.net core 2.2發布后支持System.Drawing.Common繪圖，可以做一些圖片驗證碼之類的功能，應用程序在Windows上運行功能正常，但是部署到centos上就會報錯：
System.TypeInitializationException: The type initializer for 'System.DrawingCore.GDIPlus' threw an exception. ---> System.DllNotFoundException: Unable to load shared library 'gdiplus' or one of its dependencies. In order to help diagnose loading problems, consider setting the LD_DEBUG environment variable: libgdiplus: cannot open shared object file: No such file or directory
解決辦法：
centos上安裝libgdiplus-devel；
命令如下：yum install libgdiplus-devel
安裝完成后重啟 .net core 服務 OK！
