Add reference to netNamedPipeBinding in .Net 5

i have class library project in .net framework 4.6.1. i have to migrate that project into .net 5. while doing so I am facing error for netNamedPipeBinding.

Severity    Code    Description Project File    Line    Suppression State
Error   CS0246  The type or namespace name 'NetNamedPipeBinding' could not be found (are you missing a using directive or an assembly reference?)    

following nuget package already installed.

System.ServiceModel.Duplex
System.ServiceModel.Http
System.ServiceModel.NetTcp
System.ServiceModel.Primitives

Any way to to make it work?

Looks like it is not supported.

Named pipes
WCF provided a named pipes binding for communication between processes on the same physical machine. The first release of ASP.NET Core gRPC does not support named pipes. Adding client and server support for named pipes (and Unix domain sockets) is a goal for a future release.

Also, the documentation page for NamedPipeBinding is resolved to .NET 4.8 section and does not exist for .NET 5

HttpBinding documentation page is there for .NET 5
