[Visual C++] Intellisense bug with create_async by Simon FERQUEL

I found a bug in the VC11 IntelliSense when mixing tasks and IAsyncOperations<T>^. Here is the code snippet that produce an IntelliSense error (but compile / run successfully):

IAsyncOperation<FileReadWriteProxy^>^ FileReadWriteProxy::FromFile(IStorageFile^ file, uint64 contentSize, uint64 alreadyWrittenLength, uint32 readBufferSize, Platform::String^ identity)
{
    task<FileReadWriteProxy^> task = create_task(file->OpenAsync(FileAccessMode::ReadWrite))
        .then([=](IRandomAccessStream^ fileStream)
    {

        return ref new FileReadWriteProxy(file, fileStream, contentSize, alreadyWrittenLength, readBufferSize, identity);
    });
    IAsyncOperation<FileReadWriteProxy^>^ asyncOp = create_async([=]{return task;});
    return asyncOp;
}


The error refers to the line "IAsyncOperation<FileReadWriteProxy^>^ asyncOp = create_async([=]{return task;});".
