问题

使用.NET Core2.1创建AutoCAD插件时报错：

WRN: Assembly binding logging is turned OFF.

To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.

Note: There is some performance penalty associated with assembly bind failure logging.

To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

AutoCAD.NET API需要完全.NET framework。不能使用.NET Core/.NET Standard .NET API编程（最新的.NET技术命名非常混乱，很难跟踪/解释/理解）

什么时候AutoCAD .NET支持.NET Core/.NET6+？？？
