DOTNET CONFIGURATION PART 1

In this first part of the series I will show you an approach I have used successfully in managing configurations and secrets when building .net core apps

Spin up Visual studio and create a .net 6 core console app.

Add some appsettings.json file for environment specific variables

Then add an Item group to the project file and paste the following to nest the appsettings files

 <ItemGroup>
    <Content Include="appsettings.json">
      <CopyToOutputDirectory>Always</CopyToOutputDirectory>
    </Content>
      <None Update="appsettings.Local.json">
        <DependentUpon>appsettings.json</DependentUpon>
        <CopyToOutputDirectory>Always</CopyToOutputDirectory>
      </None>
    <None Update="appsettings.Docker.json">
      <DependentUpon>appsettings.json</DependentUpon>
      <CopyToOutputDirectory>Always</CopyToOutputDirectory>
    </None>
  </ItemGroup>

Add the following variable to each of the files

appsettings.json -> "DemoUsername": "DefaultUserName"
appsettings.Docker.json -> "DemoUsername": "DockerUserName"
appsettings.Local.json -> "DemoUsername": "LocalUserName"

Open the properties of the project and navigate to Debug -> General -> Open debug launch profiles UI.

Add the following Environment Variable

DOTNET_ENVIRONMENT = Local

Close that UI and you should now have a properties folder with the launchSettings.json added.

Install the following Nuget packages

  • Microsoft.Extensions.Configuration
  • Microsoft.Extensions.Configuration.UserSecrets
  • Microsoft.Extensions.Hosting

Then Select the project -> Manage User Secrets

This should open the secrets.json file that is unique to you. Add a variable to this file

{
"SecretPassword": "HelloFromUserSecrets"
}

Paste the following code into the program.cs

using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using System.Reflection;

using IHost host = Host.CreateDefaultBuilder(args)
.ConfigureAppConfiguration((context, config) =>
{
var settings = config.Build();


    var environmentName = context.HostingEnvironment.EnvironmentName;
    var isLocalEnv = environmentName == &#34;Local&#34; || environmentName == &#34;Docker&#34;;

    if (isLocalEnv)
    {
        config.AddUserSecrets(Assembly.GetExecutingAssembly(), true);
    }
    else
    {
        //ToDo Add AZ App Configuraton
       
    }

})
.Build();

var config = host.Services.GetService<IConfiguration>();
Console.WriteLine("Username is - " + config.GetValue<string>("DemoUsername"));
Console.WriteLine("Password is - " + config.GetValue<string>("SecretPassword"));

Press F5 to run the project and you should see the variables printed out in the console window.
