How to customize the border for tab header area in .NET MAUI Tab View?

This article explains how to customize the border for the tab header area in .NET MAUI Tab View. You can achieve this by using the following built-in properties of the SfTabView:

• TabBarBorderColor - sets the border color
• TabBarBorderThickness - sets the border thickness
• TabBarCornerRadius - sets the corner radius of the tab bar’s border

MainPage.Xaml

<tabView:SfTabView TabBarBorderColor="#2196F3" TabBarBorderThickness="3" TabBarCornerRadius="24"
                   IndicatorBackground="#E3F2FD" IndicatorPlacement="Fill" 
                   TabBarPlacement="Bottom">
   <tabView:TabItemCollection>
       <tabView:SfTabItem Header="Library">
           <Label Text="Library Content" HorizontalOptions="Center" VerticalOptions="Center"/>
       </tabView:SfTabItem>
       <tabView:SfTabItem Header="Browse">
           <Label Text="Browse Content" HorizontalOptions="Center" VerticalOptions="Center"/>
       </tabView:SfTabItem>
       <tabView:SfTabItem Header="Playlists">
           <Label Text="Playlist Content" HorizontalOptions="Center" VerticalOptions="Center"/>
       </tabView:SfTabItem>
   </tabView:TabItemCollection>
</tabView:SfTabView>

MainPage.Xaml.cs

SfTabView tabView = new SfTabView
{
   TabBarBorderColor = Color.FromArgb("#2196F3"),
   TabBarBorderThickness = 3,
   TabBarCornerRadius = 24,
   IndicatorBackground = Color.FromArgb("#E3F2FD"),
