WPF and C# Code Formatting

Applies consistent code style to XAML and C# files.

1. Required Tools

# Verify .NET 10 is available
dotnet --version  # Should be 10.0.x or higher

Run via dotnet dnx (dotnet tool runner). No manual installation required.

dotnet format (C# Formatting)

Included with .NET SDK by default.

2. Configuration Files

Template location: templates/Settings.XamlStyler

Key settings:

• AttributesTolerance: 1 - Allow up to 1 attribute on same line
• KeepFirstAttributeOnSameLine: true - Keep first attribute on element line

3. Formatting Commands

XAML Formatting

# Format all XAML files in workspace
dotnet dnx -y XamlStyler.Console -- -d "{workspace}" -r -c "{workspace}/Settings.XamlStyler"

# Format single file
dotnet dnx -y XamlStyler.Console -- -f "{file.xaml}" -c "{workspace}/Settings.XamlStyler"

dotnet dnx Options:

• -y: Auto-accept confirmation prompt
• --: Separator between dnx options and tool arguments

XamlStyler Options:

• -d: Target directory
• -f: Target file
• -r: Recursive processing
• -c: Configuration file path

C# Formatting

# Format entire solution
dotnet format "{solution.sln}" --no-restore

# Format specific project only
dotnet format "{project.csproj}" --no-restore

# Format single file
dotnet format "{project.csproj}" --include "{file.cs}" --no-restore

Options:

• --no-restore: Skip NuGet restore (faster)
• --include: Target specific file

4. Workflow

Full Formatting

Task Progress:
- [ ] Step 1: Check if Settings.XamlStyler exists, create if not
- [ ] Step 2: Check if .editorconfig exists, create if not
- [ ] Step 3: Run dotnet dnx XamlStyler.Console for XAML formatting
- [ ] Step 4: Run dotnet format for C# formatting

Per-file Formatting (Hook Usage)

- When .xaml file modified: Run dotnet dnx XamlStyler.Console
- When .cs file modified: Run dotnet format

• Check git status: Verify uncommitted changes before formatting
• Binary exclusion: bin/, obj/ folders automatically excluded
