TestSupportSchema

This is a TEMPERARY project (it will move into EfCore.TestSupport when EF Core 5 is released) to contain the code that wipes the database schema and replaces it with a database that matches the current EF Core classes/configuration.

Why is this useful?

When you are writing your unit tests you are likely to use the command context.Database.EnsureCreated() to set up the database you use for unit testing. That works for Sqlite in-memory databases, but it you are using a real database, then you need to call below to make sure that the database schema is up to date

context.Database.EnsureDeleted();
context.Database.EnsureCreated();

The problem is the EnsureDeleted/EnsureCreated calls take a LONG time. This feature has the same effect (e.g. correct schema, empty of data) but is MUCH quicker e.g. for a very small database the timings are:

What	First use	Second use
EnsureDeleted/EnsureCreated	10 secs.	10 secs.
EnsureClean	300 ms	30 ms
Respawn (see note below)	170 ms	35 ms

NOTE: Respawn is a NuGet library that removes all the rows in all the tables in a database. Useful if you have already called EnsureClean on the database and just want to remove the rows.*
