Centos 7 Asp.net core 使用QRCoder 报“Unable to load DLL 'gdiplus'"

环境：

 Centos7

 .Net core 2.0

问题：

使用QRCoder 报“Unable to load DLL 'gdiplus'"

同 https://q.cnblogs.com/q/98966/

解决：

yum install libgdiplus-devel

注意：

yum install libgdiplus 后，在centos7 下，程序并不能运行成功还是报错，查看libgdiplus安装情况

rpm -qa |grep libgdiplus

rpm  -ql libgdiplus-2.10-9.el7.x86_64
在/usr/lib64下缺少libgdiplus.so文件
Centos7 需要通过安装libgdiplus-devel来解决

If I recall correctly, the  .so  file for  libgdiplus  is named  libgdiplus.so.0  on CentOS (see https://centos.pkgs.org/7/epel-x86_64/libgdiplus-2.10-9.el7.x86_64.rpm.html). CoreCompat.System.Drawing is looking for  libgdiplus.so  so that doesn't work.

On CentOS, you need to install the  libgdiplus-devel  package.
