Jellyfin 12.0.0 targets net10.0, and the .NET 8 SDK refuses to even restore
a project that lists net10.0 among its TargetFrameworks (NETSDK1045) -- so
the multi-targeted net8.0;net10.0 build that will produce one plugin DLL per
Jellyfin generation cannot start until the builder image moves first.
Verified as a drop-in against the current net8-only master, inside the image:
restore + build are clean (0 errors, 0 warnings) and jprm produces the same
two-file zip as before. Analyzer levels still track each TFM, so the net8.0
leg stays warning-free; CA1873 will only need silencing on the net10.0 leg
once multi-targeting lands.
