Now for this article first we will create a new asp.net core application and add the below mention app settings into it.

"Smtp": {     "Host": "smtp.xxxx.com",     "EnableSsl": true,     "UserName": "admin@xxxx.com",     "FromEmail": "admin@xxxxx.com",     "Password": "iNxxxx123",     "DefaultCredentials": false,     "Port": 123   }

After this we will add a class library project. In this class library we will add a new class file. We will make the added class file as static. Now add a function on which we will access the connection string in our class library.

But before writing the core we need to add the library reference of  Microsoft.Extensions.Configuration.Json and Microsoft.Extensions.Configuration.Binder. For this we will right click on project and click on manager nuget package.  Add search for  Microsoft.Extensions.Configuration.Json and Microsoft.Extensions.Configuration.Binder and install it.

Microsoft.Extensions.Configuration.Json

Microsoft.Extensions.Configuration.Binder

After this we will write code to class library to read the email of smtp setting present in appsetting.json in class library. 

using Microsoft.Extensions.Configuration; using System; using System.IO;  namespace ClassLibrary1 {     public static class Class1     {         public static void EmaiSettings()         {             var builder = new ConfigurationBuilder().SetBasePath(Directory.GetCurrentDirectory()).AddJsonFile("appsettings.json", optional: false);             IConfiguration config = builder.Build(); string host = config.GetValue<string>("Smtp:Host");             string username = config.GetValue<string>("Smtp:UserName");             string fromemailid = config.GetValue<string>("Smtp:FromEmail");             string password = config.GetValue<string>("Smtp:Password");             string defaultcredentials = config.GetValue<string>("Smtp:DefaultCredentials");             string port = config.GetValue<string>("Smtp:Port");             string enablessl = config.GetValue<string>("Smtp:EnableSsl");         }     } }

Now we have done run the application and check the output.
