You are about to create a Web API that provides support to allow logging incomes of

clients. The API allow adding, removing, editing and querying user incomes. No client$-$

side implementation is required for this implementation.

Project Creation $(10\%)$

$$ Create an ASP.Net Core Web API Application project.

$$ Name it $($YourFirstName$\_$YourLastName$)$

$$ Delete WeatherForecastController and WeatherForecast class

$$ Add a new api controller and call it IncomesController

$$ Create Models folder then create Income class as following:

public class Income

$\{$

public int Id $\{$ get; set; $\}$

public string Description $\{$ get; set; $\}$

public double Amount $\{$ get; set; $\}$

public bool IsReceived $\{$ get; set; $\}$

public int UserId $\{$ get; set; $\}$

$\}$

Make your first commit with a message that includes your name, the time in your

machine, and an appropriate message $($e$.$g$.$ "Aeiman: $12$:$30,$ project initialized$)$

Task $2$: API endpoints: $(80\%)$

Update the IncomesController so it provides the following endpoints.

Notes:

$-$ the numbers given are just examples. The user should specify them as needed.

$-$ You might need to use postman to create some incomes in the database so you

can test the different endpoints.

$-$ You need to place the business logic in a static Repository class. Each endpoint

should call a relevant method in the static repository class to execute the

required tasks.

$1.$ Endpoint GET $/$api$/$incomes$/1$

$$ Return a number that represents the total $($sum$)$ income of the of the user

who has id $=1($userid$=1)$

$2.$ Endpoint GET $/$api$/$incomes$/1/$true

$$ Return a list of all the incomes of the user who has id $=1($userid$=1)$ that

are received $($IsReceived $=$ true$)$

$$ You need to add a custom route to allow receiving three

parameters in the action method.

$[$HttpGet$("\{$userId$\}/\{$isReceived$\}\}")]$

$3.$ Endpoint DELETE $/$api$/$incomes$/1$

$$ Delete the incomes for the user $1($userid $=1)$

$$ If the database doesn$$t have any income that matches the request

then the api should return a $404$ error.

$4.$ POST $/$api$/$incomes

$$ Create a new income entry in the database

$$ The new Income is supposed to be received in json format

$$ The description and the amount are required. If the client doesn$$t

provide them, then the API should return an error.

$$ Return the new created income to the client.

Make last commit with a message that includes your name, the time in your machine,

and an appropriate message $($e$.$g$.$ "Aeiman: $2$:$30,$ work is done$)$
