ASP.NET Core Web API upload and download file

问题

My scenario:

• ASP.NET Core 2.1
• Web API Controller
• Azure Blob Storage as storage

I read some docs on internet (and on Stack Overflow in particular), but I didn't find a real complete answer to my question.

Question

Which is the best practice to upload and download BIG files using a ASP.NET Core 2.1 Web Api Controller and Azure Blob Storage as back-end for saving data?

Please, suppose the controller is:

[Route("api/[controller]")]
[ApiController]
public class UploadDownloadController : Controller
{
    [HttpGet("upload")]
    public void Download()
    {
        ...
    }

    [HttpPost]
    public Result Upload([FromBody] string someData)
    {
        ...
    }
}

Where Result is a class to return some data on the operation.

Please note that:

• For BIG files, it's better not to use IFormFile interface
• Files can be very big: tens or hundreds giga

Thank you,

Attilio
