Unable to copy file to windows container

[makten]

I'm trying to copy a file over to a Windows container following cp example in the examples folder. The following is my code:

`public static async Task CopyFileToPodAsync2(IKubernetes client, string name, string nsp, string container, string sourceFilePath, string destinationFilePath, CancellationToken cancellationToken = default)
{
ValidatePathParameters(sourceFilePath, destinationFilePath);
var handler = new ExecAsyncCallback(async (stdIn, stdOut, stdError) =>
{
var fileInfo = new FileInfo(destinationFilePath);
try
{
using var memoryStream = new MemoryStream();
using var inputFileStream = File.OpenRead(sourceFilePath);
using var tarOutputStream = new TarOutputStream(memoryStream, Encoding.Default)
{
IsStreamOwner = false
};

        var fileSize = inputFileStream.Length;
        var entry = TarEntry.CreateTarEntry(fileInfo.Name);
        entry.Size = fileSize;

        tarOutputStream.PutNextEntry(entry);
        await inputFileStream.CopyToAsync(tarOutputStream);
        tarOutputStream.CloseEntry();

        memoryStream.Position = 0;

        await memoryStream.CopyToAsync(stdIn);
        await stdIn.FlushAsync();
    }
    catch (Exception ex)
    {
        throw new IOException($"Copy command failed: {ex.Message}");
    }

    using StreamReader streamReader = new StreamReader(stdError);
    while (!streamReader.EndOfStream)
    {
        string error = await streamReader.ReadToEndAsync();
        throw new IOException($"Copy command failed: {error}");
    }
});

string destinationFolder = GetFolderName(destinationFilePath);


// Use Windows-specific command to extract the tar stream to the destination folder
try
{
    var r = await client.NamespacedPodExecAsync(
        name,
        nsp,
        container,
        new string[] { "cmd", "/c", $"powershell -Command \"tar -xmf - -C {destinationFolder}\"" },
        false,
        handler,
        cancellationToken).ConfigureAwait(false);

    return r;
}
catch (Exception ex)
{
    throw new IOException($"Command execution failed: {ex.Message}");
}}` 

The destination folder is C:\Test which exists on the machine. Even when I create a new Folder adding mkdir C:\Test2 to the command, I do not get an error but nothing happens.
Could someone point out what I'm doing wrong?

@tg123 I'm using an image based on msmq-wcf-ltsc2022 (https://hub.docker.com/r/microsoft/dotnet-framework-wcf) My web application is running on a Microsoft Windows Server 2022 Datacenter. I hope that is the information you need.

@tg123 have you had time to check my issue?

Hi @makten
was in vacation :)

running image kubectl run wcf --image=mcr.microsoft.com/dotnet/framework/samples:wcfservice

code based on https://github.com/kubernetes-client/csharp/blob/master/examples/cp/Cp.cs
changes to code in example,

            return await client.NamespacedPodExecAsync(
                name,
                @namespace,
                container,
                //new string[] { "sh", "-c", $"tar xmf - -C {destinationFolder}" },
                new string[] { "cmd", "/c", $"tar xmf - -C {destinationFolder}" },
                false,
                handler,
                cancellationToken);
