Entity.NET Concept

Summary

A simple experiment prototyping a concept for strongly typed ORMs.

Getting Started

The idea that Entity.NET is attempting to conceptualize is one where strongly-typed objects are used with an ORM system. The primary objective is to use strongly typed identifiers (Keys.Customer) that restricts the usages of an applications ORM. The concept is from the following scenario:

var cust = new Models.Customer() { Name = "John Doe" };
var entity = Repository.Add(cust);
//entity.Key => underlying int (10)
Repository.Update(entity.Key, new Models.Customer() { Name = "David Smith" });

//...

var existing = (Keys.Customer)10;
var updatedCust = Repository.Find(entity.Key);
Console.WriteLine(updatedCust.Name); //David Smith

The code would be generated from the base definition of an entity below. Roslyn would generate the strongly-typed code using Attributes on the models to control the code outputs.

[Entity(typeof(int))]
class Customer {
    public string Name { get; set; }
    public string Address { get; set; }
}
