问题
We take bacpacs of our Azure V12 database every night and restore locally using the command
C:\Program Files (x86)\Microsoft SQL Server\120\DAC\bin>.\SqlPackage.exe /a:Import /sf:C:\1.bacpac /tdn:db1 /tsn:server1
As of 8 Nov 2016, this command has started failing with :
*** Error importing database:Could not read schema model header information from package. The model version '3.5' is not supported.
This looks similar to a previous problem we had with this process back in April SQL Azure V12 BACPAC import error: “The internal target platform type SqlAzureV12DatabaseSchemaProvider does not support schema file version '3.3'”
That time is was due to a scoped configuration option of maxdop. This time it appears to be another new configuration option which has just appeared (from the model.xml):
<Property Name="TemporalHistoryRetentionEnabled" Value="False" />
Why has this property seemingly randomly appeared in the model.xml ?

I ran into the same issue. There is a new data tier applications framework.
It took me a few hours to find it.......

I installed it and my imports from bacpac files with sqlpackage.exe work again.
Hope that helps!
ps. I am on a 64 bit machine and had to install both the 32 and 64 bit framework upgrade.
