Specifying MutexSecurity for a named global mutex in .NET Core

Question

Is there a way to pass MutexSecurity to a Mutex in .NET Core (currently still using 2.2, switching to .NET 6 in the future)?

.NET Framework has a constructor accepting this parameter, but it seems to have been removed in .NET Core.

Answer 1

In .NET 6.0 there is the MutexAcl class:

#if NET6_0_OR_LATER
    using (var mutex = MutexAcl.Create(false, mutexId, out bool createdNew, securitySettings))
#else
    using (var mutex = new Mutex(false, mutexId, out bool createdNew, securitySettings))
#endif

Which is available through the System.Threading.AccessControl nuget package.

The method will throw PlatformNotSupportedException if not on Windows (naturally).
