如何在 Visual Studio 2015 中修复 DNX/DNVM? [英] How to fix DNX/DNVM in Visual Studio 2015?

问题描述

今天我在 Windows 7 x64 上安装了 VS 2015.主要是为了测试新的 .Net Core 功能等.为了测试，我创建了新的 C#控制台应用程序(包)"解决方案并收到了这条消息:

Today I installed VS 2015 on Windows 7 x64. Mainly to test new .Net Core features and etc. And for test I created new C# "Console Application (Package)" solution and got this message:

DNX SDK 版本dnx-clr-win-x86.1.0.0-beta5"安装失败.该解决方案将在此会话中使用 DNX SDK 版本dnx-clr-win-x86.1.0.0-beta5".

DNX SDK version 'dnx-clr-win-x86.1.0.0-beta5' failed to install. The solution will use DNX SDK version ‘dnx-clr-win-x86.1.0.0-beta5’ for this session.

我无法编译和调试项目.另外，当我在项目属性中打开调试选项卡时，VS 崩溃了.

I can't compile and debug project. Also, when I have opened debug tab in project properties then VS crashed.

打开解决方案时的DNVM输出:

DNVM output when I opened solution:

tion, script file, or operable program. Check the spelling of the name, or if a

有什么解决办法吗?

另外，我之前分别安装了 VS 2015 Preview 和 DNX/DNVM.但我认为，我在 VS 2015 安装之前完全删除了它.这会以某种方式影响当前的 VS 安装吗?

Also, I have previously installed VS 2015 Preview and DNX/DNVM separately. But I think, I completely removed it before VS 2015 installation. Could this somehow affects current VS installation?

推荐答案

这是一个已知问题.

ASP.NET 5:在 Windows 7 SP1 上，没有 DNX SDK 无法安装Powershell 3.0.
