Could not load file or assembly 'System.Drawing.Common, Version=0.0.0.0, Culture=neutral

[rluisnpt1]

DotNetCore.NPOI 1.2.2

protected ISheet Sheet;

//for each result I usualy add an AutoSizeColumn.

However now I got a message "Could not load file or assembly 'System.Drawing.Common, Version=0.0.0.0, Culture=neutral"

for (var i = 0; i < Headers.Count; i++) { Sheet.AutoSizeColumn(i); }
