Visual Studio 2015 Github tools

I love open source and that’s why I’m making all the source code of my blog post on Github. Now with Visual studio 2015 RC Microsoft and Github released a GitHub tools for visual studio. So now you can directly interact with your Github repositories from team explorer itself. Working with Github never be easy now.

Once you install, Github tools for Visual studio with visual studio 2015 installation. It will be available on Team explorer like below.

How to create a storage account with new azure portal:

So what we are waiting for let’s start our walk through of creating a storage account with new portal. So once you put url in browser it will be ask for login with your azure live account.

Structure and Operator overloading in C#

Recently I have been playing with structure and It’s fun. In this blog post we are going to learn how we can use operator overloading with structure in C#.  You can find my blog post that I have already written about structure  at following location.

Structure in C#
Structure with constructor in C#
Structure with Interface in C#

So as usual I've created a console application to demonstrate operator overloading in C#. Here I have created a structure with equals operator overloading and following is a code for that.

Structure with Interface in C#

Recently I have been playing with Structure and it is fun. I have written couple of blog post about structure. Following are links for that.

Structure in C#
Structure with constructor in C#

In this blog post we are going to learn how we can use structure with interface. So like earlier example I’ve created a console application. Now it’s time to write interface which we can implement with structure. Following is a code for that.

using System;

namespace StructureWithMethodAndInterface
{
    interface IPrintable
    {
        void Print();
    }
}

Here you can see that I have simple interface IPrintable which has simple print method. Now let’s create a structure which implement this interface. Following is a code for that.

Structure with constructor in C#

Before some time , I have written basic introduction post about Structure in C#. In this blog post we are going to see how we can have constructor with Structure. As we all know structure is a value type so it stored on stack. So let’s create a structure like follow with constructor.

public struct Customer
{
    #region Fields

    public int CustomerId;
    public string FirstName;
    public string LastName;

    #endregion 

    #region Constructor

    public Customer(int customerId, string firstName, string lastName)
    {
        CustomerId = customerId;
        FirstName = firstName;
        LastName = lastName;
    }

    #endregion
}

Here you can see I have created Stucture with parameter. As we all know structure is a value type so when initialize the it at that time we need to give values to its elements so that’s why default constructor without parameter is not supported in C#.

Structure in c#

In this blog post we are going to learn about Structure Data structure in C#. In C# Structure is value type which stores on Stack. It is a composite value type that contain other types. You can also create object of structure like class. In C# structure can  contains fields, properties, constants, constructors, properties, Indexers, operators and even other structure types.

So enough theory. Let’s create a sample console application to learn about structure.

There are lots others are also available but I think it’s if you follow and practice above mentioned resources your code will be perfect.

Entity Framework Internals: Connection Resiliency

When you use cloud services to deploy your application and database it might be possible that transient connection will be a problem between database server and web servers. When you use on premise servers that uses the database server and web server on same data centre. When you use cloud there will be huge infrastructures and you never know where it is deployed even if it deployed on same data centre there will more connection like network load balancers etc. When you use cloud services that will be shared by lots of users which means its responsiveness can be affected by them. And your access to the database might be subject to throttling. Throttling means the database service throws exceptions when you try to access it more frequently than is allowed in your Service Level Agreement (SLA).

So in cloud service there will be transient problems which will be resolved in short period of time. So when you got such kind of errors then you can wait for some time and then you have retry. For that kind of operation Entity Framework provides connection resiliency feature.

The connection resiliency features must be configured for proper database services. It has to know which exceptions are likely to be transient problem and which exceptions are caused by our code. It has to wait for an appropriate amount of time between retries of failed operation. Also it has to try number of times before giving up.
