child resources as well in this article. We can use the same source code as we got at the completion of last article of the series.
