问题描述
对此有一个类似的问题
There is a similar question to this here but I believe that involves a different cause.
I moved a class from a newer project into an older project. Both were targeting .net 4.6 however after the move I received the following error on build.
I tried setting my project to build with C# 6 in the properties window with no change.
解决方案
I eventually found the place to change it. It seems sometimes when you update your targets framework version this does not get changed.
