.NET Coding Challenge

This coding challenge is for a .NET developer. We are making the assumption that you are familiar with .NET Core, MVC and REST.

Your task is to build an API that manages users using the scaffolded controller which has already been provided.

There is no strict time limit and you won't be judged on how long it took you to complete, however we would like you to spend no more than 2 hours on this.

1. You must use .NET Core and C#
2. The API should be a ASP.NET Core Web API project
3. The API should consume and return data as JSON
4. You do not need to consider any security implications. This includes using HTTPS or attempting to provide any Authorization/Authentication
5. You do not need any persistent storage. Please use the in-memory cache which has been provided
6. You can use any NuGet package but be prepared to justify its usage

Specification

We want you to develop an API that exposes one RESTful endpoint. This endpoint should provide standard CRUD functionality for Users.

Users

URL Formats

POST

/api/users

GET

/api/users
/api/users/{id}

DELETE

/api/users/{id}

PUT

/api/users/{id}

Fields

Field Name	Data Type	Required	Validation
FirstName	string	true	max length 128
LastName	string	false	max length 128
Email	string	true	must validate to a typical email address
DateOfBirth	DateTime	true	must validate to a valid date

• Every user must have a unique email address
• The user when created must be 18 years or older at the time of the request
• When returning one user or a list of users return back the age of the user in addition to the date of birth

How we will assess your work

We are looking production quality code which utilises design patterns where appropriate and conforms to best practices and principles such as SOLID, etc. Other things we will take into consideration:

• Code should be testable
• We expect you to be mindful of correct HTTP status code usage

You should clone this repository and when you're ready to share your work push it to private repository and our recruitment team will let you know the username to add as a collaborator so we can check it out.
