I'm reading this [guide](http://www.windowsazure.com/en-us/develop/net/how-to-guides/table-services/#create-table) for how to use Azure table for data storage. But in this guide doesn't really tell you in which folder you should save the files. So I wonder if there's some up to date guide which tells you that, or if someone could show or explain which folder the codes goes into?

For example should I store this code into the model folder?

```
public class CustomerEntity : TableServiceEntity
{
    public CustomerEntity(string lastName, string firstName)
    {
        this.PartitionKey = lastName;
        this.RowKey = firstName;
    }

    public CustomerEntity() { }

    public string Email { get; set; }

    public string PhoneNumber { get; set; }
}

```
