just noticed that the .NET6 version of the assembly has a version of 6.1.1, while the .NET4 version has a version of 184.108.40.20636, and just declares a AssemblyInformationalVersion("220.127.116.11") attribute. Is this difference in versioning intentional? It irritated me slightly ;-).
I used the NuGet package.
Not sure what you mean by .NET 6 version.
There are .NET Framework 4.0 and .NET Standard 2.0 versions.
In the current WinSCP 6.1.1 release, both have version 1.14 and product version 6.1.1.
If you see any other numbers, please post some evidence (e.g. a screenshot).
