I am building a .NET CORE RC2.0 app. I use Team Services to deploy to azure and the following guide: https://www.visualstudio.com/en-us/docs/build/apps/aspnet/aspnetcore-to-azure
"Builddefinition\drop\website.zip' is not in a supported .zip format and therefore cannot be read."
How can the .zip format not be supported when doing exactly like the guide?
