Unit of Work in Repository Pattern
Unit of Work is the concept related to the effective implementation of the repository pattern. non-generic repository pattern, generic repository pattern. Unit of Work is referred to as a single transaction that involves multiple operations of insert/update/delete and so on.
How To Switch From Factory Method Pattern To Abstract Factory Pattern
This article will also compare and the difference between Abstract Factory and Factory method pattern. I am using the same case study example so that difference can be identified between these two design patterns.
Object Pool Design Pattern
In this article you will learn hoe to use Object Pool Design Pattern.
Command Design Pattern
Command design pattern is part of Behavioral Design Patterns from Gang of Four(GoF) Design Patterns. Behavioral Design patterns concerned with communication Between Objects. It is used to cover/envelop a request as an object and pass to a User. A user doesn’t know how to service the request but use encapsulated command object to perform the action.
Session Facade Design Pattern
In developing software its very important to use proper design patterns,In learning design patterns its important to Observe which design pattern properly fit on our problem and how we use appropriate patterns..its usual to misuse design patterns on problem.so its very important to finds a proper design pattern on a given problem in software development.
Design Patterns From The Beginning - Day Two
In the second part of my design patterns articles series, we are going to learn about the classification of design patterns according to the nature of the design problem they solve.
Design Patterns From Beginning - Day One
A software developer will make software/application to solve or achieve the requirements of a Company or An Organization Using different programming language.In Application development developers might use different language or frameworks like c++, c#, Java, Php, javascript, Python, Ruby on Rails etc.
Observer Pattern - Implementation In .Net Framework
This article describes the Observer pattern and the interfaces .Net Framework provides.
Breaking Circular Dependency Between Components
Couple of days ago, I came across a piece of code that was not just tightly coupled but also formed a circular dependency among the components. In this article, I've tried to give you a gist of it along with a solution for breaking the dependency.
Understanding State Design Pattern By Implementing Finite State Machine In Super Mario Game
In object oriented programming State Pattern is one of the way to implement Finite State Machines. This pattern falls under Behavioral Design Patterns.
Learn About Static VS Singleton
Compare C# static classes and the Singleton pattern, including lifetime, inheritance, state, and a shopping cart example with one instance per customer.
Improving Efficiency With Strategy Design Pattern In JSON Parser Example
Here we will see how Strategy Pattern helped in refactoring code in JSON parser example
Difference Between Software Design Principles - DRY And KISS
In this article, we will explain the main basics of two software design principles, DRY and KISS.
Leveraging Template Method Design Pattern In Logger Example
Here we will understand the use of Template Method Design Pattern by gradually refactoring our code.
Singleton Implementation With Real World Example
This article describes different ways of singleton pattern implementation and how to make the singleton class thread-safe. I have described with real time problem and given a reference of source code as well
Composed Relationship Types - Func<Owned<T>>
It's the beauty of relationship types, that they can work in conjunction with one another. Therefore, we can compose relationship types to solve a particular problem.
Separation Of Concern And Data Access From Within Code
Learn how to separate data access from business logic using the Repository and Unit of Work patterns with Entity Framework.
Func<T> - Dynamic Instantiation
The article talks about scenarios where we want more than one instance of a given service
Owned<T> - Controlled Lifetime In Dependency Injection With Autofac
Generally speaking, an owned dependency corresponds to some unit of work performed by the dependent component.
Dependency Injection - Part Five - Using A DI Container (Autofac)
A DI container takes the responsibility of instantiating and providing the dependency instances, irrespective of the level of dependencies. As a result, it is a container that manages the scope of the instantiated objects.
Direct Dependencies And Enumeration
In this post, we will be talking about the two most commonly used types of relationships, namely, direct dependency relationship and enumeration.
Using Lazy<T, TMetadata> In Dependency Injection
Lazy<T,TMetadata> is a type provided by MEF to hold indirect references to exports. Here, in addition to the exported object itself, you also get export metadata, or information that describes the exported object.
Dependency Injection - Part 7 - Service Locator Pattern
Service locator pattern is one of the most commonly used patterns. In general, this pattern is used along with other patterns like Adapter Pattern, Observer Pattern, Dependency Injection Principles and many more. In this post, however, we will be talking about its use with dependency injection, which is one its many uses.
Dependency Injection - Part Six - Autofac's "AsImplementedInterfaces"
While I was exploring Autofac, I found AsImplementedInterfaces quite interesting. Not only because it is useful, but also because if we are not careful with its use, we may end up with unexpected application behavior.
Design Patterns Simplified - Strategy
This article explains what Strategy Design Pattern is and how to use it in software design and development.
Dependency Injection - Part Four -Embracing Abstraction
Dependency Injection (DI) is a technique that helps us achieve loose coupling between objects and their collaborators. In this post, we will use constructor based dependency injection, however, we are not going to use any DI container for now.
Overview Of Strategy Design Pattern
In this article, we will learn about Strategy Design Pattern.
