minimal api DI magic

Why does the upper one work, but the lower one doesnt?

v1.MapGet("/lmao4", (HttpContext context) => // Executes and returns 4444.
{
    Console.WriteLine("4");
    return TypedResults.Ok("444");
});
v1.MapGet("/lmao3", GetAllTodos); // Executes, but doesnt return 333.

app.Run();

static async Task<IResult> GetAllTodos(HttpContext context)
{
    Console.WriteLine("3");
    return TypedResults.Ok("333");
}

v1.MapGet("/lmao4", (HttpContext context) => // Executes and returns 4444.
{
    Console.WriteLine("4");
    return TypedResults.Ok("444");
});
v1.MapGet("/lmao3", GetAllTodos); // Executes, but doesnt return 333.

app.Run();

static async Task<IResult> GetAllTodos(HttpContext context)
{
    Console.WriteLine("3");
    return TypedResults.Ok("333");
}

Adjusted my question.. pretty sure I just found a bug :thinkang: I can inject absolutely anything and do the pretty syntax anything but HttpContext IHttpContextAccessor works, [FromBody] works, random services work

Just add a cancellation token It's best practice anyways

MaskoeOP•9mo ago

yea I saw that its just pretty funny, i was making a minimal example sample to show someone how easy and simple aspnetcore is compared to the go example he showed me. And immediately I ran into some weird cryptic gotcha that I needed like 2 hours to solve and im a 5 year experience all in on c# and aspnetcore andy 😹 now i hav to add "dude just add this CancellationToken thing, that you dont use, to the function signature, BUT only if you actually use the HttpContext"
