Wslhub.Sdk 사용으로 알아보는 CoInitializeSecurity 사용 제약

남정현 님이 nuget에 공개한 Wslhub.Sdk 패키지는,

Wslhub.Sdk
; https://www.nuget.org/packages/Wslhub.Sdk/

using Wslhub.Sdk;

// Place the code Wsl.InitializeSecurityModel() at the top of your application's Main() method.
Wsl.InitializeSecurity();

// Assert WSL installation status
Wsl.AssertWslSupported();

// Enumerate distro list
var distros = Wsl.GetDistroListFromRegistry();

// Query distro informations
var queryResults = Wsl.GetDistroQueryResult();

// Run a command
var result = Wsl.RunWslCommand(distroName, "cat /etc/passwd");

// Run a command with default distro
var defaultDistro = Wsl.GetDefaultDistro();
var result = defaultDistro.RunWslCommand("cat /etc/passwd");
Stream Redirection
using var outputStream = new MemoryStream();

var defaultDistro = Wsl.GetDefaultDistro();
defaultDistro.RunWslCommand("ls /dev | gzip -", outputStream);

outputStream.Seek(0L, SeekOrigin.Begin);
using var gzStream = new GZipStream(outputStream, CompressionMode.Decompress, true);
using var streamReader = new StreamReader(gzStream, new UTF8Encoding(false), false);
var content = streamReader.ReadToEnd();

Console.Out.WriteLine(content);

public static void InitializeSecurityModel()
{
    var result = NativeMethods.CoInitializeSecurity(
        IntPtr.Zero,
        (-1),
        IntPtr.Zero,
        IntPtr.Zero,
        NativeMethods.RpcAuthnLevel.Default,
        NativeMethods.RpcImpLevel.Impersonate,
        IntPtr.Zero,
        NativeMethods.EoAuthnCap.StaticCloaking,
        IntPtr.Zero);

    if (result != 0)
        throw new COMException("Cannot complete CoInitializeSecurity.", result);
}

var defaultDistro = Wsl.GetDefaultDistro();
var result = defaultDistro.RunWslCommand("cat /etc/passwd"); // 정상 동작

CoInitializeSecurity를 제대로 부르고 싶으면 결국은 네이티브의 힘을 빌릴 수밖에 없는 걸까요?
