在asp.net webforms應用程序中爲用戶數據庫添加字段

Question

我是VS2015的新手，並且已經開始運行了。我的首選是在VB中運行，我有一個示例asp.net web ap打開。隨着新的實體框架，我試圖添加一個字段「PrincipalID」到aspnetusers數據庫。我已啓用遷移並將該字段添加到register.aspx代碼文件。我添加了遷移並運行了更新的數據庫而沒有錯誤，但是新字段沒有顯示在數據庫中。任何人都知道爲什麼？

代碼段register.aspx文件：

Partial Public Class Register 
Inherits Page 
Protected Sub CreateUser_Click(sender As Object, e As EventArgs) 
    Dim userName As String = Email.Text 
    Dim manager = Context.GetOwinContext().GetUserManager(Of ApplicationUserManager)() 
    Dim signInManager = Context.GetOwinContext().Get(Of ApplicationSignInManager)() 
    Dim user = New ApplicationUser() With {.UserName = userName, .Email = userName, .PrincipalID = "test"} 
    Dim result = manager.Create(user, Password.Text) 
    If result.Succeeded Then 
     ' For more information on how to enable account confirmation and password reset please visit http://go.microsoft.com/fwlink/?LinkID=320771 
     ' Dim code = manager.GenerateEmailConfirmationToken(user.Id) 
     ' Dim callbackUrl = IdentityHelper.GetUserConfirmationRedirectUrl(code, user.Id, Request) 
     ' manager.SendEmail(user.Id, "Confirm your account", "Please confirm your account by clicking <a href=""" & callbackUrl & """>here</a>.") 

     signInManager.SignIn(user, isPersistent := False, rememberBrowser := False) 
     IdentityHelper.RedirectToReturnUrl(Request.QueryString("ReturnUrl"), Response) 
    Else 
     ErrorMessage.Text = result.Errors.FirstOrDefault() 
    End If 
End Sub
