Platform matrix

Media Blocks SDK .Net

This page lists what works on which Unity build target — the matrix is filtered to the runtime that ships in the cumulative .unitypackage. For the SDK-wide feature matrix that covers all .NET project types (not just Unity), see Platform matrix (.NET).

Cumulative-package shipping

The cumulative .unitypackage contains the platforms its build was opted into. The package shipped from https://files.visioforge.com/unity/ carries:

  • Windows-x64 (always)
  • Android arm64
  • macOS Universal
  • iOS device arm64

If a private build skipped a platform with the matching -Include* switch left out, the package's PluginImporter slots for that platform are absent and Unity will fail to load the SDK when the Build Target is switched to it.
