  Hi Guys, With the immense hype created by ChatGPT every technology is adopting ways to integrate ChatGPT to their frameworks. Hence, a brilliant team led by Hassan Habib  has managed to give .NET Developers a way to call ChatGPT programmatically and get the responses. Remember this is still a new project you might encounter some issues, but the Standard.AI.OpenAI team is ready to help us developers in this journey. The source code can be found here. 1) First you must register yourself at https://platform.openai.com 2) Then you must generate an API Key as shown below. 3) Now you can start integrating your .NET Core applications to use openai. For this purpose I use a console application (.NET 7).  4) Install the Nuget package Standard.AI.OpenAI 5) Copy paste the below code using Microsoft.AspNetCore.Mvc; using Standard.AI.OpenAI.Brokers.DateTimes; using Standard.AI.OpenAI.Clients.OpenAIs; using Standard.AI.OpenAI.Models.Configurations; using Standard.AI.OpenAI.Models.Services.Foundati

I created a windows application to achieve this task. The following are two methods which I used to check the status and if it is stopped to start the application pool.    private string GetpoolStatus(string computerName,string appPoolName)         {             Runspace runspace = System.Management.Automation.Runspaces.RunspaceFactory.CreateRunspace();                          PowerShell powershell = PowerShell.Create();                          PSCommand command = new PSCommand();             string result = "";             ScriptBlock scriptBlock = ScriptBlock.Create("Import-Module WebAdministration; Get-WebAppPoolState -NAME " + appPoolName + "");             command.AddCommand("Invoke-Command").AddParameter("ComputerName", computerName).             AddParameter
