VS2015 C＃交互式：错误CS7069：对类型“对象”的引用声称它在“ System.Runtime”中定义，但找不到 [英] VS2015 C# interactive: error CS7069: Reference to type 'Object' claims it is defined in 'System.Runtime', but it could not be found

问题描述

我刚刚更新为 VS2015 Update 2 ，并开始使用 C＃交互式窗口。我想在.NET 4.0目标库项目之一的静态类中使用静态方法，因此我在解决方案资源管理器中右键单击该项目，然后选择 Initialize Interactive with Project 。交互式窗口中的输出看起来像这样（为简便起见，我用 ..替换了一些完整路径）：

I just updated to VS2015 Update 2, and started playing around with the C# interactive window. I wanted to use a static method in a static class in one of my .NET 4.0 targeted library projects, so I right-clicked on the project in Solution Explorer, and selected Initialize Interactive with Project. The output in the interactive window looks like this (I replaced some of the full paths with '..' for brevity):

#reset

请注意结尾处讨厌的小线条，阻碍了我通往幸福的道路：

Note the nasty little line at the end, blocking my path to happiness:

（1 ，7）：错误CS7069：对类型对象的引用声称它是在 System.Runtime中定义的，但找不到它

I获取项目中的类的智能感知，但是每次尝试运行语句时，都会遇到相同的错误。我仍然可以运行以下简单的内容：

I get intellisense for the classes in the project, but I get the same error any time I try to run a statement. I can still run simple things like:

> string.Format("No one knows my {0}", "suffering")
"No one knows my suffering"
>

任何人都知道为什么会发生或如何解决？我将使用任何[未]成功的建议修复程序来更新此问题。

Anyone have any ideas about why this is happening or how to fix it? I'll update this question with any [un]successful suggested fixes.

推荐答案

最终为我解决的问题是输入此 中的右键。 C＃交互式窗口。：

What ultimately fixed it for me was entering this right in the C# Interactive window.:

#r System.Runtime

如果有人可以提供全面的背景说明以了解其工作原理，我很乐意为您提供可接受的答案。我只是很幸运。

If there's anyone that can provide a thorough background explanation as to why this worked, I'd love to give you the accepted answer. I just got lucky.
