Publish Reports Directly to the Service with Power BI Desktop

Currently Power BI Desktop works with PBIX files saved to a local file system only. The files can be uploaded or published directly by the Desktop.

Saving to the file on the file system in many cases may be unnecessary, and in some cases even counterproductive. Power BI Desktop should be able to publish directly to the Power BI service without having to first save a file locally. It should also be able to open and edit reports (and data models) directly from the service.

This behaviour would be consistent with Power BI Report Builder.
