ProcessInfo Linux/Windows incompatibility

Question

I'm trying to run same process as a child of current process. Showed below code works just fine under windows, but fails in Linux with error

No executable found matching command "dotnet-MyDll.dll"

var processInfo = new ProcessStartInfo
        {
            FileName = "dotnet",
            Arguments = "MyDll.dll " + id.ToString()
        };

        Console.WriteLine("Starting child process...");
        var process = Process.Start(processInfo);
        return process;

Ive also tried FileName = "dotnet MyDll.dll"+ id.ToString(), but it ends up with different error Unhandled Exception: System.ComponentModel.Win32Exception: No such file or directory

I've also tried

    var parentP = Process.GetCurrentProcess();
    string fullPath = parentP.MainModule.FileName;
    var command = fullPath+" "+Assembly.GetEntryAssembly().Location+" "+ id.ToString();
    Console.WriteLine("Command = "+command);
    var processInfo = new ProcessStartInfo
    {
        FileName = command
    };
    var process = Process.Start(processInfo);

Still Unhandled Exception: System.ComponentModel.Win32Exception: No such file or directory

I've also tried:

var parrentP = Process.GetCurrentProcess();
    string fullPath = parrentP.MainModule.FileName;
    var command = "\"" + fullPath + "\" " ;
    var args = Assembly.GetEntryAssembly().Location + " " + id;
    var processInfo = new ProcessStartInfo
    {
        FileName = command,
        Arguments = args
    };
        var process = Process.Start(processInfo);

Exception No such file or directory
Exception at System.Diagnostics.Process.StartCore(ProcessStartInfo startInfo)
at System.Diagnostics.Process.Start()
at System.Diagnostics.Process.Start(ProcessStartInfo startInfo)

what is proper way of running currently running dll again under Linux with dotnet core
