How can I use C# 7 with it?

推荐答案

您可以通过安装Nuget软件包

You can replace the compiler shipped with Visual Studio for a C# 7-enabled version by installing the Nuget package Microsoft.Net.Compilers:

引用此软件包将导致使用 C#和Visual Basic编译器中包含的特定版本 软件包，而不是任何系统安装的版本.

Referencing this package will cause the project to be built using the specific version of the C# and Visual Basic compilers contained in the package, as opposed to any system installed version.

没有迹象表明我可以在软件包页面上看到Visual Studio 2015是否正式支持此功能.到目前为止，我的不严格测试表明它可以正常运行，但并非不费吹灰之力-C#7代码可以编译，但是带有下划线红色的波浪线表示语法错误: 请注意，您还需要安装Nuget软件包 System.ValueTuple 使用新的C#7值元组功能.

There is no indication that I can see on the package page as to whether this is officially supported in Visual Studio 2015. My not-thorough tests so far indicate that it works but not painlessly - C# 7 code compiles, but is underlined with the red squiggly line which indicates a syntax error: Note that you will also need to install the Nuget package System.ValueTuple to use the new C# 7 value tuples features.
