Autorename for existing files on upload does not rename .NET

Question

Here is the piece of code which is supposed to rename an existing file and upload it to Dropbox. It simply does nothing. What am I missing here?

using (var memFile = new FileStream(srcFile, FileMode.Open, FileAccess.Read))
{
var uploadFile= await dbx.Files.UploadAsync("/myfolder/" + fileName, WriteMode.Add.Instance, body: memFile, autorename: true);
}

Any help would be appreciated.

Are you uploading the same data again? If the data is exactly the same as what already exists at the destination path, no conflict will occur and it won't create a renamed copy.
