How to save IFormFile to disk with efficenient method ?

IHostingEnvironment _hostingEnvironment;
public ProfileController(IHostingEnvironment hostingEnvironment)
{
_hostingEnvironment = hostingEnvironment;
}

[HttpPost]
public async Task<IActionResult> Upload(IList<IFormFile> files)
{
foreach (var file in files)
{
var fileName = ContentDispositionHeaderValue
.Parse(file.ContentDisposition)
.FileName
.Trim('"');

var filePath = _hostingEnvironment.WebRootPath + "\\wwwroot\\" + fileName;
await file.SaveAsAsync(filePath);
}
return View();
}

I was able to replace IApplicationEnvironment with IHostingEnvironment, and ApplicationBasePath with WebRootPath.

It seems like IFormFile doesn’t have SaveAsAsync() anymore. How do I save file to disk then?
