Pull request overview
This PR fixes a regression in the WebAssembly build process where satellite assemblies from NuGet packages containing multiple cultures were incorrectly flagged as duplicate files. The fix ensures that satellite assemblies, which are deployed to culture-specific subdirectories, bypass the unique filename check that only applies to assemblies in the main framework folder.
Changes:
- Modified
ComputeWasmBuildAssets.csto skip the unique filename check for satellite assemblies with culture metadata - Added comprehensive test coverage including a new French localization and a test specifically for package-sourced satellite assemblies
