Introduction ASP.NET SignalR is a new library for ASP.NET developers that makes developing real-time web functionality easy. SignalR allows bi-directional communication between server and client. Servers can now push content to connected clients instantly as it becomes available. Read more I will demonstrate how to implement dependency injection with Unity IoC container in a Signal R project. We will be building a simple online chatting app. Installing Packages To begin your journey to the world of realtime web apps, start by installing these packages: Unity IoC for DI Install-Package Unity Sever and client package for hosting with IIS and ASP.NET and Javascript client Install-Package Microsoft.AspNet.SignalR Server package for hosting SignalR endpoints Install-Package Microsoft.AspNet.SignalR.Core Client package .NET SignalR applications Install-Package Microsoft.AspNet.SignalR.Client Client package for javascript SignalR applications Install-Pack...

Introduction Have you ever wondered on how to get user location based on the network the user is currently on? Maybe you want to display the user country based on location or you want to disable some countries that shouldn't access your app, Your in the right place!!! freegeoip.net  provides a public HTTP API for software developers to search the geolocation of IP addresses. It uses a database of IP addresses that are associated to cities along with other relevant information like time zone, latitude and longitude. Let's see some codes in C#. C# Impelmentation 1. Create a Location class that will be used as a data transfer object. It will contain properties to hold the data return from the web service. 2. Call the  ReadAsync<T> method of  the HttpClient Class. The method will handle serialization of object to the response object. Let's play with it a little     if(currentLocatio...

Introduction lazy initialization  defers the creation of a large or resource-intensive object, or the execution of a resource-intensive task, particularly when such creation or execution might not occur during the lifetime of the program. In computer programming, lazy initialization is the tactic of delaying the creation of an object, the calculation of a value, or some other expensive process until the first time it is needed. To learn more about lazy initialization, check this out Why use it? When you have an object that has lots of data, but you only need some required data, the Lazy<T> class gives you access to load only specific data you need. It defers the creating of objects. It only initializes the object when needed It increases code performance The code The code here will be written in pure C#. Let's start with some basic console program. when you run the program, you will get "John Doe" as the result. Getting More Advan...

Introduction Implementing a payment gateway on your website in the past was so difficult and expensive. Most programmers when it comes to implementing a payment gateway they begin to do some equations on their mind like costs, security, and implementation. And not all payment gateway supports international transactions which is why some projects cannot scale easily. A solution for you In the last few years, tons of payment gateway has been bombing the internet and they have helped to streamline the process of implementation, costs, and security. Here are few providers: Paystack Interswitch web pay Cash envoy I used  Paystack  in one of my project written in Node JS to build an API that can handle payments.  Paystack  already has an API  to work with payments. To sign up for a test account, create an account with  Paystack  to get your public and secret keys and they are not very expensive to use. When your ready to go liv...
