在ValidationMessage使用For可以直接放lambda表達式

<EditForm>
    <p>
        <label for="productionDate">Production Date: </label>
        <InputDate id="productionDate" @bind-Value="starship.ProductionDate" />
        <ValidationMessage For="() => starship.ProductionDate" />
    </p>
    <button type="submit">Submit</button>
</EditForm>
