ContactService You are being asked to create a simple contact entry system. You should create a REST API that will enable a client to perform CRUD operations on the contact collection.
REQUIREMENTS

1. Create a new REST API using .NET technologies with the following endpoints: HTTP Method Route Description GET /contacts List all contacts POST /contacts Create a new contact PUT /contacts/{id} Update a contact GET /contacts/{id} Get a specific contact DELETE /contacts/{id} Delete a contact

2. The contact entry request when creating or updating a contact will be JSON and have the following format: Format Example

{ "name": { "first": string, "middle": string, "last": string }, "address": { "street": string, "city": string, "state": string, "zip": string }, "phone": [ { "number": string, "type": string ["home" | "work" | "mobile"] } ], "email": string }

{ "name": { "first": "Harold", "middle": "Francis", "last": "Gilkey }, "address": { "street": "8360 High Autumn Row", "city": "Cannon", "state": "Delaware", "zip": "19797" }, "phone": [ { "number": "302-611-9148", "type": "home" }, { "number": "302-532-9427", "type": "mobile" } ], "email": "harold.gilkey@yahoo.com" }

3. Contact entries returned to the client by the API will be JSON and have the following format: Format Example

{ "id": number, "name": { "first": string, "middle": string, "last": string }, "address": { "street": string, "city": string, "state": string, "zip": string }, "phone": [ { "number": string, "type": string ["home" | "work" | "mobile"] } ], "email": string }

{ "id": 101, "name": { "first": "Harold", "middle": "Francis", "last": "Gilkey }, "address": { "street": "8360 High Autumn Row", "city": "Cannon", "state": "Delaware", "zip": "19797" }, "phone": [ { "number": "302-611-9148", "type": "home" }, { "number": "302-532-9427", "type": "mobile" } ], "email": "harold.gilkey@yahoo.com" }

4. Provide a storage mechanism for storing the contact entries. If you use a database you do not need to include the database, but you should include instructions to set up and create the database. In order to simplify the overall solution and minimize runtime dependencies, you are strongly encouraged to use an embedded database such as LiteDB or something similar.

5. Write unit tests to verify functionality where you deem it appropriate.

6. Upload all files and instructions for building the project (if necessary) to GitHub and provide a link to us for review.
