在ADO.NET实体框架上，DbContext对象没有表字段

Question

I am using VS 2015 Community, Windows 10, Microsoft SQL 2016 SP1. I added an SQL Server DB to the project. Then I added a table named 'Dict' to that database.

I am following this tutorial (at 20:00) which explains how to use ADO.NET with Visual Studio. The video is a bit outdated, but I followed the same steps to create the entity model. But when I get to the part in 21:01, my DbContext object (seen below) returns an error when I try to access context.Dict. It says no definition found for Dict.

    public partial class _Default : Page
      {
         protected void Page_Load(object sender, EventArgs e)
         {
            var context = new DictServerEntities1();

            var words = context.Dict;

UPDATE:

I imported some sample databases provided by Microsoft (called Northwind), and they work with EF. So my table is somehow not valid for EF, I'm guessing because it does not contain a primary key.

Answer 1

The answer to this was to use a table with a primary key. I was not using a primary key.
