Ensure that C# types are documented with XML comments and follow best practices for documentation

# C# Documentation Best Practices

- Public members should be documented with XML comments.
- It is encouraged to document internal members as well, especially if they are complex or not self-explanatory.

## Guidance for all APIs

- Use `<summary>` to provide a brief, one sentence, description of what the type or member does. Start the summary with a present-tense, third-person verb.
- Use `<remarks>` for additional information, which can include implementation details, usage notes, or any other relevant context.
- Use `<see langword>` for language-specific keywords like `null`, `true`, `false`, `int`, `bool`, etc.
- Use `<c>` for inline code snippets.
- Use `<example>` for usage examples on how to use the member.
  - Use `<code>` for code blocks. `<code>` tags should be placed within an `<example>` tag. Add the language of the code example using the `language` attribute, for example, `<code language="csharp">`.
- Use `<see cref>` to reference other types or members inline (in a sentence).
- Use `<seealso>` for standalone (not in a sentence) references to other types or members in the "See also" section of the online docs.
- Use `<inheritdoc/>` to inherit documentation from base classes or interfaces.
  - Unless there is major behavior change, in which case you should document the differences.

## Methods

- Use `<param>` to describe method parameters.
  - The description should be a noun phrase that doesn't specify the data type.
  - Begin with an introductory article.
  - If the parameter is a flag enum, start the description with "A bitwise combination of the enumeration values that specifies...".
  - If the parameter is a non-flag enum, start the description with "One of the enumeration values that specifies...".
