Lite.Migrator is a tiny cross-platform SQLite migration framework for .NET applications. This library was built for speed and flexibility so you can quickly stand-up and reliably deliver scalable database solutions.

Use it with your container app or mobile development (.NET MAUI 🐒, Avalonia, Uno, etc.) projects.

Lite.Migrator takes a "migrate-up" approach. In most app deployments, we usually move forward and rarely downgrade (consider app stores). This helps keep the library small and nimble. Previously known as, SQLite.Migrator.

Detailed instructions can be found on the Using Lite.Migrator wiki page.

1. Add Lite.Migrator project to your solution
2. Create a folder in your solution to hold the scripts
3. Add SQL files as Embedded Resources
   • You must use the naming convention, "YYYYMMDDhhmm-FileName.sql"
4. Wire-up the controller

  // 1. Add a few `.sql` files as Embedded Resources to project
  //    in the namespace `MyProject.Namespace.Scripts`
  // 2. Execute the migrates as follows
  //    This will create the DB in your MAUI app's AppData directory.
  var dbPath = Path.Combine(FileSystem.AppDataDirectory, "Lite.Migrator.db3");
  var scriptNamespace = "MyProject.Namespace.Scripts";

  using var migrator = new Migrator(dbPath, scriptNamespace);

  // Install migration scripts
  bool isSuccessful = await migrator.MigrateUpAsync();

  var dbPath = Path.Combine(FileSystem.AppDataDirectory, "Lite.Migrator.db3");
  var scriptNamespace = "MyProject.Namespace.Scripts";

  using var migrator = new Migrator(dbPath, scriptNamespace);

  // List of all embedded script files
  var embeddedMigrations = migrator.Migrations.GetSortedMigrations();

  // List of scripts installed
  var installed = await migrator.GetInstalledMigrationsAsync();

  // List of scripts waiting to be installed
  var notInstalled = await migrator.GetMissingMigrationsAsync();

  // Install migration scripts
  bool isSuccessful = await migrator.MigrateUpAsync();

public async Task InstallMigrationsAsync()
{
  // Your EXE/DLL with the scripts
  var dbPath = @"C:\TEMP\MyDatabase.db3";
  var migsNamespace = "MyProjNamespace.Scripts";

  var migrator = new Migrator(dbPath, migsNamespace);
  bool = success = await migrator.MigrateUpAsync();

  // Required after v0.6
  migrator.Dispose();
}
