I am using freeSpirepdf in dotnet core 3.1 webapi project and deployment environment is linux. I am able to smoothly use freeSpirepdf locally/debug but when i publish and deploy api on linux server i am getting this issue :

System.TypeInitializationException: The type initializer for 'Gdip' threw an exception.

Hi,

Thank you for your inquiry.
Our Spire.PDF for NETCore uses System.Drawing.Common, which depends on Libgdiplus library. The windows system includes the Libgdiplus library by default, while the Linux and MacOS don't include it. Please install the Libgdiplus library independently on your Linux and try again. The following is the command to install Libgdiplus in Ubuntu and Centos

Ubuntu:
sudo apt-get install libgdiplus

CentOS:
yum whatprovides libgdiplus
yum install -y epel-release
yum install -y libgdiplus-2.10-10.el7.x86_64
yum install -y libgdiplus-devel

In addition, I suggest that you try the latest commercial version (Spire.PDF Pack(Hot Fix) Version:8.4.15), as it is more stable than the free one. If the problem still exists, please provide your test code, input document (if any) as well as your Linux system info for further investigation. You can attach your file here or send it to us via email (support@e-iceblue.com). Thank you in advance.
