C# 6.0–Dictionary Initializers

This blog post is part of C# 6.0 Features Series.

As we know c# 6.0 provides some cool new features and syntax sugar. Dictionary Initializers is one of them.  Till C# 5.0 we used to have collection initializers for collections but now C# 6.0 provides new way of initializing dictionary . This initialization features is available for there collections which supports index.

Following is a code for new way of initializing dictionary.

using System;
using System.Collections.Generic;

namespace DictionaryInitializer
{
    class Program
    {
        static void Main(string[] args)
        {
            Dictionary<int, string> Person = new Dictionary<int, string>()
            {
                [1] = "Jalpesh Vadgama",
                [2] = "Vishal Vadgama"
            };
            foreach (var person in Person)
            {
                Console.WriteLine("Key:{person.Key}, Value={person.Value} ");
            }
        }
    }
}

C# 6.0–Expression Bodied Members

This blog post is part of C# 6.0 Features Series.

There are lots of great features added to C# 6.0 and Expression bodied members are one of them. It’s provide great syntax sugar which will help you make your code more beautiful and readable.  In earlier versions of C# type definitions were always been tedious and we need to provide a curly braces and return type even if that function contains one single line. Expression bodied function will help you in such scenarios.

Let’s take a example to understand it. Following is a code to understand it.

using System;

namespace ExpressionBodiedMemebers
{
    class Program
    {
        static void Main(string[] args)
        {
            Person person = new Person
            {
                FirstName = "Jalpesh",
                LastName = "Vadgama"
            };
            Console.WriteLine(person.GetFullName());
        }
    }

    public class Person
    {
        public string FirstName { get; set; }
        public string LastName { get; set; }

        public string GetFullName()
        {
            return string.Format("{FirstName} {LastName}");
        }
    }
}

Understanding KRE,KVM,KLR and KPM in ASP.NET 5(vNext)

ASP.NET 5(vNext) is a new upcoming version of ASP.NET that Microsoft has redesigned from the scratch. Recently Microsoft has released Visual Studio 2015 Preview and with that they have released ASP.NET VNext.  In ASP.NET 5 (vNext) it comes with new runtime environment called KRE(K Runtime Environment) . With this version you can also run your application through command prompt using various commands. In this blog post we are going to learn about all terms related K Runtime Environment.

KVM(K Version Manager):

K version manager is one of the first thing you need to run command . KVM is responsible for installing and updating different version of KRE. It’s a PowerShell script used to get and manage multiple version of KRE being it on same time on same machine. So one application can now have one version of KRE and another application can have another version of KRE on same time. You can find more information at https://github.com/aspnet/Home/wiki/version-manager

Assembly Neutral Interface in ASP.NET 5(vNext)

CodeProject
Recently Microsoft has open sourced it’s entire ASP.NET next version stack on GitHub and I have been closely watching this for a quite a some time to understand how they have created architecture of it and how they organize everything in such a large stack.

I have seen  [AssemblyNeutral] attribute in few of interfaces and I was curious why it was required. So I dig into it and learned about it.

Why we need Assembly Neutral Interfaces?

In earlier version of ASP.NET and Microsoft.NET Interfaces are bind to a assembly where it is declared. Let’s say I have written a interface under DotNetJalps namespace for my framework.

namespace DotNetJalps
{
    public interface ILogger
    {
        DoAmazingStuff();
    }
}

Now after some time this framework is super popular and everybody loves abstraction I have created and now they wants same abstraction so there are two ways we can do this.

1. Convenience me to write this abstraction.
2. Write implementation themself and maintain that.

C# 6.0–String Interpolation

This blog post is part of C# 6.0 Features Series.

As we all know, C# 6.0 provides lots of small enhancements to the language and string interpolation is one of them. In this blog post we are going to learn how this small new feature can help us for string concatenation.

So let’s take small example, Where I have created a new example of string concatenation. Following is a code for that.

using System;
namespace StringInterpolation
{
    class Program
    {
        static void Main(string[] args)
        {
            string name = "Jalpesh Vadgama";

            //Old way of string concentaionation 
            Console.WriteLine("My name is" + name);
            Console.WriteLine("My name is {0}", name);

            //New way of doing this
            Console.WriteLine("My name is {name}");
        }
    }
}

C# 6.0–Exception Filters

This blog post is part of C# 6.0 Features Series.

C# 6.0 contains lots of small features and one of them is Exception filters. It is already there with VB.NET earlier but now it is available in C# also. In exception filters now if exception is combined with Exception statement and If condition of if satisfy then it will execute that block.

Let’s take a simple example to understand it better. Following is a code for a simple console application. Before exception filters we were able to write a code like following.

using System;

namespace ExceptionFilters
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                throw new Exception("Jalpesh");
            }

            catch (Exception ex)
            {
                if(ex.Message =="Jalpesh")
                    Console.WriteLine("Exception with Message Jalpesh is executed");
                else
                    Console.WriteLine("Exception with Message DotNetJalps executed");
            }
        }
    }
}

In above example, I have thrown a exception in try block and in catch block I have written if-else block to check message and based on that it will print some method.

