Description
I try to use System.Threading Mutex(bool initiallyOwned, string? name, out bool createdNew) on macOS in a net6 project.
The name I use contain a slash ("/"). On windows I have no issue with it, but on macOS, I have an exception :
System.IO.IOException: The filename, directory name, or volume label syntax is incorrect. : '6dace8f3-282b-4b6e-ab0b-99026a8fb613/c8cf2963-3b12-4537-8a44-4aac2dad98dc'
at System.Threading.Mutex.CreateMutexCore(Boolean initiallyOwned, String name, Boolean& createdNew)
at System.Threading.Mutex..ctor(Boolean initiallyOwned, String name, Boolean& createdNew)
There are no such of restriction in the documentation, only the backslash is reserved.
https://docs.microsoft.com/en-us/dotnet/api/system.threading.mutex?view=net-6.0
The backslash (\) is a reserved character in a mutex name. Don't use a backslash (\) in a mutex name except as specified in the note on using mutexes in terminal server sessions. Otherwise, a [DirectoryNotFoundException](https://docs.microsoft.com/en-us/dotnet/api/system.io.directorynotfoundexception?view=net-6.0) may be thrown, even though the name of the mutex represents an existing file.
It could be good to add the / as reserved.
Reproduction Steps
Mutex mutex = new Mutex(true, "1234/5678", out var isCreatedNew);
Expected behavior
no exception or invalid name
Actual behavior
launch an exception
Regression?
No response
Known Workarounds
