Enable WSL solution builds

 Run `nuget restore LIAM.sln` once per clone to hydrate packages. Build locally with `msbuild LIAM.sln /p:Configuration=Debug`; use `Release` for deployable artifacts. For a clean rebuild, execute `msbuild LIAM.sln /t:Clean,Build /p:Configuration=Debug`. Visual Studio can open `LIAM.sln`, with `LiamM42WebApi` as the suggested startup project. When self-hosting the API, deploy it to IIS or IIS Express pointing at the project folder.
 
+On WSL/Linux, use the user-local `msbuild` wrapper that delegates to `dotnet msbuild` with the local .NET Framework reference assemblies under `~/.local/share/dotnet-framework-reference-assemblies/`. The expected verification command there is still `msbuild LIAM.sln /p:Configuration=Debug`. `LiamWorkflowDiagnostics` is a WPF diagnostics tool and is intentionally skipped on non-Windows builds; validate that project on Windows with Visual Studio or Windows MSBuild. If you only need to validate the NTFS provider in isolation, `msbuild LiamNtfs/LiamNtfs.csproj /p:Configuration=Debug` is the fastest targeted check.

 ## Coding Style & Naming Conventions
 
 Follow C# Allman braces with four-space indentation. Maintain `PascalCase` for classes, members, and constants (e.g., `constFragmentNameConfigProviderBase`), and `camelCase` for locals and parameters. Keep `using` directives sorted and trimmed. New projects should link `SharedAssemblyInfo.cs` to align assembly metadata. Format via Visual Studio or `dotnet format` if the SDK is available.
