Publishing with dotnet publish -r <rid>

The native binary in this package is built against Ubuntu-specific library versions (ffmpeg, GTK, ICU, and others), so it is intentionally not published under a portable RID such as linux-x64 -- doing so would let it install on other distros where it would fail at runtime instead of at install/build time.

For a normal build or dotnet run (no explicit -r), no extra configuration is needed: this package's own build\*.props sets <UseRidGraph>true</UseRidGraph> automatically, and the native library is copied to your output folder as part of the build.

If you publish with an explicit runtime identifier, e.g.

dotnet publish -r ubuntu-x64

you additionally need to add the following to your own .csproj (or a Directory.Build.props), using whichever of this package's RIDs (ubuntu-x64) matches your target architecture:

<PropertyGroup>
  <RuntimeIdentifier>ubuntu-x64</RuntimeIdentifier>
  <UseRidGraph>true</UseRidGraph>
</PropertyGroup>

This is required because NuGet's runtime-asset selection for a publish-time RID happens during restore, before any package's own build props are imported -- so a package cannot set this property for you in that scenario.

Note: the RuntimeIdentifier used above (ubuntu-x64) is the plain RID to target -- not the versioned package name (e.g. ubuntu-24.04-x64). The version in the package name only tells you which native binary to install (matching your target Ubuntu release); the RuntimeIdentifier your project targets stays the plain form, e.g. ubuntu-x64, regardless of which versioned package you reference.

Publishing to a generic RID (dotnet publish -r linux-x64) is not supported by this package: publish-time asset selection can only narrow from a generic RID to a more specific one, not the other way around, and this package deliberately does not ship its native binary under a generic RID.
