Inter-process Mutex doesn't work for processes of different architectures on Apple Silicon #62140
Description
Description
It's impossible to synchronize .NET processes of different architectures (x64 and aarch64) using System.Threading.Mutex on Apple Silicon
Reproduction Steps
Let's create the following simple console application:
using System;
using System.Threading;
class Program {
static void Main(string[] args)
{
Mutex mutex = null;
try
{
mutex = new Mutex(false, "Global\\MyUniqueMutexName");
mutex.WaitOne();
Thread.Sleep(TimeSpan.FromSeconds(60));
}
catch (Exception ex) { Console.WriteLine(ex); }
finally { mutex?.ReleaseMutex(); }
}
}Then let's build it on Apple Silicon using two toolsets with .NET 6 - for x64 and aarch64.
And then launch them sequentially in any order.
Expected behavior
Both instances of the application run successfully and terminate ~60 seconds after the start of the first one (the second instance waits for the global mutex acquired by the first one).
Actual behavior
The second application is finished intermediately with following message
System.Threading.WaitHandleCannotBeOpenedException: A WaitHandle with system-wide name 'Global\MyUniqueMutexName' cannot be created. A WaitHandle of a different type might have the same name.
at System.Threading.Mutex.CreateMutexCore(Boolean initiallyOwned, String name, Boolean& createdNew)
at System.Threading.Mutex..ctor(Boolean initiallyOwned, String name)
at Program.Main(String[] args) in /Users/Valentin.Grigorev/RiderProjects/GlobalMutexExperiment2/x64App/Program.cs:line 11
