EDennis.MigrationsExtensions

This package provides extensions to Microsoft.EntityFrameworkCore.Migrations.MigrationBuilder to support SQL Server Temporal tables and/or TestJson tables. NOTE: to use any of these extensions, you need to replace the SqlServerMigrationsSqlGenerator service with the MigrationsExtensionsSqlGenerator from this library. see Custom Migrations Operations.

When you add migrationBuilder.SaveMappings(); to the end of the Initial Migration's Up() method, the migrationBuilder saves table<->class mappings and column<->property mappings as SQL Server extended properties. These extended properties are useful when you need to determine class names and property names from the information schema. The EDennis.DataScaffolder Win Forms app will use these extended properties, when they are available.

When you add migrationBuilder.CreateMaintenanceProcedures(); to the beginning of the Initial Migration's Up() method, the migrationBuilder generates a "_" schema (if needed) and creates a number of helpful stored procedures and functions: (a) ResetIdentities, which ensures that the next value for each identity specification is the maximum of the Id associated with the identity spec; (b) ResetSequences, which is similar to ResetIdentities, but with sequences; (c) GetMappings, which returns all entity framework mappings generated by the SaveMappings operation; (d) MaxDateTime2, which returns the maximum datimetime2 value; (e) RightBefore, which gets the datetime2 value that is 100 nanoseconds before the provided datetime2 parameter; and (f) RightAfter, which gets the datetime2 value that is 100 nanoseconds after the provided datetime2 parameter. It is recommended to add migrationBuilder.DropMaintenanceProcedures(); to the end of the Initial Migration's Drop() method.

For any given entity that has SysStart (datetime2) and SysEnd (datetime2) properties, when you add modelBuilder.Entity<SomeClass>(e => { e.HasAnnotation("SystemVersioned", true); to OnModelCreating, a SQL Server Temporal Table and history table are automatically created. The history table has the same name as the temporal table but resides in a new schema suffixed by _history.

When you add migrationBuilder.CreateTestJsonTableSupport(); to the Initial Migration's Up() method, the migrationBuilder generates a "_maintenance" schema (if needed), creates a TestJson table, and creates a SaveTestJson stored procedure. It is recommended to add migrationBuilder.DropTestJsonTableSupport(); to the Initial Migration's Drop() method.
