Last month, I had the privilege to deliver a session on SharePointDSC along with dozens of my colleagues. The conference was an unprecedented success. The keynote and the first set of Microsoft sessions were all recorded and broadcasted live. The recording for these sessions is available Here, but requires you to register first.
As far as the content for the other session goes, all the decks and demos used are available to the public on Snapboard at:
The SharePoint Conference 2019 has also been announced and will be back for another year at the MGM Grand Hotel in May of 2019. The link to the event is available Here
