FromFormAttribute is in wrong namespace.

[lbgitjp]

var builder = WebApplication.CreateSlimBuilder(args);
var app = builder.Build();

app.MapPost("/UploadFiles", async ([FromForm] IFormFile myFile) =>
{
    string tempfile = Path.GetTempFileName();
    await using var stream = File.OpenWrite(tempfile);
    await myFile.CopyToAsync(stream);
});

app.Run();

in above code, if i use [FromForm], i need add below namespace:

using Microsoft.AspNetCore.Mvc;

but i don't use any Mvc features, so the class Microsoft.AspNetCore.Mvc.FromFormAttribute( [FromForm]) is in wrong namespace,

thanks!

This is an historical artifact - the team are aware of it, but moving it would be a hugely breaking change.

If you wish to avoid using the attribute entirely because of its presence in the MVC namespace, then you can implement your own using IFromFormMetadata like this which should work the same in a Minimal API.

I see, thanks!
