问题描述

我已经为 Windows 通用平台(Win 10 UWP)创建了一个类库.

该库包含一些用户控件.

当我将此库中的 dll 添加到 Win 10 UWP 应用程序并使用 UserControls 时，它会给出 XamlParseException，如

我们需要参考的文件:

• ClassLibrary1(类库名称)文件夹
  • ClassLibrary1.xr.xml
  • CustomPopupControl.xaml
• ClassLibrary1.dll
• ClassLibrary1.pri -> 包资源索引文件

将这些文件复制到任何地方，UWP项目只需在Visual Studio中添加对ClassLibrary1.dll文件的引用，它们都会自动添加.

当我尝试在InitializeComponent()"方法上使用 UserControl 时，它只会引发 xaml 解析异常

添加引用时可能缺少 .pri 文件.

I have created a class library for Windows Universal Platform (Win 10 UWP).

The library houses some UserControls.

When I add the dll from this library to a Win 10 UWP app, and use the UserControls, it gives a XamlParseException as stated here in another question I posted

But when I reference the whole project, there is no exception and I can use the UserControl. This happens supposedly because there are xbf files which are not added to the Win 10 app project when I just reference the dll file.

In a certain project, I need to add the xbf files manually to the Win 10 app project, I cannot reference the whole project, I can only reference the dll and add the required files.

I tried creating a folder in Visual Studio project and adding the xbf files, and also tried creating folders with different names and copying the xbf files there in the "bin" directory through windows explorer. But no success.

So, how do I manuall add xbf files to a Windows 10 UWP project?

Update 1 :- XAML & Code for reference

public sealed partial class CustomPopupControl : UserControl
{
    internal CustomPopupControl()
    {
        this.InitializeComponent();    //-------CRASHES HERE-------
    }

    internal CustomPopupControl() : base()
    {
        Debug.WriteLine("CustomPopupControl");
        //
        //do some stuff
        //
        //
    }

    private void OnPopupLoaded(object sender, RoutedEventArgs e)
    {
        this.Popup_Container.HorizontalOffset = (Window.Current.Bounds.Width - Grid_Child.ActualWidth) / 2;
        this.Popup_Container.VerticalOffset = (Window.Current.Bounds.Height - Grid_Child.ActualHeight) / 2;
    }

    internal void OpenPopup()
    {
        Debug.WriteLine("OpenPopup");
        Popup_Container.IsOpen = true;

        var currentFrame = Window.Current.Content as Frame;
        var currentPage = currentFrame.Content as Page;
        currentPage.IsHitTestVisible = false;

        Debug.WriteLine("OpenPopup Done");
    }

    private void OnLayoutUpdated(object sender, object e)
    {
        if (Grid_Child.ActualWidth == 0 && Grid_Child.ActualHeight == 0)
        {
            return;
        }

        double ActualHorizontalOffset = Popup_Container.HorizontalOffset;
        double ActualVerticalOffset = Popup_Container.VerticalOffset;

        double NewHorizontalOffset = (Window.Current.Bounds.Width - Grid_Child.ActualWidth) / 2;
        double NewVerticalOffset = (Window.Current.Bounds.Height - Grid_Child.ActualHeight) / 2;

        if (ActualHorizontalOffset != NewHorizontalOffset || ActualVerticalOffset != NewVerticalOffset)
        {
            Popup_Container.HorizontalOffset = NewHorizontalOffset;
            Popup_Container.VerticalOffset = NewVerticalOffset;
        }
    }
}

XAML :-

<UserControl
x:Class="MyLibrary.CustomPopupControl"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:MyLibrary"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d"
d:DesignHeight="300"
d:DesignWidth="400">

<Popup Name="Popup_Container" LayoutUpdated="OnLayoutUpdated">
    <Border BorderThickness="1" BorderBrush="{ThemeResource AppBarBorderThemeBrush}">
        <Grid Name="Grid_Child">
            <Grid Name="Grid_Content"  Height="300" Width="400" />
        </Grid>
    </Border>
</Popup>

I use the control directly in another app, as -

CustomPopupControl myctrl = new CustomPopupControl();
myctrl.OpenPopup();

In addition to Thomas's answer, you need to check the "Generate library layout" option in the Build configuration under the project's Properties page.

The files we need to reference:

• ClassLibrary1(Class Library name) Folder
  • ClassLibrary1.xr.xml
  • CustomPopupControl.xaml
• ClassLibrary1.dll
• ClassLibrary1.pri -> Package Resource Index file

Copy these files to anywhere and the UWP project just need to add reference to the ClassLibrary1.dll file in the Visual Studio, all of them will be added automatically.

It just throws a xaml parse exception when I try to use the UserControl on the "InitializeComponent()" method

Perhaps the .pri file is missing when you add the reference.
