Binary DLL Migration
Use this skill for source-unavailable managed .dll or .exe inputs.
Workflow
-
Confirm the input is a managed assembly. The CLI reports unreadable/native binaries without mutating them.
-
Run direct analysis. Direct DLL/EXE inputs are decompiled automatically:
dotnet run --project src/MigrateToWinUI.Cli -- analyze <assembly.dll> --source auto --target both --format json --report out/binary/analysis.json
- For artifact-producing runs, use
decompile:
dotnet run --project src/MigrateToWinUI.Cli -- decompile <assembly.dll> --source wpf --target winui3 --out out/binary/decompiled --report out/binary/report.json --preview out/binary/preview.txt
- Include local UI references only when you need referenced application libraries:
dotnet run --project src/MigrateToWinUI.Cli -- decompile <assembly.dll> --include-references --source wpf --target both --out out/binary/full
Review Gates
- Framework/reference assemblies are skipped.
- BAML resources are manual-review and must not produce safe XAML rewrite claims.
- Decompiled locations are synthetic unless backed by original PDB/source evidence.
- Decompiler warnings, unresolved references, and resource extraction notes are migration findings.
Outputs
- Decompiled C# projection files.
- Recovered loose XAML/resources when possible.

- Migration report and optional rewrite preview.
