Windows演示基础（WPF）项目不支持（元素名称）。
大家好，
我有一个大型WPF项目，项目中的每个自定义控件都有许多独立的资源文件。直到几周前，当我尝试在Blend中打开应用程序时，一切都很好。当我尝试打开任何.XAML文件时，我收到每个元素的错误
说：在Windows演示文稿基础中不支持：b
（元素名称） （WPF）项目。
这是针对整个项目中的每个WPF元素。我不知道在Blend开头之间发生了很多工作后发生了什么变化。
我们在Any CPU解决方案平台上使用.NET 4解决方案配置。
有没有人经历过这个？有人有解决方案吗？

谢谢大家。我期待着您的回复。

Hi all,
I have a large WPF project with many separated resource files for each custom control in the project. All was fine until a couple of weeks ago when I tried to open up the application in Blend. When I try to open any .XAML file I get an error for each element
saying:
(Element Name) is not supported in a windows presentation foundation (WPF) project.
This is for every single WPF element throughout the entire project. I don’t know what was changed as a lot of work happened in between openings in Blend.
We are using a .NET 4 solution in the Any CPU Solution Platform configuration.
Has anyone experienced this before? Has anyone got a solution?
Thanks people. I look forward to hearing back from you.

嗨亚当，
关于打开Blend（4？）中的Visual Studio解决方案似乎是一个问题。我进行了测试，没有样品很难找到原因。您能否分享一个可以重现此问题的示例？
It seems that an issue about opening a Visual Studio solution in the Blend (4 ?) . I performed a test, it is hard to find the cause without a sample. Could you please share a sample that can reproduce this issue?
顺便说一下，Windows演示基础（WPF）中不支持" （元素名称） 。项目强> "看来你没有为这个XAMl文件添加XML命名空间，请确保XAMl文件中有以下两个namespce：
By the way, "(Element Name) is not supported in a windows presentation foundation (WPF) project." It seems you do not add the XML namespace for this XAMl file, please ensure below two namespce in the XAMl file:
