ASP.NET Core 6 MVC

我在显示模型的验证消息时遇到问题。

在下面的代码中， asp-validation-summary="All" 正确显示所有消息，而 asp-validation-summary="ModelOnly" 不显示任何内容。我在呈现的 HTML 代码中注意到的一个问题是 span class="field-validation-valid" 的类名，而它应该是 class="field-validation-error"。我不明白为什么，以前有人遇到过这个问题吗？

  <div asp-validation-summary="All" class="text-danger"></div>
    <div class="card col-xxl-6 col-xl-6 col-lg-6 col-md-6 col-sm-12 col-xs-12 offset-xxl-3 offset-xl-3 offset-lg-3 offset-md-3">
        <div class="card-header">
            <p class="card-title fs-4">Veuillez saisir les données du compte</p>
        </div>
        <div class="card-body">
            <form method="post" asp-controller="user" asp-action="create">
                <div asp-validation-summary="ModelOnly" class="text-danger"></div>
                <div class="row align-items-center mb-3">
                    <div class="input-group">
                        <span class="input-group-text">Prénom</span>
                        @*@Html.EditorFor(m => m.FirstName, new { htmlAttributes = new { @class = "form-control rounded" } })*@
                        <input asp-for="@Model.FirstName" name="model.FirstName" aria-describedby="userCreate" type="text" class="form-control rounded" />
                        <span asp-validation-for="@Model.FirstName" class="text-danger"></span>
                    </div>
                </div>

呈现的 HTML
