wpf VisualState与wpfToolkit冲突? [英] wpf VisualState conflicts with wpfToolkit?

问题描述

我正在使用wpfToolkit 3.5作为参考程序集在VS2010中构建应用程序.

I am building an application in VS2010 with wpfToolkit 3.5 as referenced assembly.

我试图从ExpressionBlend 4中添加一些VisualState，但是在尝试构建项目时出现以下错误.

I tried to add some VisualStates from ExpressionBlend 4 and I am getting the following error when I am trying to build the project.

类型'System.Windows.VisualState' 在两个'c:\ Program文件中都存在 (x86)\参考 程序集\ Microsoft \ Framework.NETFramework \ v4.0 \ PresentationFramework.dll' 和'c:\ Program Files(x86)\ WPF 工具包\ v3.5.50211.1 \ WPFToolkit.dll'

The type 'System.Windows.VisualState' exists in both 'c:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.0\PresentationFramework.dll' and 'c:\Program Files (x86)\WPF Toolkit\v3.5.50211.1\WPFToolkit.dll'

这是代码

<VisualStateManager.VisualStateGroups>
        <VisualStateGroup x:Name="ShowHideRoomNumber">
            <VisualState x:Name="Show"/>
            <VisualState x:Name="Hide">
                <Storyboard>
                    <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)" Storyboard.TargetName="comboBox">
                        <DiscreteObjectKeyFrame KeyTime="0" Value="{x:Static Visibility.Hidden}"/>
                    </ObjectAnimationUsingKeyFrames>
                </Storyboard>
            </VisualState>
        </VisualStateGroup>
    </VisualStateManager.VisualStateGroups>

我也尝试过，但是发生了相同的错误

I tried also and this but the same error occured

xmlns:vsm="clr-namespace:System.Windows;assembly=WPFToolkit"

<vsm:VisualStateManager.VisualStateGroups>
        <vsm:VisualStateGroup x:Name="ShowHideRoomNumber">
            <vsm:VisualState x:Name="Show"/>
            <vsm:VisualState x:Name="Hide">
                <Storyboard>
                    <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Visibility)" Storyboard.TargetName="comboBox">
                        <DiscreteObjectKeyFrame KeyTime="0" Value="{x:Static Visibility.Hidden}"/>
                    </ObjectAnimationUsingKeyFrames>
                </Storyboard>
            </vsm:VisualState>
        </vsm:VisualStateGroup>
    </vsm:VisualStateManager.VisualStateGroups>

有什么建议吗?

谢谢

这是 extern别名的用途 http://msdn.microsoft.com/en-us/library/ms173212.aspx

您可以通过

1. 右键单击WPFToolkit参考以查看其属性，
2. 将别名"字段更改为您喜欢的任何内容.
