+### Code Formatting
+
+Before committing any changes, format the codebase using the following command to ensure consistent code style:
+
+```bash
+dotnet format Microsoft.Maui.sln --no-restore --exclude Templates/src --exclude-diagnostics CA1822
+```
+
+This command:
+- Formats all code files according to the repository's `.editorconfig` settings
+- Excludes the Templates/src directory from formatting
+- Excludes the CA1822 diagnostic (member can be marked as static)
+- Uses `--no-restore` for faster execution when dependencies are already restored
