fixing build for performance applications
Fixup references
Renamed Project.json to Project.json2
Fixed project.json casing
Added basic logging to migrations.
Also re-factored the code in Migrator to match the behavior from EF6 by running each migration in a separate transaction, instead of running all in one transaction. The UpdateDatabase code path is also used to generate SQL, with a "simulate" flag set to true, in which case the sql statements are collected but not executed.
Updated a bunch of tests and added more Migrator tests.
Clean-up of a few .csproj files.
Remove framework assembly versions
Fix inadvertent vertical tab in SqlServerConnectionTest
Commands: Use consistent method names
Commands: Add remaining "konsole" commands
