-    Stride Native Build Mode Configuration
-
-    Manages which toolchain is used for native C++ compilation and linking.
-
-    Build Modes:
-    - Msvc (default on Windows): Uses clang for compilation and MSVC linker for linking (Windows only)
-                                 Requires Visual Studio or MSVC toolset
-                                 Default for Windows builds to preserve existing behavior
-
-    - Clang:                     Uses clang for compilation and LLVM LLD for linking
-                                 Works on Windows, Linux, macOS, iOS, Android
-                                 RECOMMENDED: Cross-platform, no MSVC dependency
-                                 Default for non-Windows platforms
-
-    Usage:
-    1. Command line:
-       dotnet build /p:StrideNativeBuildMode=Clang
-
-    2. Environment variable:
-       set StrideNativeBuildMode=Clang
-
-    3. In .csproj/.props file:
-       <StrideNativeBuildMode>Clang</StrideNativeBuildMode>
-
-    4. User configuration file:
-       %APPDATA%\Stride\Stride.Build.props or similar
+    Native build mode: MSVC (clang + MSVC linker, Windows only) or Clang (clang + LLD, all platforms).
+    Override via -p:StrideNativeBuildMode=Clang|MSVC, env var, or property.
