如何在 Visual Studio 中使用 XAML 2009 作为设计数据？

我有一个 xaml 文件，我想将其用作 DesignData（具有设计时可创建类型）。我还想在其中使用 XAML 2009 功能，但是 Visual Studio 似乎不接受它，抱怨我想要使用的属性在目标命名空间中不存在。

这是我的 xaml 文件的样子：

<my:ViewModel 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:scg="clr-namespace:System.Collections.Generic;assembly=mscorlib"
    xmlns:my="clr-namespace:MyCompany"
>
    <my:ViewModel.ViewCollection>
        <!-- That part does not work, because it tells me that FactoryMethod and Arguments could not be found in the namespace for prefix 'x'. -->
        <my:BusinessObjectView x:FactoryMethod="my:BusinessObjectView.Convert">
            <x:Arguments>
                <my:BusinessObject />
            </x:Arguments>
        </my:BusinessObjectView>
    </my:ViewModel.ViewCollection>
    <my:ViewModel.BoCollection>
        <!-- Even though the x:TypeArguments syntax for defining objects only appears in XAML 2009, that part works fine - probably because the TypeArguments attribute already existed in that namespace. -->
        <scg:List x:TypeArguments="my:BusinessObject">
            <my:BusinessObject />
        </scg:List>
    </vm:ViewModel.BoCollection>
</my:ViewModel>

这是 XML 项目文件中描述构建操作的片段：

<DesignDataWithDesignTimeCreatableTypes Include="Path/To/File.xaml">
  <SubType>Designer</SubType>
  <Generator>MSBuild:Compile</Generator>
</DesignDataWithDesignTimeCreatableTypes>

那么，问题是什么？是命名空间前缀吗？（在这种情况下，我应该为 XAML 2009 使用哪一个？）这是构建操作吗？我的整个方法有缺陷吗？

原文

I have a xaml file which I want to use as DesignData (with design-time creatable types).
I also want to use XAML 2009 features in it, however Visual Studio does not seem to accept it, complaining that the attributes I want to use do not exist in the target namespace.

Here is what my xaml file looks like:

<my:ViewModel 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:scg="clr-namespace:System.Collections.Generic;assembly=mscorlib"
    xmlns:my="clr-namespace:MyCompany"
>
    <my:ViewModel.ViewCollection>
        <!-- That part does not work, because it tells me that FactoryMethod and Arguments could not be found in the namespace for prefix 'x'. -->
        <my:BusinessObjectView x:FactoryMethod="my:BusinessObjectView.Convert">
            <x:Arguments>
                <my:BusinessObject />
            </x:Arguments>
        </my:BusinessObjectView>
    </my:ViewModel.ViewCollection>
    <my:ViewModel.BoCollection>
        <!-- Even though the x:TypeArguments syntax for defining objects only appears in XAML 2009, that part works fine - probably because the TypeArguments attribute already existed in that namespace. -->
        <scg:List x:TypeArguments="my:BusinessObject">
            <my:BusinessObject />
        </scg:List>
    </vm:ViewModel.BoCollection>
</my:ViewModel>

And here is the fragment in the XML project file that describes the build action:

<DesignDataWithDesignTimeCreatableTypes Include="Path/To/File.xaml">
  <SubType>Designer</SubType>
  <Generator>MSBuild:Compile</Generator>
</DesignDataWithDesignTimeCreatableTypes>

So, what is the problem?
Is it the namespace prefix? (In which case, which one should I use for XAML 2009?)
Is it the build action?
Is my whole approach flawed?

“松散 XAML 文件”是一个与 XAML 2009 的概念正交的概念。
松散 XAML 文件是在运行时加载的纯 XAML（无代码隐藏）文件。 http://wpf.2000things.com/2010/10/ 20/100-松散-xaml-文件/
XAML 2009 是 XAML 语言的一个版本和一组相应的架构。

要使 .xaml 文件“松散”，您只需停止编译它（在文件属性中）。
要加载松散的 .xaml 文件，您需要使用 XamlReader.Load 方法 http://msdn.microsoft.com/en-us/library/system.windows.markup.xamlreader.load.aspx http://www.c-sharpcorner .com/uploadfile/37db1d/understanding-uncompiled-xaml-to-design-dynamic-ui-in-wpf/
奇怪的是，XAML2009 文件似乎仍然使用 2006 架构。
