The update process takes an absurdly long time to complete each time I need to update my emdx from the database, rendering itself unresponsive as you click the finish (as finish the update) button.
I work with LocalDb SQL Server 2014 and Visual Studio 2015. To solve the problem, some individuals advised installing Service Pack 1. Although I installed LocalDb SP1, it did not make a difference. I very recently installed Visual Studio 2015, as well.
I have the most recent version of Entity Framework 6. (from nuget).
