Summary mistake

[psdlex]

I think you forgot to change the name of the property UsesConditionals in the summary of DefinedConditionals . (EvaluateConditionals in <see cref="EvaluateConditionals"/>)

/// <summary>
/// Determines whether the parser should evaluate conditional blocks ([$WINDOWS], etc.).
/// </summary>
public bool UsesConditionals = true;

/// <summary>
/// If <see cref="EvaluateConditionals"/> is set to true, only VDF properties 1) without any specified conditional logic or 2) conditional logic matching defined conditionals will be returned.
/// </summary>
public IReadOnlyList<string>? DefinedConditionals { get; set; }
