Error Message

error MSB4057: The target "_GetRestoreSettingsPerFramework" does not exist in the project.

Issue Summary:

When net9.0-browserwasm is included in the TargetFrameworksof the .csproj file, the following build commands fail:
dotnet build UnoApp2.csproj -c:Release -f:net9.0-android -r:android-arm64
dotnet build UnoApp2.csproj -c Release -f net9.0-ios -r iossimulator-x64

Error Details:

• The build fails specifically when using -r:android-arm64 or -r:iossimulator-x64.
• If net9.0-browserwasm is removed from TargetFrameworks, the commands work correctly.
• The issue does not occur if the -r (runtime identifier) option is omitted.
• This problem does not occur with .NET 8; the same project builds successfully with .NET 8.

Environment

.NET SDK Version: 9.0
VisualStudio 17.12.0
Windows 11

Expected behavior

The project should build successfully with .NET 9 using the specified commands, regardless of whether net9.0-browserwasm is included in the TargetFrameworks.

Thanks for the report.

This is likely a .NET SDK bug that we may not be able to fix from our end.

Still, in the meantime, it's best to set the RuntimeIdentifiers property:

dotnet build -c Release -f net9.0-ios -p:RuntimeIdentifiers=iossimulator-x64
