We weren't able to migrate our WPF app to .NET Core 3.1 because MutexRights wasn't available. Hope it gets implemented soon.

Unsupported (per Portability Analyzer):
M:System.Threading.Mutex.TryOpenExisting(System.String,System.Security.AccessControl.MutexRights,System.Threading.Mutex@)

This requests is not WPF-specific and probably belongs to corefx (now in the dotnet/runtime repo)

That said as far as I can tell MutexRights still exists and is public. The TryOpenExisting method seems to have moved and the functionality now be covered by MutexAcl.Create or Mutex.OpenExisting if you don't need the rights check and just want to open a cross process mutex.

I posted this feature request here because it was related to migrating WPF app to .NET Core.

As for MutexRights, it's not there and we need to specify MutexRights.Synchronize.
