Bug NOTIMPLEMENTEDEXCEPTION is thrown when using System.IO.Pipes when building with IL2CPP

Supposedly this was fixed back in 2018.4.4f1, yet I am still getting the same error. This is preventing me from building out my software on IL2CPP and every time I need to try it on another Unity editor version, it takes roughly 8 or so hours to import.

This is a massive resource depriver and it takes days to test a single version. I am trying this on 2018.4.8f1, which is 4 versions later. These are all obviously LTS releases. I am not using the newest LTS as it has known performance issues with the animator and it will be detrimental considering I have up to 30 different characters with an animator attached on screen at once.

Here's the patch note in 2018.4.4f1:
IL2CPP: Added support for NamedPipeClientStream on Windows platforms. (1159863, 1160512)

and here is the corresponding issue tracker thread where it also says it has been fixed:

It obviously looks like the Unity devs may have only NamedPipeClientStream and not NamedPipeServerStream... however I have literally no clue why they'd do such a thing considering they're under the same namespace.

Also, as with further IL2CPP testing today, not being able to use the Process class for Process.Start() and Proccess.GetProcessByName() is pretty terrible too. If I got all 3 of those problems fixed I think I'd be peachy keen.

I appreciate the time anyone takes to help me here as I am starting to go into panic mode due to the fact that this completely breaks the functionality I've spent months developing. I also need to switch from mono to IL2CPP for other reasons and this specifically is holding me back.

Thanks.

I get this error for NamedPipeClientStream with IL2CPP (- Mono works fine -) on 2019.4.22 (LTS) on an Android device:

As @TJD269 was saying, the bug seems to have been reported and fixed before (https://issuetracker.unity3d.com/is...on-is-thrown-when-use-system-dot-io-dot-pipes)

I am unsure how to proceed here. @Tautvydas-Zilys are you saying this SHOULD work? If so, would this be fixed in the 2019.4.XX LTS branch (which we are stuck to atm) if I submit a bug for this?

 

On Unity 2019.4.31f1 Iam still getting this issue, fixed this by updating to Unity 2021.2.3f1
