How Do I Access Configuration in ASP.NET Core 6 ?

Accessing Configuration in ASP.NET Core 6 and Beyond

Prior to ASP.NET Core 6, developers accessed configuration settings via the Startup.cs class, utilizing IConfiguration and IHostEnvironment. However, with the introduction of .NET 6 and Visual Studio 2022, Startup.cs is no longer used.

The modern approach leverages the WebApplicationBuilder returned by WebApplication.CreateBuilder(args). This builder provides direct access to both the Configuration and Environment properties:

<code class="language-csharp">var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
...
IConfiguration configuration = builder.Configuration;
IWebHostEnvironment environment = builder.Environment;</code>

Alternatively, you can access these properties from the WebApplication object, obtained after building the builder:

<code class="language-csharp">var app = builder.Build();
IConfiguration configuration = app.Configuration;
IWebHostEnvironment environment = app.Environment;</code>

This streamlined access allows seamless configuration of services and middleware. For instance, retrieving a database connection string from appsettings.json for use with a DbContext is straightforward:

<code class="language-csharp">builder.Services.AddDbContext<FestifyContext>(opt =>
{
    opt.UseSqlServer(configuration.GetConnectionString("Festify"));
});</code>

For comprehensive details and further examples on configuration access within .NET 6 and subsequent versions, refer to the official .NET migration guide and provided code samples.
