SerialNumberFetcher is a C# class designed to fetch the BIOS serial numbers of remote computers asynchronously in parallel using PsExec.

• Asynchronous execution of commands.
• Parallel processing with a limit on the maximum number of concurrent tasks.
• Command timeout and retry mechanism.
• Logging of attempts and errors.

The SerialNumberFetcher class includes the following methods:

• FetchSerialNumbersAsync: This method fetches the serial numbers for a collection of computers.
• FetchSerialNumberWithRetryAsync: This method attempts to fetch the serial number with retries.
• GetSerialNumberAsync: This method runs the PsExec command to get the serial number.
• ExecuteCommandAsync: This method executes the command and captures the output.
• ParseSerialNumber: This method parses the output to extract the serial number.

Here is an example of how to use the SerialNumberFetcher class within a larger program:

using System;
using System.Collections.Generic;
using System.Threading.Tasks;

public static async Task Foo()
{
    var computers = new List<Computer>
    {
        new Computer { Name = "Computer1" },
        new Computer { Name = "Computer2" },
        // Add more computers as needed
    };

    var fetcher = new SerialNumberFetcher();

    await fetcher.FetchSerialNumbersAsync(computers, 
        computer => computer.Name, 
        (computer, serial) => computer.SerialNumber = serial);

    foreach (var computer in computers)
    {
        Console.WriteLine($"Name: {computer.Name}, Serial Number: {computer.SerialNumber}");
    }
}

public class Computer
{
    public string Name { get; set; }
    public string SerialNumber { get; set; }
}
