Click Once 和 .NET Standard 兼容性问题
最近使用Click Once打包使用.NET Standard库的WPF应用时，出现一些无法加载库文件的异常，例如：
Unable to initialize the application (Could not load file or assembly 'System.Runtime, Version=4.1.1.0, Culture=neutral,
PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The System cannot find the file specified.
这是一个Bug，https://github.com/dotnet/standard/issues/529
关于.NET Standard lib引用说明的文章：https://andrewlock.net/what-is-the-netstandard-library-metapackage/
微软给出了一个Workaround：
在***.csproj中添加如下代码，即可解决
