Don't worry. Not everyone knows it...

Recently, one of my colleague asked me, which WCF template should I use to create a service? For experienced people, it may be a silly question, but it is one of the common question among beginners, who just entered into the world of services. That’s the motivation who made me write this small post. Well, let’s first have a look at what all templates are available in Visual Studio 2015 for WCF:  The developer can choose any of the above templates as per project need. Let’s go through them one-by-one. WCF Service Library: This template is nothing but a simple service library which uses App.config as its configuration file. WCF Service Application: This template will create a web site which in turn will be hosting a service in it. Here Web.Config will be used to serve configuration settings. WCF Workflow Service Application: This template is useful when you want your workflow to be accessed as a web service. Syndication service Library: Thi...

First of all, a very-very Happy New Year to all my readers. If you are reading this post, then I’m assuming that you have a working experience of WPF using MVVM.  Don’t worry, I’m not going to re-write a huge post on what MVVM is and where to use it? This blog is very small which talks about one of the best practices any developer implementing MVVM should follow. Well, let me provide you the context first. Last week I was going through one of my colleagues’ code and noticed few interesting things in his ViewModelBase class: It was holding few Dependency properties  It was inheriting  DependencyObject  How it sounds to you? Good or … ?  Of course, that is not at all a good practice as ViewModelBase is the base class for all the ViewModels and is not supposed to contain such code. Well, this is not the only reason.  There are many other reasons which are making this implementation a BIG NO.  1 st Reason – A DependencyObject was ...

This is my last blog of year 2016. I just want to take a minute to say thank you to all my readers who reads my blog. It’s prodigious erudition with you all. I wish you all a very Happy New Year and a great beginning. Catch you all in next year with same zeal :) 

Recently I received a query from one of my friends stating that access key is not working in his WPF project when he is using ContentPresenter. So, I thought to share a post on it as it may be helpful for other reader also. Before digging directly into the problem, first let’s see what happens when access key is set directly on the Content property of a WPF Button. Below is my code for setting a Content on a Button: < Grid >         < Button Height ="39" Width ="100" Content ="_Save"/> </ Grid > If you will run your application with above snippet, you will notice that there is no underscore coming in front of word Save. But as soon as you press ALT key, underscore comes up. Which is an expected behavior :) Now tweak the code a bit and instead of setting content directly on a button, do it on ContentPresenter as shown below: < Grid >         < Button Width ="9...

Nowadays one of the most popular question is ‘Can ASP.NET Core be chosen over ASP.NET MVC?’ So, to answer this question, let’s have a look at .NET architecture diagram:  By looking at above diagram, one can easily see that .NET framework is used develop desktop Windows applications using WPF and Windows Forms and Web applications using ASP.NET MVC. .NET Core supports UWP and ASP.NET Core libraries, in which UWP is used to create Windows 10 apps and ASP.NET Core is used to build Web applications for Windows/Linux/Mac operating systems. Now regarding what has to be chosen and when has to be chosen, I need not to re-invent the wheel because Jeff has written a very good article on it at ‘’Should I use ASP.NET Core or MVC5?’. Hope you find this post useful.

Let’s have a look at one of the coolest feature of Visual studio 2017. If you will see below snapshot, there are many new icons here.  These icons are part of cool new feature called Live unit testing in Visual Studio 2017 Enterprise. Live Unit Testing continuously runs and displays unit test result and code coverage inside editor itself. It automatically finds and runs impacted tests for every line of code. In above diagram, Red cross indicates failed test case, Green tick indicates passed test case and Blue minus indicates the code that have no test coverage at all. Let’s start by looking at failing test case. You can quickly navigate to failing test case by clicking on tooltip as shown below:  And below is my test case: At this point, I’m not really sure why this is failing. So, I’ll go ahead and debug this test We can see here that above particular code has thrown a nul...

Two things play a very significant role in any application development, and those are application’s footprint and performance. Whenever I’m asked to work on these two tracks, I used to visit a huge list of sites to get many more ideas apart from what I already know. So, I thought, why can’t I collate all the good points and add them to my repository. At the same time, I thought of sharing those points in this blog. Rather than making this blog post full of theory, I’m planning to make it simple by just adding the bullet points. Uhh! Enough of gossip. Let’s get started by going through some common and important rules. Create object only when it is really required More the objects lesser the performance :(  Grab resources, use them and release at the earliest Default capacity of StringBuilder is 16. So, if you want to store less than 16 values then make sure to set the capacity. Avoid unnecessary boxing and unboxing Prefer lazy loading Use Static variables cautiou...
