CRUD Operation with ASP.NET MVC and Fluent Nhibernate.

Before some time I have written a post about Getting Started with Nhibernate and ASP.NET MVC –CRUD operations. It’s one of the most popular post blog post on my blog. I get lots of questions via email and other medium why you are not writing a post about Fluent Nhibernate and ASP.NET MVC. So I thought it will be a good idea to write a blog post about it.

What is Fluent Nhibernate:

Convection over configuration that is mantra of Fluent Hibernate If you have see the my blog post about Nhibernate then you might have found that we need to create xml mapping to map table. Fluent Nhibernate uses POCO mapping instead of XML mapping and I firmly believe in Convection over configuration that is why I like Fluent Nhibernate a lot. But it’s a matter of Personal Test and there is no strong argument why you should use Fluent Nhibernate instead of Nhibernate.

Fluent Nhibernate is team Comprises of James Gregory, Paul Batum, Andrew Stewart and Hudson Akridge. There are lots of committers and it’s a open source project.

You can find all more information about at following site.

http://www.fluentnhibernate.org/

On this site you can find definition of Fluent Nhibernate like below.

Fluent, XML-less, compile safe, automated, convention-based mappings for NHibernate. Get your fluent on.

They have excellent getting started guide on following url. You can easily walk through it and learned it.

ASP.NET MVC and Fluent Nhibernate:

So all set it’s time to write a sample application. So from visual studio 2013 go to file – New Project and add a new web application project with ASP.NET MVC.

Different way of mapping with EFCodeFirst

Recently I have been working Entity Framework Code First 6.0 and it’s awesome. I am in love with it. It has got great fluent API and we can do anything with that. It’s also promotes Convention over configuration which I love so far.

I have seen people are more confused about how we can map table to class via Entity framework via code first. So this post is going to be in same series. In this post I’m going to write about different ways to mapping table to class. I have already written two post about in details.

Entity Framework code first and Inheritance–Table per hierarchy
Entity framework code first and inheritance- Table Per Type

In this blog post I will give you tips and tricks to map class(type) with database table.

HashSet in C#

In this blog post we are going to learn about HashSet collection in C#. It is a cool collection available from C# 3.5. Like any other collection it can be used for representing a set of value. It is an optimized set collection. It helps eliminating duplicate string or elements in collection. Whenever an Item is added in collection it will check whether this items are already there in collection If not then only it will add items.

Let’s take an example for the same.

using System;
using System.Collections.Generic;

namespace CSharpHashSet
{
    class Program
    {
        static void Main(string[] args)
        { 
            HashSet<string> nameHashSet=
                new HashSet<string>
                {
                    "Jalpesh", "Vishal", "Tushar", "Jalpesh"
                };
            foreach (var item in nameHashSet)
            {
                Console.WriteLine(item);
            }
            Console.ReadKey();
        }
    }
}

Now if you see the code carefully I have created HashSet of name(string type) with duplicate name like “Jalpesh” and then enumerate that collection with for loop and print items of collection with Console.WriteLine.

StructureMap–Getting Started

In this post we are going to learn about How we can do dependency injection with StructureMap. Here we are going to take a sample application of shopping cart. This shopping cart can process two type of orders 1. Sales order 2. Purchase Order. We want an abstraction for this. So first we are going to create an interface IOrder which will be implemented by both Purchase Order and Sales Order classes.

Following is a code for that.

public interface IOrder
{
    void Process();
}

And following is a implementation of SalesOrder class.

public class SalesOrder : IOrder
{
    public void Process()
    {
        Console.WriteLine("Sales Order Processed");
    }
}

Same way following is a implementation of PurchaseOrder class.

public class PurchaseOrder : IOrder
{
    public void Process()
    {
        Console.WriteLine("Purchase Order Processed");
    }
}

And following is a code for Shopping Cart.

public class ShoppingCart
{
    private readonly IOrder _order;
    public ShoppingCart(IOrder order)
    {
        _order = order;
    }

    public void CheckOut()
    { 
        _order.Process();
    }
}

Entity Framework Code First migrations

In this blog post we are going to learn about entity code first migrations. Entity Framework code first approach will allow you to define model classes as per the domain requirements via POCOs. Hence you have complete control over classes are written. But as application grows and there are some new features to be added and  your classes will change. Entity Framework Code Migrations allows you to handle this migrations.

As we all now that Entity Framework Code First approach allows you to create database based on your classes created. It’s provide you three types of initializers.

CreateDatabaseIfNotExist: This is the default initializer which will create classes if database not exists.

DropCreateDatabasesWhenModelChanges: This initializer is only good when you don’t concern about your database records. If there is any change in class then it will match database will classes and if there is any difference then it will drop and create a new database.

DropCreateDatabaseAlways: This initializer will always create new database whether database exist or not. If database exist then it will drop that database and create it again.

Visual Studio 2013, Team Explorer and BitBucket

With Visual Studio 2013, Microsoft started supporting Git directly with Team Explorer  and I have written a blog post how we can use git with team explorer and github called Visual Studio 2013, Team Explorer and GitHub. This post gained lots of popularity and also get lots of email about writing a blog post for using Git With BitBucket.org which is similar kind of source code hosting service like GitHub.com. So this post is all about it.

In this post I’m going to use a sample console application where we will put some code and then publish it to BitBucket Git Repository.  In this post I’m going to slightly take different approach then previous post but still you can do same way also previous post also.

In this post first we are going to create repository in BitBucket and then clone it on local. So here people will also get to know how we can create and clone a repository in local.

How to create repository in BitBucket:

If you don’t have account in BitBucket.Org then you need to create a account in BitBucket. You can create account from the following link.

How to convert PSD into image file in c# with Magick.NET

Recently in one of project we had a requirement of converting a Adobe Photoshop file (PSD) into image file(.png) file. After digging while on internet I have found a great library which has so many features in can easily convert PSD files into any time of image file.

The Library is Magick.NET. It’s a open source project you can find more information about it from the following codeplex link.
https://magick.codeplex.com/

There are lots of example available for image conversion and other image editing functions. You can find that about that on documentation.
https://magick.codeplex.com/wikipage?title=Convert%20image

There are lots of NuGet package are available also. Following is a one of them.
