I can build, but when running the 0.3 plugins are still installable (I copied the binary manually).
GitExtensions.Extensibility.dll is from January, not updated for some reason also with full match - then the package is not found.
Tests fail, but they try to test with latest 5.2.1

It is built (and of course require) .net8 and do not limit 0.3 plugins

GitExtensions.Extensibility.dll is not coming from
GitExtensions.Extensibility package (see gitextensions/gitextensions.extensibility#31). It is still in the main repo. To get a newer dll (and the whole Git Extensions) you need to delete the GitExtensions.Shared folder one level above the PluginManager repository. If there is no Git Extensions portable found, it tries to download latest.

I have validated local build - it requires .NET 9 to run Git Extensions (6.0.1.18221). The plugin manager can start from the plugins menu and search for packages. It filters out packages correctly.

There is a bit of a problem with how existing nuget plugins define a dependency on GitExtensions.Extensibility, for example https://www.nuget.org/packages/GitExtensions.GerritPlugin/1.3.1.116#dependencies-body-tab (a historic version of Gerrit), it states is supports [0.1.0, 1.0.0) which is incorrect. Newer versions have it setup correctly, like [0.3.0, 0.4.0) for previous Git Extensions version. For Git Extensions v6 it should be [0.4.0, 0.5.0). We might want hide the historic versions on nuget.org to prevent a confusion.

I unlisted 1.3.1.116, thanks
Do you think we should unlist any others?

Yep :( I couldn't win that argument, so the extensibility API are in the main repo.
