I'm having an odd problem wich I haven't been able to find a solution for. Suddenly I am not able to select a Target or Source in Schema Compare in VS2017. When I click the Combobox nothing happens. It is still possible to do a Data Compare and SQL Queries.
I've updated SSDT to version 15.5.1 but with no succes. VS is version 15.5.2
I was able to make this work using the arrow keys. A workaround, but definitely malfunctioning drop downs. See also here
