Question

我不能在C＃Interactive窗口中使用元组;我收到以下错误：

(1,15): error CS8137: Cannot define a class or member that utilizes tuples because the compiler required type 'System.Runtime.CompilerServices.TupleElementNamesAttribute' cannot be found. Are you missing a reference?
(1,15): error CS8179: Predefined type 'System.ValueTuple`2' is not defined or imported
(2,9): error CS0103: The name 'IsLiteralTypeName' does not exist in the current context
(2,47): error CS8179: Predefined type 'System.ValueTuple`2' is not defined or imported
(5,12): error CS8179: Predefined type 'System.ValueTuple`2' is not defined or imported

即使在我添加了对ValueType程序集的引用之后：

#r "D:\MyProject\packages\System.ValueTuple.4.3.1\lib\netstandard1.0\System.ValueTuple.dll"

如何使用C＃Interactive窗口中的值元组？

for Visual Studio 2017和

C:\Program Files (x86)\Microsoft Visual Studio\2017\<edition>\MSBuild\15.0\Bin\Roslyn\csi.rsp

用于命令行工具（csi.exe）
