@ Html.ValidationMessageFor未显示错误消息

Question

我的应用程序下面有以下appsettings值。出于某种原因， @ Html.ValidationMessageFor 不会在服务器端显示错误消息。当我将密钥 ClientValidationEnabled 值更改为 false 时，它正常工作。我正在使用Fluent为我们下面的模型属性进行自定义验证

   <add key="ClientValidationEnabled" value="true" /> 
   <add key="UnobtrusiveJavaScriptEnabled" value="true" />

   @Html.TextBoxFor(model => model.AccountSetupView.SecurityAnswer, new { @class = "customText mandatory", @title = @Html.Translate("Answer", ResourceAreas.Onboarding.AccountSetupSecurityAnswerLabel), placeholder = @Html.Translate("Answer", ResourceAreas.Onboarding.AccountSetupTextBoxSecurityAnswerPlaceholderValue), maxlength = "40" })
   @Html.ValidationMessageFor(m => m.AccountSetupView.SecurityAnswer)

流利规则

 RuleFor(x => x.SecurityAnswer).ValidEmail().
 WithLocalizedMessage(ResourceAreas.Messages.Message_Onboarding_100007_numbersonly);
