How to save IFormFile to disk?

Question

I'm trying to save a file on disk using this piece of code.

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?

A few things have changed since core's release candidates

public class ProfileController : Controller {     private IWebHostEnvironment _hostingEnvironment;      public ProfileController(IWebHostEnvironment environment) {         _hostingEnvironment = environment;     }      [HttpPost]     public async Task<IActionResult> Upload(IList<IFormFile> files) {         string uploads = Path.Combine(_hostingEnvironment.WebRootPath, "uploads");         foreach (IFormFile file in files) {             if (file.Length > 0) {                 string filePath = Path.Combine(uploads, file.FileName);                 using (Stream fileStream = new FileStream(filePath, FileMode.Create)) {                     await file.CopyToAsync(fileStream);                 }             }         }         return View();     } }

There are to be further changes in Core 3.0 as IHostingEnvironment is now marked as obsolete.

using Microsoft.Extensions.Hosting;  public class ProfileController  : Controller {     private IHostEnvironment _hostingEnvironment;      public ProfileController(IHostEnvironment environment)     {         _hostingEnvironment = environment;     }
