…alue.
This adds an escape hatch (setting 'UseDefaultPublishRuntimeIdentifier=false') when trying to set a default PublishRuntimeIdentifier value.
This is necessary when publishing with RuntimeIdentifiers (plural), but without a RuntimeIdentifier, which is valid when building universal apps for macOS and Mac Catalyst (the netX-macos and netX-maccatalyst target frameworks).
When building such an app, the project file will set RuntimeIdentifiers (plural):
<TargetFramework>net11.0-macos</TargetFramework>
<RuntimeIdentifiers>osx-x64;osx-arm</RuntimeIdentifiers>
and then during build/publish, the macOS SDK will run two inner builds, with RuntimeIdentifiers unset, and RuntimeIdentifier set to each of the rids (and at the end merge the result into a single app).
The problem is that the outer build, where RuntimeIdentifiers is set, but RuntimeIdentifier isn't, PublishRuntimeIdentifier will now get a default value (after PR #51765), and that will set RuntimeIdentifier, which will confuse our outer build.
Also note that we can't set PublishRuntimeIdentifier to the desired runtime identifiers (plural), because PublishRuntimeIdentifier is only valid for a single runtime identifier.
