Create C# classes using a JSON response

Assume you have a JSON access point and the response is like below(This is accessed via Fiddler).
Copy that JSON response and format it using a JSON viewer. In this demo I have used http://jsonviewer.stack.hu/.
Copy the code snippet as highlighted.
Create an empty class file in Visual Studio.
The you can paste the JSON code as classes like below.
The created classes will be look like below.

Change the JSON serialization which follows the Camel Case notation

In software coding, we must follow the naming conventions. In C#, first letter of the property name should be capitalize. But in JavaScript first letter should not be capitalize.

If we create a default ASP.net Web API project, above naming conventions will be ignored.

In the following demo I will show an example how we will get a JSON response in default Web API project and how we can configure the project to have correct naming conventions.

First create a ASP.net Web API project.
Add School and Student classes to the model folder. Add an empty Web API controller called StudentsController to the controllers folder.
Content of the Student class should be like below
Content of the School class should be like below.
In the StudentsController add an Web API action method like below.
Then run the project and check it in the Fiddle.
You will see the JSON naming conventions are not there. All field names are according to the C# classes.
For the correct naming conventions we must add a new configuration to the WebAPiConfig class. You have to use CamelCasePropertyNamesContractResolver class.
Again run the project and check the response in Fiddler. Now the JSON response has correct naming conventions.
