먼저

FetchData.razor 에서

<EditForm Model="_addForecast" OnInvalidSubmit="SaveForecast">

    @* Form Validation 기능 ON*@
    <DataAnnotationsValidator />
    @* 에러가 있으면 메시지 상세 출력*@
    <ValidationSummary />

    <label for="TemperatureC">TemperatureC</label>
    <InputNumber class="form-control" placeholder="TemperatureC" @bind-Value="_addForecast.TemperatureC" />
    <label for="Summary">Summary</label>
    <InputText class="form-control" placeholder="Summary" @bind-Value="_addForecast.Summary" />
    <br />
    <button class="btn btn-primary" type="submit">Save</button>
</EditForm>

WeatherForecast에서

    public class WeatherForecast
    {
        public DateTime Date { get; set; }

        [Required(ErrorMessage = "Need TemperatureC!")]
        [Range(typeof(int),"-100","100")]
        public int TemperatureC { get; set; }

        public int TemperatureF => 32 + (int)(TemperatureC / 0.5556);

        [Required(ErrorMessage = "Need Summary!")]
        [StringLength(10, MinimumLength = 2, ErrorMessage = "2~10")]
        public string Summary { get; set; }
    }

이렇게 해주었는데

Need Summary가 뜨지 않는데 이유를 알수 있을까요?
