Cannot add appsettings.json inside WPF project .net core 3.0
I am creating a WPF project using .net Core 3.00, and I am having trouble adding the item appsettings.json file to my project which is to be used to store my DB connection string.
I would normally have done inside the app.config, but this has now been removed from .net Core.
Everywhere mentions using appsettings.json as a replacement, and that it has to be maunally added & initialised in the OnStartUp() function using an instance of IConfiguration, and there after using Dependancy Injection to pass in the config class into the project.
But my issue is that can only add the appsettings.json item on asp.net Core projects?? not my WPF solution.
I do appolgies if I'm missing somthing very obvious (which I probally am), I just cant seem to find any solutions.
Many thanks in advance

Steps:
To Add the following nuget packages
Microsoft.Extensions.Configuration Microsoft.Extensions.Configuration.FileExtensions Microsoft.Extensions.Configuration.Json Microsoft.Extensions.DependencyInjectionYou would need to create and add appsettings.json manually and set
copy it to output directoryascopy if newer
AppSetting.json
{
"ConnectionStrings": {
"BloggingDatabase": "Server=(localdb)\\mssqllocaldb;Database=EFGetStarted.ConsoleApp.NewDb;Trusted_Connection=True;"
},
}
Program.cs (For .NetCore Console App)
static void Main(string[] args)
{
var builder = new ConfigurationBuilder()
.SetBasePath(Directory.GetCurrentDirectory())
.AddJsonFile("appsettings.json", optional: false, reloadOnChange: true);
IConfigurationRoot configuration = builder.Build();
Console.WriteLine(configuration.GetConnectionString("BloggingDatabase"));
}
App.xaml.cs (For .NET CORE WPF)
public partial class App : Application
{
public IServiceProvider ServiceProvider { get; private set; }
public IConfiguration Configuration { get; private set; }
protected override void OnStartup(StartupEventArgs e)
{
var builder = new ConfigurationBuilder()
.SetBasePath(Directory.GetCurrentDirectory())
.AddJsonFile("appsettings.json", optional: false, reloadOnChange: true);
Configuration = builder.Build();
Console.WriteLine(Configuration.GetConnectionString("BloggingDatabase"));
var serviceCollection = new ServiceCollection();
ConfigureServices(serviceCollection);
ServiceProvider = serviceCollection.BuildServiceProvider();
var mainWindow = ServiceProvider.GetRequiredService<MainWindow>();
mainWindow.Show();
}
private void ConfigureServices(IServiceCollection services)
{
// ...
services.AddTransient(typeof(MainWindow));
}
}
