In today’s article I would like to briefly discuss one of the commonly used design pattern in software engineering which is Singleton Pattern. Singleton pattern is usually being used if you are creating a system that only needs one instance of a class and that instance will be used throughout the lifecycle of the application. Common scenarios of using Singleton pattern is for logging, database access, etc.
Xamarin: GETTING STARTED WITH PRISM 6 (PART 2) – Command
For the second part of this Getting started Xamarin with Prism series, I would like to discuss on how to use Command in Xamarin forms. By the way if you missed the Part 1 of this series you can check this article.
When you say Command, for example in Win Forms it’s just an event that was fired
due to let’s say a button click or an event brought by textbox lost/on focus but in Xamarin
Commands are just methods that are directly binded from your view e.g. (Button, MenuItem, ToolbarItem) and executes the binded method in your ViewModel.
Xamarin: Getting Started With Prism 6(Part 1)
In today’s article I will discuss about the basic requirements you need to perform for running Xamarin Forms with Prism 6 framework. So what is Prism by the way, Prism is a framework which originated as a XAML application framework mainly during the early days of WPF. It was previously maintained by the Patterns and Practices division of Microsoft prior to becoming an open source platform. Here are the following features we can get for implementing Prism in our Xamarin forms:
C#:Basic Azure Storage Table Operations
Last time in our discussion on creating Azure storage table, using our developer’s account, we have successfully deployed our Azure storage using the M.S. Azure portal. We also used a tool called Azure Storage Explorer in creating our sample Table which also contains sample Entities. For today’s article I will teach you on basic operations, e.g. (Insert, Select, delete) you can perform on your Azure Storage using a C# Console application.
Visual Studio 2015: Code Metrics
Many of us programmers have the mentality that it’s just okay to implement codes in anyway as long as it is running. Well to tell you the truth you should already change or move away from that kind of mindset. Software development has its own guidelines like abstraction, refinement, modularity and other same concepts that you can use to guide you during coding and avoid the so-called programming pasta. One tool I use in Visual Studio 2015 is Code Metrics. For today I will show you how to generate Code Metrics on your project. Then I plan to discuss deeper on the different code metrics in the next succeeding articles.
Visual Studio Dev Essentials
Do you want to have the latest tools for application development, free training and access to Cloud Service then good news last November 2015 Microsoft launched a program called Visual Studio Dev Essentials program where in they provide great tools for apps development, apps deployment and also some free access to on demand training like Xamarin and Pluralsight. One good thing about this program is that it’s all free you just need to have an Microsoft Account as login credentials then that’s it you are good to go. Today I will discuss on how to join the program and run through some of the tools and services that they currently offer.
