的Visual Studio 2012 - 找不到在.NET 4.5框架System.Transactions的组装 [英] Visual Studio 2012 - Can't find System.Transactions assembly in .NET 4.5 framework

问题描述

我想添加一个引用到System.Transactions的在C＃的Visual Studio 2012的项目，但System.Transactions的不可用的框架组件中，你可以在下面的截图亲眼看到：

I'm trying to add a reference to System.Transactions in a C# Visual Studio 2012 project, but System.Transactions isn't available among the framework assemblies, as you can see for yourselves in the below screenshot:

有谁知道为什么System.Transactions的将是无法给我吗？我怎样才能让它重新出现？

Does anyone know why System.Transactions would be unavailable to me? How can I make it reappear?

编辑： 修正了截图，感谢马克！

Fixed the screenshot, thanks Marc!
