I did a fresh install of developer studio 2017 and tried to create a cross platform project only to be hit by one problem after another.
first it could not compile because of initializedComponent and some weird context thingy. I unloaded the project, look inside and reloaded and that problem disappeared.
next I try to open the designer only to get a message "Custom controls disabled. There was an internal issue with the rendering process".
ok.. I have had enough..... this is not ready for the market.
Unable to migrate preview core projects
Yet another editor bug
