Convert C# Object into JSON and vice versa using Jil

I have also written couple of posts about converting C# object into JSON and vice versa. Following is a list of post for the same.

Converting a C# Object into JSON string
How to convert C# object into JSON string with JSON.NET

In this blog post we will learn about how we can convert C# object into JSON with Jil- Fast .NET JSON (De)Serializer, Built On Sigil an open source library by stack exchange team.

What is Jil:

Jil is a open source (De) Serializer library written by Kevin Montrose and stack exchange team. It is built on Sigil- with a number of crazy optimization tricks.Sigil is also a custom fast validation helper for .NET CIL Generation. Jil is one of fastest Serializer and deserializer library. It is also open source. You can find more information about at following link.


So let's create example which demonstrate both Serializing and Deserializing object. So first we will create JSON string from C# object via serializing with Jil and then we again deserialize that string to C# object. I'm going to create a console application for this.


After creating a application first thing we have to do is to add Nuget package from JIl via following command.


I'm going to use a Employee class for this example which have four properties Employee Id, First Name, Last Name and Designation.
namespace CsharpJSON
    public class Employee
        public int EmployeeId { get; set; }
        public string FirstName { get; set; }
        public string LastName { get; set; }
        public string Designation { get; set; }
Then I have created a function Get Employee function to initialize Employee class with some data.
private static Employee GetEmployee()
    var employee = new Employee
        EmployeeId = 1,
        FirstName = "Jalpesh",
        LastName = "Vadgama",
        Designation = "Technial Architect"
    return employee;
Now it's time to serialize that employee class into JSON string so I have created  Serialize Employee function.
private static string SerializeEmployee(Employee employee)
    using (var output = new StringWriter())
        return output.ToString();
Here you can see I have use JSON.Serialize function which serialize C# object into string writer. Same way I have created Deserialize Employee function to deserialize JSON string created by previous function.
private static Employee DeserializeEmployee(string employeeString)
    return JSON.Deserialize<Employee>(employeeString);

Here you can see I have used  JSON. Deserialize function to convert JSON string into C# object. Finally I have called this function in my console application Main method and print it with Console.Writeline method.
static void Main(string[] args)
    var employee = GetEmployee();
    string employeeSerializedString = SerializeEmployee(employee);

    Console.WriteLine("Serialize Employee");

    Console.WriteLine("\n\nDeserializing Employee");
    var employeeDeserialized = DeserializeEmployee(employeeSerializedString);



Now when you run application it will generate output like following.


You can find complete source code of this application at following location on GitHub-

Hope you like it. Stay tuned for more!

How to create Rest API(Web API) with ASP.NET Core 1.0

Recently Microsoft has released ASP.NET Core 1.0 RC2, I am getting lots of request from readers that about creating Web API. So I thought it will be a good idea to write a blog post about how to create Rest API(Web API) with ASP.NET Core 1.0.

So let’s get started via creating an ASP.NET Core 1.0 Web Application like following.

Once you click on ASP.NET Web Application, It will ask whether you need to create Web Application or Web API application. We are going to Web API so I am going to select Web API Application like following. Please note that in ASP.NET Core 1.0 there is no separate libraries or DLLs required for creating web APIs. This is just a project template.

Now once you click on OK It will create a Web API application with default values controller and program.cs.  As you know Program.cs is now starting point for the ASP.NET Core 1.0 application so It contains all the required configuration and startup items. Following is a code for that.

How to use migration with Entity Framework Core

Entity framework core is  the lightweight, extensible and cross-platform version of Entity Framework. Before some time, Microsoft has Released a new version of Entity Framework RC2. I have written a couple of blog post about Entity framework code first migration earlier for Entity framework 6.0. So there was a couple of request coming for writing a blog post about Entity Framework Core RC2 migration. So I thought it will be a good idea to give an overview how database migration works in Entity Framework Core RC2. This post will cover a basic scenario where we are going to create the database with existing ASP.NET Identity migration and then we are going to create a new model and have that migration applied in the database.

How to use Entity Framework Migrations: Let’s get started, To demonstrate entity framework core migrations, I am going to create a sample core web application like following.

Once we select core application it will appear the following dialog.
