Visual Studio 2022 - scenarios 'Object reference not set to an instance of an object' When Accessing Configuration in a .NET 6 Web API
This might be a silly question, but I'm not sure how to approach I'm working with a frustrating scenario in my .NET 6 Web API project when trying to access configuration settings through `IConfiguration`... The application runs fine until I try to inject the configuration into my controller. The behavior I receive is: `Object reference not set to an instance of an object`. Here's a snippet of how I'm setting up my `Program.cs`: ```csharp var builder = WebApplication.CreateBuilder(args); builder.Services.AddControllers(); builder.Services.AddSingleton<IConfiguration>(builder.Configuration); var app = builder.Build(); app.UseAuthorization(); app.MapControllers(); app.Run(); ``` In my controller, I have: ```csharp public class MyController : ControllerBase { private readonly IConfiguration _configuration; public MyController(IConfiguration configuration) { _configuration = configuration; } [HttpGet("config-value")] public ActionResult<string> GetConfigValue() { var value = _configuration["MyConfigKey"]; return Ok(value); } } ``` I've double-checked that `MyConfigKey` exists in my `appsettings.json`: ```json { "MyConfigKey": "SomeValue" } ``` I also verified that `appsettings.json` is properly set to copy to the output directory. I've tried restarting Visual Studio, cleaning and rebuilding the solution, but the scenario continues. Is there something I'm missing in the configuration setup or injection? Any help would be greatly appreciated! Cheers for any assistance!
