我运行Aspnet_regsql.exe来创建架构.它创建了带有下划线的表：例如aspnet_Users.它还创建了相关的存储过程.这些存储过程确实有效,并且它们会向表中添加记录：例如,用户被添加到aspnet_Users中.

当我尝试使用Login.aspx时,它在manager.find上崩溃并出现错误：“无效的对象名称’dbo.AspNetUsers’.”

protected void LogIn(object sender,EventArgs e)
    {
        if (IsValid)
        {
            // Validate the user password
            var manager = new UserManager();
            ApplicationUser user = manager.Find(UserName.Text,Password.Text);
            if (user != null)
            {
                IdentityHelper.SignIn(manager,user,RememberMe.Checked);
                IdentityHelper.RedirectToReturnUrl(Request.QueryString["ReturnUrl"],Response);
            }
            else
            {
                FailureText.Text = "Invalid username or password.";
                ErrorMessage.Visible = true;
            }
        }
    }
