Description

All the Tests applications listed below run for net6.0, netcoreapp3.1, net462, on Windows (.github/workflows/runtests.yml):

• Tests/Svg.Benchmark
• Tests/Svg.UnitTests
• Tests/SvgW3CTestRunner

<TargetFrameworks>net6.0;netcoreapp3.1;net462</TargetFrameworks>

The target of the SVG-NET library, however, include netstandard2.0 and netstandard2.1, as shown below:

<TargetFrameworks>net6.0;netcoreapp3.1;netstandard2.1;netstandard2.0;net462</TargetFrameworks>

Question

Which platforms or use cases are there (or targeted) for the netstandard2.1 and netstandard2.0?
Scanning the issues report, it seems there are mix results on the support of the .NET Standard, with regards to the System.Drawing and System.Drawing.Common. It seems someone got it working in web environment - ASP.NET (cannot remember the OS).

I remember @wieslawsoltes having run the tests under Linux (don't remember which .NET version, must have been an older one), and a lot of the tests failing due to the problems with libgdiplus, I think.
In the long run, it would be helpful to have tests for different systems.
