How to inject IConfiguration in asp.net core 6

Question

There is no Startup.cs in the web/api application any more.

We used to be able to inject IConfiguration into that Startup class.

public class Startup
{
    public Startup(IConfiguration configuration)
    {
        Configuration = configuration
    }
    ...
}

Now that those add service and configuration code is moved into Program.cs, what is the correct way to access configuration from there?

Answer 1

The IConfiguration can be accessed in the WebApplicationBuilder.

So no need to inject IConfiguration any more, it is now a property in the builder in Program.cs.

var builder = WebApplication.CreateBuilder(args);
var config = builder.Configuration;

builder.Services.AddInfrastructureServices(config);
builder.Services.AddPersistenceServices(config);
