.Net Core on Linux

[hspeedy]

Thanks for porting EPPlus to .Net Core! Great job! But I have encountered a little problem while testing on linux. One of it's dependencies seems to rely on on gdi32+ and so it doesn't load on linux.

Hi, Thanks. After installing the libgdiplus I could run the functional tests on Ubuntu More info

sudo apt-get update
sudo apt-get install libgdiplus

Failed tests are VBA related, because .NET Core lacks some of the encryption Algorithms.

Thanks for helping me. After installing libgduplus everything works fine. I'm using Linux Mint 18.

On Ubuntu 16.04, with installing libgduplus, it works fine. But on CentOS 7, after installing libgdiplus, it still can not load 'gdiplus' when I call 'AutoFitColumns()':

Error: The type initializer for 'System.Drawing.GDIPlus' threw an exception.
-->The type initializer for 'System.Drawing.GDIPlus' threw an exception.
-->Unable to load DLL 'gdiplus': The specified module could not be found.

By the way, gdipus is:

libgdiplus-2.10-9.el7.x86_64

I do not know how to fix it, just simply skip calling 'AutoFitColumns()' to avoid this error:

libgdiplus is part of the Mono project and you can find more info about how to resolve DllNotFoundException here:

• DllNotFoundException
• Problem: GDIPlusInit

I ran into this using VS2017 with docker integration. Solution was to add the following to my dockerfile

FROM microsoft/aspnetcore:2.0 
ARG source
RUN apt-get update                      #Add this line
RUN apt-get install -y libgdiplus   #Add this line

Thanks for helping out with this! I'm running on macOS, and I had to run the following command to get it to work: brew install mono-libgdiplus
