I am running Visual Studio 2013 Update 5, and i try to deploy to an Azure Web app (B1). I haveinstalled Sitefinity trial, running the 'default' project alright on on SQL Server 2014.
So far, i got "object not set to an instance of an object" in two different locations, and an addon Hang.
1) First, i had no Azure SDK installed, and by clicking "Deploying Sitefinity to Windows Azure", i got that. Then I installed SDK 2.7, and kept getting it.
Then i installed Win10, luckily i intended to do that before. And installed Azure SDK 2.6, and the above exception disappeared.
2) Then i clicked all check boxes in Thunder deploy UI (Set up SF project for Azure deployment etc...). As i already had a Azure SQL created, it asked me to override it, it started doing something, but an Timeout error occured at some time, and the addon was still in progress but i could not close it.
3) Then i deleted my SQL resource in Azure, rerun addon, it created the database and tables, then asked me to choose Azure subscription and import publish settings. NOTE: subscription dropdown is empty although i have logged in to my Azure Bispark subscription in VS. Anyway I browse for .publishsettings file , select it from a folder, and i get again "object not set to an instance of an object". If i do it again, without the database database migration, i get that exception again, and Visual Studio crashes.
So, so far a Thunderous experience with Sitefinity;)
