Multiple MarkdownExporters not possible

[bstordrup]

I'm testing BenchmarkDotNet and would like to have the benchmark results exported to both GitHub markdown and Atlassian markdown. But I get the error

The exporter BenchmarkDotNet.Exporters.MarkdownExporter is already present in configuration. There may be unexpected results.

Is that by intention - and why is it not possible to export to both markdown formats in the same run?

Is that by intention

I really doubt that, it's most likely a bug on our side.

The issue is as far as I can see in the ImmutableConfigBuilder.GetExporters method. It makes a mergeDictionary by the System.Type - and that will be the same for both the GitHub MarkdownExporter and the Atlassian MarkdownExporter.

If the purpose is to avoid having for example GitHub MarkdownExporter twice in the merged list, I see the logic in going through the lists of exporters and remove duplicates. But it has to be on something else or more that just the System.Type.
