New HTMLDocument from text file fails under UWP Release configuration

Aspose.HTML Product Family

Create a Visual Basic UWP project in Visual Studio.
In MainPage.xaml:

<Page
    x:Class="HTML解析测试.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:HTML解析测试"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d">
	<TextBlock x:Name="Value"/>
</Page>

In MainPage.xaml.vb:

' https://go.microsoft.com/fwlink/?LinkId=402352&clcid=0x804 上介绍了“空白页”项模板

''' <summary>
''' 可用于自身或导航至 Frame 内部的空白页。
''' </summary>
Public NotInheritable Class MainPage
    Inherits Page

	Private Async Sub MainPage_Loaded(sender As Object, e As RoutedEventArgs) Handles Me.Loaded
		Dim HtmlDocument As New Aspose.Html.HTMLDocument(Await (Await Windows.Storage.StorageFile.GetFileFromApplicationUriAsync(New Uri("ms-appx:///HTML文档.html"))).OpenStreamForReadAsync, "http://wj.shtc.cn")
		Value.Text = DirectCast(HtmlDocument.GetElementById("__VIEWSTATE"), Aspose.Html.HTMLInputElement).Value
	End Sub
End Class

This code should find the input element with ID “__VIEWSTATE” from the HTML text file and show its value. However, it run successfully only under Debug configuration. Aspose can’t find the element under Release configuration.

Please use synchronous methods to get the desired output as shown below.

Dim HtmlDocument As New Aspose.Html.HTMLDocument((Windows.Storage.StorageFile.GetFileFromApplicationUriAsync(New Uri("ms-appx:///HTML文档.html"))
.GetAwaiter().GetResult()).OpenStreamForReadAsync.GetAwaiter()
.GetResult(), "http://wj.shtc.cn")
