oqtane.framework: Cannot find compilation library location for package 'System.Drawing.Common'

While testing our oqtane module instalation to see that all referenced 3rd party dependencies are included in nupkg I got the error: “Cannot find compilation library location for package ‘System.Drawing.Common’”.

The error happens in clean oqtane 2.0.2 installation, hosted on IIS 10, while running our module instance on the page. I’m not aware that we are using anything from System.Drawing.Common, but we are using oqtane framework a lot, so I search for it in the oqtane source code and I see that is added as a package reference to Oqtane.Server project.

<PackageReference Include="System.Drawing.Common" Version="5.0.0" />

Is it possible that this dll have to be included as part of the oqtane install zip?

If not, we need to include in our oqtane module nupkg because it is not working without it.
