How can I read the appsettings.json in a .Net 6 console application?

April 21, 2022

I try to create a .Net 6 Console Application but having troubles reading my appsettings.json file. In a web application I could use this…

var builder = WebApplication.CreateBuilder(args);

But what would I use in a console application? I get this error when trying to add it to program.cs. "The name 'WebApplication' does not exist in the current context"

>Solution :

Add these two nuget packages in your application

Microsoft.Extensions.Configuration

Microsoft.Extensions.Configuration.Json

Then you can use ConfigurationBuilder to use appsettings.json file

var configuration =  new ConfigurationBuilder()
     .SetBasePath(Directory.GetCurrentDirectory())
     .AddJsonFile($"appsettings.json");
            
var config = configuration.Build();
var connectionString = config["ConnectionString"];
