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

For anyone coming to this in the future, the OData v4 team have fixed this issue.

[Column(TypeName = "date")]
public DateTime Birthday { get; set; }

This will now auto-resolve to Edm.Date.

If you are like me and are doing date type by convention, you have to manually declare the properties as dates lest they be auto-resolved as DateTimeOffset. OData currently does not allow you to add your own conventions.

customer.Property(c => c.Birthday).AsDate();
