我在Visual Studio 2015中有一个很好的旧.NET Framework 4.7类库,目前使用的是
Microsoft.Extensions.Configuration NuGet package version 1.1.2.我正在尝试将其更新到
version 2.0,但我收到此错误：
Microsoft.Extensions.Configuration 2.0.0′. You are trying to install
this package into a project that targets ‘.NETFramework,Version=v4.7’,
but the package does not contain any assembly references or content
files that are compatible with that framework. For more information,
contact the package author.
我看到新版本仅支持.NETStandard 2.0.我是否必须在Visual Studio 2017中将所有项目转换为.NET Core或.NET Standard？
