Is it possible to add an argument for the pipe security when creating the pipe

[Marledonna]

I am using the PipeMethodCalls to communicate between a NET core 6 application as PipeServer and a Web API running under IIS as a PipeClient. In this particular situation I get the following error:

There is an overload that takes in a NamedPipeClientStream as long as you set PipeOptions.Asynchronous and PipeDirection.InOut on it. That should allow you to set whatever security options you like on the underlying pipe stream.
