Handling Dates with OData v4, EF6 and Web API v2.2

Question

I\'m in the midst of upgrading from v1-3 to v4, but I\'ve run into a few problems.

My understanding is that DateTime is unsupported, and I have to always use DateTim

Answer 1

One option is to define a new property in the entity. Say Title is mapped to EF:

public partial class Title
{
    public int Id { get; set; }
    public string Name { get; set; }
    public Nullable CreatedOn { get; set; }
}

then add a new property of DateTimeOffset:

public partial class Title
{
    [NotMapped]
    public DateTimeOffset? EdmCreatedOn
    {
        // Assume the CreateOn property stores UTC time.
        get
        {
            return CreatedOn.HasValue ? new DateTimeOffset(CreatedOn.Value, TimeSpan.FromHours(0)) : (DateTimeOffset?)null;
        }
        set
        {
            CreatedOn = value.HasValue ? value.Value.UtcDateTime : (DateTime?)null;
        }
    }
}

and the code for generate OData Model looks like:

    public static IEdmModel GetModel()
    {
        ODataConventionModelBuilder builder = new ODataConventionModelBuilder();
        EntityTypeConfiguration
