Documentation

Use XML documentation comments for public APIs:

/// <summary>
/// Brief description.
/// </summary>
/// <param name="name">Description.</param>
/// <returns>Description.</returns>
/// <exception cref="ExceptionType">When condition.</exception>

Formatting

C# files are formatted with dotnet format (style + whitespace). Run ./go format after changes; it will auto-fix most violations.

Key rules enforced (from dotnet/.editorconfig):

• Namespaces: file-scoped (namespace Foo.Bar; not block-wrapped)
• Using directives: placed outside the namespace block; System namespaces sorted first
• Braces: Allman style — opening brace on its own line for all blocks
• Spacing: no space after cast, space after commas, space around binary operators
• Remove unnecessary using directives (IDE0005 treated as warning)
