Relationship between entities

[gaui]

When I'm setting up the entities I use these pseudo _X_value attributes to reference other entities.

Isn't that possible to create relationship between entities?

For example:

var productId = Guid.NewGuid();
var product = new Entity
{
    Id = productId,
    LogicalName = "product"
};

var carId = Guid.NewGuid();
var car = new Entity
{
    Id = carId,
    LogicalName = "car",
    Attributes =
    {
        ["_productid_value"] = productId
    }
};

Or do I have to do:

var productId = Guid.NewGuid();
var product = new Entity
{
    Id = productId,
    LogicalName = "product"
};

var carId = Guid.NewGuid();
var car = new Entity
{
    Id = carId,
    LogicalName = "car",
    Attributes =
    {
        ["productid"] = product.ToEntityReference()
    }
};

You could just do:

var car = new Entity("car")
{
    Id = carId,
    ["productid"] = product.ToEntityReference()
};

Although better if you could use early bound.
