EntityType 'MyProfile' has no key defined. Define the key for this EntityType

Question

I am not sure why I am getting this error message. I have a primary key defined in my sql database for it. Here is my code:

[HttpPost]
    public ActionResult          


        

Answer 1

I ran into this issue also and wanted to add that in Entity Framework version 6 this error occurs because the DbgGeography type has been moved from the assembly system.data.entity and into the entityframework.dll

to resolve this in EF 6+ remove the reference to the entity dll and change the using statement to using System.Data.Entity.Spatial