C# 6.0–Null conditional operator

This blog post is part of C# 6.0 Features Series.

As we know there are lots of small features added in C# 6.0 and Null conditional operator is one of them. You can check null with specific conditions with Null conditional operator and this will definitely increase productivity of developers and there will be less lines of code.

Let’s create example. Following are two classes I have created for this example. Address class will contains two properties like Street and City.

namespace NullConditionalOperator
{
    public class Address
    {
        public string Street { get; set; }
        public string City { get; set; }
    }
}

And Same way Person class contains four properties Id,FirstName,Lastname and Address which is of type Address class which we have created.

C# 6.0–Static class using statement

This blog post is part of C# 6.0 Features Series.

C# 6.0 version introduced lot of small features and one of that features is  using feature. Now with C# 6.0 you can use using statement which was not possible in earlier versions of  C#. Following is a example of using statement in C#.

using static System.Console;

namespace StaticClassUsing
{
    class Program
    {
        static void Main(string[] args)
        {
            WriteLine("With using statement");
        }
    }
}

And below is output when you run your application.

C# 6.0–Auto implemented property initializer

This blog post is part of C# 6.0 Features Series.

As we all know C# 6.0 is there in preview mode and Microsoft has added few small features to C# 6.0 which helps  lot while you develop application. In today’s blog post we are going to learn one more small feature called “Auto implemented property initializers”.

Developers working on C# used a automatic properties a lot and there has been lot of demands from developers that automatic properties should a have initializers and Microsoft has listened to that feedback and with C# 6.0 it has been introduced. So now we don’t have to use constructors to initialize automatic properties and there will be less and much cleaner code for Automatic property initializations.

Colorized tooltip in visual studio 2015

Visual studio 2015 provides lots of new features and Colorized tooltip is one of the features that I really like. As we all know that Visual studio supports automatic collapse of various language constructs like classes, methods.  When you mouse hover it automatically show hidden code presented in that portion.

In earlier version of Visual Studio that tooltip was shown with hidden code but it was in plain text. Now this tooltip is colorized with syntax highlighting so your hidden code is more readable.It’s look like below.



Hope you like it. Stay tuned for more. I’m going to post lot more blog post about new Visual Studio 2015 features.

C# 6.0–nameof Operator

This blog post is part of C# 6.0 Features Series.

Microsoft announced the new version of C# 6.0 at the day of visual studio connect event on November. They have not added any big features to C# 6.0 but they have listened to community and added few small features which comes really handy. One of the that is nameof operator.  In this blog post we learn why nameof operator is very useful.

Let’s create a class Employee with few properties.

public class Employee
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

Now what I want to do here is to create a object with object initializer and print values of properties with print method.

Custom Windows Layout in Visual studio 2015

Visual studio 2015 preview has been released by Microsoft before some days. So I recently got installed in my machine. It contains a bunch of new features and we are going to explore it one by one. Custom layout windows in visual studio 2015 is a one of the nice features in list. In this blog post we are going to learn about custom windows layout in Visual studio 2015.

As we all use different kind of devices like laptop, desktop and some times we choose our visual studio layouts based on screen size and resolution of monitors.   We generally moved items like solution explorer, Team explorer and toolbox based on space available and resolutions of devices. Personally When I work on desktop where I have 22 Inch monitor I used to prefer my solution explorer and other windows open while when I work on laptop which got 15 inch screen all the windows will be in collapse mode.  In this kind of scenario this features comes quite handy.

Let’s see how its works. Here’s is my laptop layout where I like all the windows in collapse mode and I will open windows as I need them.

Continuous integration with visualstudio.com and TFS

CodeProject
As a developer, we all are using some kind of source control provider to maintain versions of our source code.  But another aspects of source control to is to make sure that code committed in source code repositories are  perfect and it will not break the build of particular software. That’s why Continuous integration is very much popular this days.

What is Continuous Integration:

As per wikipedia

Continuous integration (CI) is the practice, in software engineering, of merging all developer working copies with a shared mainline several times a day. It was first named and proposed by Grady Booch in his method, who did not advocate integrating several times a day.

In simple words, when developers checks in or commit code to source code repository a build of software will automatically triggers to check whether current check-in/commit of code breaks code or not.

Singleton Instance in SimpleInjector

Before some time I have written a blog post Dependency Injector with Simple Injector. This is a second blog post in same series. In this blog post we are going to learn How we can create a singleton Instance in Simple Injector.

What is is Singleton:

This is one of the Gang of Four creational pattern. Idea of behind the singleton pattern is to have only one instance of class of at anytime. This pattern ensures that a class will has only one instance of it and provides a global point of access to that instance.

I have already written a global blog post about that. You can find a basic example of Singleton pattern in C# from the following link.

Singleton Class in c#

How we can create Singleton Instance with SimpleInjector:

Here I’m going to create a console application with logger example. So let’s create via creating a new project like below.
