Hi,
I have some question about background uploader.
when I upload many files using background uploader and completion group, I found two issues.
please refer to below.
<issue 1 : Completion Group task does not work.>
- Test Case 1 : transfer 600 files.( file size : 108kb)
- Test Case 2 :
- Test Case Procedures :
1. after create uploader 1 and transfer group, send files.(200 files)
2. send files at same time(create uploader 2(200 files)).
3. send files at same time(create uploader 3(200 files)).
- Result : An InvalidOperation Exception has occurred when the background uploader are finished.
<issue 2 : Some files will not be sent..>
- Test Case : transfer 700 files.( file size : 108kb)
- Result : Some uploadoperation does not work( i think uploadoperation are missing)
I had sent files using reference to the MS samples(background transfer) .
<--------------
BackgroundTransferCompletionGroup completionGroup = new BackgroundTransferCompletionGroup();
BackgroundTaskBuilder builder = new BackgroundTaskBuilder();
builder.TaskEntryPoint = "Tasks.CompletionGroupTask";
builder.SetTrigger(completionGroup.Trigger);
BackgroundTaskRegistration taskRegistration = builder.Register();
BackgroundUploader uploader = new BackgroundUploader(completionGroup);
BackgroundTransferGroup transfer_group = BackgroundTransferGroup.CreateGroup("TestTrasferGroup_" + Count);
transfer_group.TransferBehavior = BackgroundTransferBehavior.Serialized;
uploader.TransferGroup = transfer_group;
foreach(var file in files)
{
UploadOperation upload = uploader.CreateUpload(uri, file);
Task<UploadOperation> startTask = upload.StartAsync().AsTask();
}
uploader.CompletionGroup.Enable();
------------------>
so, I would like to know about limitations of the background uploader .
1. Is there the maximun limitations of upload operation?
2. Is there possible concorrent transfer (via background uploader)?
Thank you,
JS
