CopyAsync
I'm getting a NotImplementedException whenever StorageFile.CopyAsync is called. Is this part of the API not finished yet? For reference, I'm using Visual Studio Professional 2015 with update 3 and Hololens OS version 10.0.14342.1016.

The following code for me executed with no exceptions:
create_task(Windows::Storage::StorageFolder::GetFolderFromPathAsync(Windows::ApplicationModel::Package::Current->InstalledLocation->Path + L"\\Assets\\Models")).then([this](Windows::Storage::StorageFolder^ folder) { auto fileTask = create_task(folder->GetFileAsync(L"gaze_cursor.cmo")).then([this, folder](Windows::Storage::StorageFile^ file) { auto copyTask = create_task(file->CopyAsync(folder, L"copy.cmo", Windows::Storage::NameCollisionOption::ReplaceExisting)); }); });Visual Studio Enterprise Update 3
OS Build 10.0.14342.1016
Firmware Rev: 0005.05.M.1604281147R
Deployed/debugged via USB
I forgot to specify that the exception is thrown when there is an existing file with the same name. The function works as expected on the other platforms we support. The code is:
await file.CopyAsync(existingFolder, newName, NameCollisionOption.ReplaceExisting);
Chris - I'm getting the same issue. CopyAsync throws a NotImplementedException if the file already exists. Did you ever find a solution for this? I'm using C++.
