Can not find System.Windows Assembly
提问by
This is the error we get:
这是我们得到的错误：
Error 1 The type 'System.Windows.Point' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Windows, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e'. C:\PacMan\PacMan\PacMan\PacManTests\UnitTest1.cs 65 13 PacManTests
错误 1 在未引用的程序集中定义了类型“System.Windows.Point”。您必须添加对程序集“System.Windows, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e”的引用。C:\PacMan\PacMan\PacMan\PacManTests\UnitTest1.cs 65 13 PacManTests
We get this error in our unit test project which cant find the System.Windows Assembly but our main project can find the assembly and run it fine.
我们在无法找到 System.Windows 程序集的单元测试项目中遇到此错误，但我们的主项目可以找到该程序集并正常运行。
Does anyone have any input or advice on where or how we can reference System.Windows to fix this problem?
有没有人对我们在哪里或如何引用 System.Windows 来解决这个问题有任何意见或建议？

Right click on your "References" folder and click "Add Reference" and then select System.Windows under the .NET tab.
右键单击“引用”文件夹并单击“添加引用”，然后在 .NET 选项卡下选择 System.Windows。

Add the assembly reference as you'd add any other framework assembly reference:
添加程序集引用，就像添加任何其他框架程序集引用一样：
- Right-click on the project
- Select "Add reference"
- Select the .NET tab on the left, and find "System.Windows" in the list of assemblies
- Double-click on "System.Windows" and the assembly reference will be added
- 右键单击项目
- 选择“添加参考”
- 选择左侧的.NET选项卡，在程序集列表中找到“System.Windows”
- 双击“System.Windows”，将添加程序集引用

If you don't have System.Windows in your .NET references, try WindowsBase. That fixed my reference to System.Windows.Point in VS 2008.
如果您的 .NET 引用中没有 System.Windows，请尝试 WindowsBase。这修复了我在 VS 2008 中对 System.Windows.Point 的引用。

You'll also run into this error if you use the Portable Library Toolsas it's not supported.
如果您使用不支持的便携式库工具，您也会遇到此错误。

In my case there was no System.Windows reference available to pick up.
I had to include a reference to WindowsBase
就我而言，没有可供选择的 System.Windows 参考。
我必须包含对WindowsBase的引用

I had the same problem, however it was caused because we are using a Portable Class library and only occurred on certain PC installations.
我遇到了同样的问题，但是这是因为我们使用的是可移植类库，并且只发生在某些 PC 安装上。
I found the issue to be fixed on these installation with:
我发现问题可以通过以下安装解决：
http://www.microsoft.com/en-us/download/details.aspx?id=3556
http://www.microsoft.com/en-us/download/details.aspx?id=3556
As this fix is included with VS2010 and Windows Update it would only occur on certain PCs.
由于此修复程序包含在 VS2010 和 Windows 更新中，因此它只会出现在某些 PC 上。
