为什么c#不等待python代码完成？

using System;
using System.Diagnostics;

class Program
{
    static void Main()
    {
        Process process = new Process();
        process.StartInfo.FileName = "python";
        process.StartInfo.Arguments = "your_script.py";
        process.StartInfo.UseShellExecute = false;
        process.StartInfo.RedirectStandardOutput = true;
        process.StartInfo.CreateNoWindow = true;

        process.Start();
        string output = process.StandardOutput.ReadToEnd();
        process.WaitForExit();

        Console.WriteLine(output);
    }
}

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

class Program
{
    static async Task Main(string[] args)
    {
        Process process = new Process();
        process.StartInfo.FileName = "python";
        process.StartInfo.Arguments = "your_script.py";
        process.StartInfo.UseShellExecute = false;
        process.StartInfo.RedirectStandardOutput = true;
        process.StartInfo.CreateNoWindow = true;

        process.Start();
        string output = await process.StandardOutput.ReadToEndAsync();
        await process.WaitForExitAsync();

        Console.WriteLine(output);
    }
}
