I installed this into a dotnet 5 console app, and below is the list of dependencies it wanted to install. A lot of these are due to that System.Xml.XmlSerializer that the Furl.Http.Xml package depends on, which is only used for a single extension method. Its not going to stop me from using this package for my console utility (thanks, by the way), but you may want to consider slimming down the dependencies.
