Here I want to retrieve data from CRM and have registered it in Azure to to get Client Credentials and using it in below code:

using Microsoft.Crm.Sdk.Messages;
using Microsoft.IdentityModel.Clients.ActiveDirectory;
using Microsoft.Xrm.Sdk;
using Microsoft.Xrm.Sdk.WebServiceClient;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace CRM_WebAPI_Test1
{
    class Program
    {
        static void Main(string[] atrgs)
        {
            MainAsync();
        }
        static async void MainAsync()
        {
            try
            {
                string organizationUrl = "https://OrgName<<URL>>.com";
                string clientId = "xxxxxxxxx-xxxx-xxxx-b7ca-xxxx";
                string clientSecret = "key received from Azure App Registration";
                string aadInstance = "https://login.microsoftonline.com/";
                string tenantID = "orgname";

                ClientCredential clientCredentials = new ClientCredential(clientId, clientSecret);
                AuthenticationContext authenticationContext = new AuthenticationContext(aadInstance + tenantID);
                AuthenticationResult authenticationResult = await authenticationContext.AcquireTokenAsync(organizationUrl, clientCredentials);
                var requestedToken = authenticationResult.AccessToken;

                using (var sdkService = new OrganizationWebProxyClient(GetServiceUrl(organizationUrl), false))
                {
                    sdkService.HeaderToken = requestedToken;

                    OrganizationRequest request = new OrganizationRequest()
                    {
                        RequestName = "WhoAmI"
                    };

                    WhoAmIResponse response = sdkService.Execute(new WhoAmIRequest()) as WhoAmIResponse;
                    Console.WriteLine(response.UserId);

                    Console.WriteLine("Press any key to exit...");
                    Console.ReadLine();
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.ToString());

                Console.WriteLine("Press any key to exit...");
                Console.ReadLine();
            }
        }
        static private Uri GetServiceUrl(string organizationUrl)
        {
            return new Uri(organizationUrl + @"/xrmservices/2011/organization.svc/web?SdkClientVersion=8.2");
        }
    }
}

But when it come to line:

AuthenticationResult authenticationResult = await authenticationContext.AcquireTokenAsync(organizationUrl, clientCredentials);

It directly exists the program and not giving any output, not even hitting the catch exception part. Is there anything I am missing here?

Also, how to know the tenant name while registering the application in Azure AD?

UPDATE: [Updating in question because not able to write down whole error in comment section so please bare with it.] After applying code changes as suggestion it is throwing error as below:

Microsoft.IdentityModel.Clients.ActiveDirectory.AdalServiceException: AADSTS50001: The application named https://orgname.com was not found in the tenant named mydirectory.onmicrosoft.com.

首先，你正在使用一个async void你不应该做的函数（除了在你不能影响方法签名的事件处理程序中）。

所以它应该是这样的：

static void Main(string[] atrgs)
{
    MainAsync().GetAwaiter().GetResult();
}
static async Task MainAsync()
{
}

基本上在您的代码中，当它遇到等待时，它会返回到 Main 并且程序退出。

在 C# 7.2 中，您还可以声明 main 方法，async Task这样您就可以只声明await该方法。

您可以从 Azure 门户获取租户ID 。

  1. 打开 Azure AD 刀片
  2. 转到属性
  3. 您可以找到租户 ID

另一种选择是使用任何经过验证的域名（例如 mydirectory.onmicrosoft.com）。
