Booleans (flags) - If true or false is passed for an option having a bool argument, it is parsed and bound as expected. But an option whose argument type is bool doesn't require an argument to be specified. The presence of the option token on the command line, with no argument following it, results in a value of true.
Enums - The values are bound by name, and the binding is case insensitive
Common CLR types:
- FileSystemInfo, FileInfo, DirectoryInfo
- int, long, short, uint, ulong, ushort
- double, float, decimal
- byte, sbyte
- DateTime, DateTimeOffset, TimeSpan, DateOnly, TimeOnly
- Guid
- Uri, IPAddress, IPEndPoint
Any type with a public constructor or a static Parse method with a string parameter (other parameters, if any, should be optional) - These types can be bound/parsed automatically even if they are wrapped with Enumerable or Nullable type.

Arrays, lists, collections:
- Any type that implements IEnumerable<T> and has a public constructor with a IEnumerable<T> or IList<T> parameter (other parameters, if any, should be optional). CLR collection types already satisfy this condition.
- If type is generic IEnumerable<T>, IList<T>, ICollection<T> interfaces itself, array T[] will be used to create an instance.
- If type is non-generic IEnumerable, IList, ICollection interfaces itself, array string[] will be used to create an instance.
