Dotnetcore安装nuget包时不能使用content中的文件

问题：用NUGET打包了一个asp.netcore的项目，试图安装到另一个asp.netcore项目中，除了自动添加引用外，还希望自动释放一些文件以供修改。这些操作以前在netframe中是正常的，脚本如下

参考

说解决了，但根据他的方法，我并没有解决：

https://q.cnblogs.com/q/114299/

https://github.com/NuGet/Home/issues/6548

老外最后也只能出个提示，让你手工复制

参考

https://weblog.west-wind.com/posts/2018/Jan/29/Distributing-Content-and-Showing-a-ReadMe-file-in-a-NET-Core-Nuget-Package

链接文件（没试过，估计是以前netframe直接添加文件，更新包会覆盖可能修改过的文件的原因，所以搞了个LINK），参考

http://blog.stashev.com/linking-a-file-from-a-nuget-package/

弹出readme，功能正常，参考

https://weblog.west-wind.com/posts/2018/Jan/29/Distributing-Content-and-Showing-a-ReadMe-file-in-a-NET-Core-Nuget-Package

PS操纵项目文件参考

PS的工作原理参考https://everydaylifein.net/netframework/running-powershell-scripts-during-nuget-package-installation-and-removal.html

最后没办法，添加了init.ps1用于复制文件，代码如下，该方法要求VS必须以管理员身份运行，但它工作也不是很稳定(只在首次安装时才执行)

效果图

不工作的时候切换到PM的控制台，会发现它试图工作，可手工执行，参考

https://docs.microsoft.com/zh-cn/nuget/tools/package-manager-console

附另一种build target的做法，会在项目中添加文件链接，生成时自动复制

参考nuget中的EMGU.CV包
