How to use uwp-uri in WPF app？

Question

My WPF app needs notification of win10 style , so I used Microsoft.Toolkit.Uwp.Notifications --NuGet package. But the picture of AppLogoOverride cannot be replaced ，because the schema of AppLogoOverride Uri only 3 types( http:// ms-appx:///
ms-appdata:///) can be used. How to use uwp-uri in WPF app? Or how to replace the picture of AppLogoOverride in another way?
Excuse me ,I’m not good at English .

Answer 1

I created Wpf Application (.Net Core 3.1) and downloaded and installed the package Microsoft.Toolkit.Uwp.Notifications.Then I use the following code to display the Notification with picture. You could refer to the following code.
The code of xaml:

<Grid>  
        <Button Click="Button_Click" Width="100" Height="80">click</Button>  
</Grid>  

The code of xaml.cs(Button):

  private void Button_Click(object sender, RoutedEventArgs e)  
        {  
          new ToastContentBuilder().AddArgument("action", "viewConversation")  
    .AddArgument("conversationId", 9813)  
    .AddText("Ev2 Compiler Library")  
    .AddText("Allow sending build Data to Microsoft")  
    .AddAppLogoOverride(new Uri(@"C:\Users\userName\Desktop\3.jpg"), ToastGenericAppLogoCrop.Default)  
    .Show();  
        }  

The result is shown in the picture:
