We are developing a server web API that is writing the excel directly to the output stream. But I just realized that we cannot write directly to the response output stream anyway (it is not seekable), so I had to create the excel file in a temporary memorystream and then copy that memory stream to the response stream, so there is no need for async when using this library...
