아래처럼 EmailValidationBehavior 를 이용하면 Email 유효성을 검사할수 있습니다.

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage
    x:Class="Maui.ToolKitMaui.MainPage"
    xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    xmlns:animations="clr-namespace:Maui.ToolKitMaui.Animations"
    xmlns:mct="http://schemas.microsoft.com/dotnet/2022/maui/toolkit">

    <ScrollView>
        <VerticalStackLayout
            Padding="30,0"
            Spacing="15"
            VerticalOptions="Center">

            <!--  EmailValidationBehavior  -->
            <Entry
                HorizontalOptions="FillAndExpand"
                Placeholder="Input Email"
                VerticalOptions="Center">
                <Entry.Behaviors>
                    <mct:EmailValidationBehavior
                        x:Name="EmailValidator"
                        DecorationFlags="Trim"
                        Flags="ValidateOnValueChanged"
                        InvalidStyle="{StaticResource InvalidEntryStyle}"
                        ValidStyle="{StaticResource ValidEntryStyle}" />
                </Entry.Behaviors>
            </Entry>
            <Label
                FontSize="15"
                HorizontalOptions="Start"
                HorizontalTextAlignment="Start"
                IsVisible="{Binding IsNotValid, Source={x:Reference EmailValidator}}"
                Text="Invalid Email"
                TextColor="Red"
                VerticalOptions="Start"
                VerticalTextAlignment="Start" />
        </VerticalStackLayout>
    </ScrollView>

</ContentPage>

Email 형식에 에 부합한지 여부를 IsNotValid 필드를 확인해 표시할수 있습니다.

실행결과
