C# tuple properties are seen as not documented

[Labouh]

Describe the bug
when using tupple in C# like

/// <summary>
/// Tuple seem as not documented
/// </summary>
public (int, int) Tupple { get; }

Doxygen see the defition as uncommented (but it was):
Main.cs(10): warning: Member Tupple (property) of class Test is not documented.

Moreover, the generate documentation is wrong (it does not mention the Tupple property, but see it as a data menber called int (??):

Are there currently any plans to address this issue? I'm encountering this currently. If there are currently no plans to address this issue, would the maintainers be open to a PR fixing this? I wouldn't be opposed to doing it, but have never worked on Doxygen before, so it would be nice if someone could point me in the right direction.

By the way-- for other C# devs encountering this issue, you can mitigate this by using the System.ValueTuple<> syntax instead of the parenthesis syntax. For instance:

private ValueTuple<int, int> tuple;

public void SetTuple((int, int) tuple)
{
    this.tuple = tuple;
}

I also ran into this with a method and can confirm that by changing the return type to a single value doxygen generated the doc. But with the tuple it says it's not documented.

Simplified example:

		/// <summary>
		///     Returns both GUID and local File ID.
		/// </summary>
		/// <param name="obj"></param>
		/// <returns></returns>
		public static (GUID, Int64) GetGuidAndFileId(Object obj)
		{
			return (new GUID(), 0L);
		}

Changing return value to ValueTuple works as per suggestion by @computablee :

public static ValueTuple<GUID, Int64> GetGuidAndFileId(Object obj)

But the output of course also lists ValueTuple<> as return type:
