ASP.NET Core 7: advanced patterns with IOptions Configuration for Complex Nested Objects
Hey everyone, I'm running into an issue that's driving me crazy. I'm working on a project and hit a roadblock. I've been struggling with this for a few days now and could really use some help... I'm relatively new to this, so bear with me... I'm currently working on an ASP.NET Core 7 application that utilizes IOptions for configuration settings. I've defined a complex nested structure for my configuration like this: ```csharp public class AppSettings { public DatabaseSettings Database { get; set; } public LoggingSettings Logging { get; set; } } public class DatabaseSettings { public string ConnectionString { get; set; } public int CommandTimeout { get; set; } } public class LoggingSettings { public bool LogToFile { get; set; } public string LogLevel { get; set; } } ``` In my `Program.cs`, I register the configuration like this: ```csharp var builder = WebApplication.CreateBuilder(args); builder.Services.Configure<AppSettings>(builder.Configuration.GetSection("AppSettings")); ``` When I try to access the options in my controller like this: ```csharp public class MyController : ControllerBase { private readonly AppSettings _settings; public MyController(IOptions<AppSettings> options) { _settings = options.Value; } public IActionResult GetDatabaseInfo() { return Ok(_settings.Database.ConnectionString); } } ``` I am receiving a `System.NullReferenceException` indicating that the `Database` property is null. I've checked my `appsettings.json`, and it looks like this: ```json { "AppSettings": { "Database": { "ConnectionString": "Server=myServer;Database=myDb;", "CommandTimeout": 30 }, "Logging": { "LogToFile": true, "LogLevel": "Debug" } } } ``` I've ensured that the section names match, and even tried reloading the configuration by calling `builder.Configuration.Reload();`, but it hasn't resolved the scenario. The `Logging` settings are being populated correctly, but the `Database` settings are always null. I also tried accessing the options through a simple console application and they worked fine. Could there be something specific to ASP.NET Core that is causing this behavior? Any insights or suggestions on what could be going wrong would be greatly appreciated. This is part of a larger application I'm building. Any help would be greatly appreciated! Am I missing something obvious? This is for a service running on Windows 10. I'm using C# 3.10 in this project. I appreciate any insights!
