C# , Issue with writing HTTP content into FileStream, Cannot access a closed file

I am trying to write HTTP content into a FileStream, and I get the error of "Cannot access a close file" at line where I do await CopytoAsync(stream). If I remove the "await", it will continue the operation without any exception, however the written file size is 0KB. Any Idea where I am committing the mistake ? 

   var provider = new MultipartFormDataStreamProvider(tempdir);
     await Request.Content.ReadAsMultipartAsync(provider);
            foreach (var content in provider.Contents)
    {
         using (var stream = new FileStream(serverPath, FileMode.Create, FileAccess.ReadWrite))
                {
                    await content.CopyToAsync(stream);
                }
    }

I solved the issue, by using the FileData property instead of Content in MultipartFormDataStreamProvider.

Also, I am not using the CopyToAsync anymore, instead I am using the normal File.Move and it works for me perfectly.

  var provider = new MultipartFormDataStreamProvider(tempdir);
  await Request.Content.ReadAsMultipartAsync(provider);
        foreach (var content in provider.FileData)
          {
                File.Move(content.LocalFileName, serverPath);
          }
