.NET Core - 框架“DNXCore,Version=v5.0"的参考程序集；没有找到 [英] .NET Core - The reference assemblies for framework "DNXCore,Version=v5.0" were not found

问题描述

将 .NET 核心库 (DNXCore50) 从 VS 2015 迁移到 VS 2017 时出现此错误.

I'm getting this error when migrating a .NET core lib (DNXCore50) from VS 2015 to VS 2017.

未找到框架DNXCore,Version=v5.0"的参考程序集.

The reference assemblies for framework "DNXCore,Version=v5.0" were not found.

我的项目文件目前看起来像这样:(在 VS 2017 迁移向导将我的project.json"迁移到 .csproj 文件之后)

My project file currently looks like this: (after the VS 2017 migration wizard migrated my "project.json" to a .csproj file)

我在编译时遇到上述错误.我尝试过的事情:

I'm getting the above mentioned error when I compile. Things I've tried:

• 改用 .NETPortable v5.0.这里缺少的课程太多.
• 改用 .NETCoreApp v1.0.每节课都不见了.我是否使用了错误的版本?
• 使用 DNXCore.没有缺课.VS 的一个错误.

• Using .NETPortable v5.0 instead. Too many missing classes here.
• Using .NETCoreApp v1.0 instead. Every class is missing. Did I use a wrong version?
• Using DNXCore. No missing classes. Just one error from VS.

我应该使用什么来代替 DNXCore 5.0?我需要最新的 API，比如 TlsStream 和 Uri，东西不存在 或者有没有办法强制编译器编译?请注意，当我使用 VS 2015 进行编译时，这是一个工作库.现在我已经切换到 VS 2017，我不能再编译我的项目了！在 .NET Core 或 .NET Portable 中.

What should I use instead of DNXCore 5.0? I need the latest APIs like TlsStream and Uri, stuff not present Or is there a way to force the compiler to compile? Please note this was a working library when I used VS 2015 to compile. Now that I've switched to VS 2017 I cannot compile my project anymore! in either .NET Core or .NET Portable.

推荐答案

嗯，这很令人惊讶！

我的库使用 .NETStandard v1.6 成功编译！

My lib successfully compiled with .NETStandard v1.6!
