Reader 5.0.0.71 doesn't work on MacOS (is fine on Win and Linux)

[chhh]

Using .NetStandard 2.0 nuget packages version 5.0.0.71 from this repo I can't read RAW files on MacOS.

Try creating a reader and getting any information. The file error information reported by the reader is not informative (code 2).
So I installed a FirstChanceException handler (https://docs.microsoft.com/en-us/dotnet/framework/app-domains/how-to-receive-first-chance-exception-notifications):

AppDomain.CurrentDomain.FirstChanceException += (_, e) => {
        Console.WriteLine($"FirstChanceException event #{Interlocked.Increment(ref _firstChanceCount)}" +
                          $"\tType: {e.Exception.GetType().Name}\n" +
                          $"\tSource: {e.Exception.Source}\n" +
                          $"\tMessage: {e.Exception.Message}");
      };

And the output is:

FirstChanceException event #1  Type: PlatformNotSupportedException
    Source: System.IO.MemoryMappedFiles
    Message: Named maps are not supported.
FirstChanceException event #2  Type: NullReferenceException
    Source: ThermoFisher.CommonCore.RawFileReader
    Message: Object reference not set to an instance of an object.
FirstChanceException event #3  Type: TargetInvocationException
    Source: System.Private.CoreLib
    Message: Exception has been thrown by the target of an invocation.
FirstChanceException event #4  Type: NUnitException
    Source: nunit.framework
    Message: Rethrown

So looks like there's some issue with memory mapped files. But it all works fine on Linux. I guess, should be working on MacOS as well.

The stacktrace does show that it's somewhere in RawFileLoader's constructor. I didn't understand what the error was about at first, and then read that named memory mapped files are a windows-only feature. However, at the same time, the reader works fine on Linux. Can it be that this constructor has some Windows-specific code path that is erroneously being taken on Mac, but some other code path is taken when running on Linux?

Dmitry, I haven’t tried the latest version of MacOS, but I know in the past that I haven’t had an issues in reading a RAW file on MacOS. Let me give it a try and get back to you. It may not be right away.
