Regarding removing column in database RRS feed

  • Question

  • Currently I created the database first, then I use the entity framework 4.1 to access the database.

    The example is like this:

    The database has one table named users has two column,they are password and ConfirmedPassword.

    And in my application I use the following code.

    public class user


    public string password





    public string ConfirmedPassword



    I find that if I delete the ConfirmedPassword in database and in user,

    when I create new user and call db.SaveChanges(), it still show that the ConfirmedPassword and Discriminator is invalid.

  • Hi Tony,

    I guess you may use DbContext Generation Item, right?  If in this case, you should open your edmx and delete the property on desinger, when you save edmx file, there is a alert for reloading your entities.

    Have a nice day.
