Run .exe with DLLs in Azure Function

I want to execute a C++ .exe which depends on DLLs by means of Azure Functions. It works on my local machine as well as when starting the exe with kudo console.

Like in post Run .exe executable file in Azure Function suggested I prepared the run.csx and loaded up the .exe and DLLs in the same Folder "D:\home\site\wwwroot\QueueTriggerCSharp1\".

It works when no DLLs in the C++ Code is required. Otherwise C++ doesn't find the DLLs (which are in the same Folder as the .exe) and the exit code is -1073741701. I get the same exit code, if I don't upload the DLLs.

Where should I load the DLLs or could there be another reason for it?

The run.csx-Code:

using System;
using System.Threading;
using System.Diagnostics;

public static void Run(TimerInfo myTimer, TraceWriter log)
{
    System.Diagnostics.Process process = new System.Diagnostics.Process();
    string WorkingDirectoryInfo =@"D:\home\site\wwwroot\QueueTriggerCSharp1\";
    string ExeLocation = @"D:\home\site\wwwroot\QueueTriggerCSharp1\WriteDatebase2.exe";
    Process proc = new Process();
    ProcessStartInfo info = new ProcessStartInfo();
    info.WorkingDirectory = WorkingDirectoryInfo;
    log.Info($"WorkingDirectory: {info.WorkingDirectory}");
    info.FileName = ExeLocation;
    info.Arguments = "";
    info.UseShellExecute = false;
    info.CreateNoWindow = true;
    proc.StartInfo = info;
    proc.Start();
    proc.WaitForExit();
    int exitcode=proc.ExitCode;
    log.Info($"ExitCode: {exitcode}");
}

The same error occurs when I start the exe with a python azure function. Starting the python script in kudo console works.

Does anyone have similar issues?

Can anyone help me? Thanks!
