C# XML命名空间中不存在该标记

我在“FluidMoveBehavior”上看到以下错误

The tag 'FluidMoveBehavior' does not exist in XML namespace
'http://schemas.microsoft.com/expression/2010/interactions'.
Line 22 Position 14.

将程序集

microsoft.expression.interactions.dll

添加到项目引用中

可在此免费获取：

此处的EULA和重新分配：

C:\ProgramFiles（x86）\Microsoft SDK\Expression\Blend\.NETFramework\v4.0

对我来说正在工作

我做了以下步骤

1） 项目>属性>目标框架>4.0

2） 重新制作“System.Windows.Interactivity”的参考

我希望它对您有用。

它可能会解决您的问题，嗯，我已经尝试过了，但没有任何用处：（Try

xmlns:ei=“clr namespace:Microsoft.Expression.Interactivity.Layout；assembly=Microsoft.Expression.Interactions”

谢谢，但仍然有相同的错误消息~你到底安装了Expression Blend吗？microsoft.Expression.interactions.dll已经在我的项目引用中：）啊，你的问题还不清楚。它应该有效（我有一个有效的例子）。程序集microsoft.expression.interactions.dll的版本是什么？该错误表示您拥有的任何版本都不包含FluidMoveBehavior。在对象浏览器中打开它，如果在其中看到FluidMoveBehavior，请告诉我。您可能有一个不包含此类的旧版本。我已打开对象浏览器，FluidMoveBehavior位于Microsoft.Expression.Interactivity.Layout下。我的Microsoft.Expression.interactions.dll的版本为3.5.0.0
