HttpListener implements IDisposable but there is not Dispose() method, why and how can I dispose it?

#region Assembly System.Net.HttpListener, Version=8.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51
// C:\Program Files\dotnet\packs\Microsoft.NETCore.App.Ref\8.0.2\ref\net8.0\System.Net.HttpListener.dll
