How to use:
/// Migrations Options
public class DbMigrationsOptions
{
/// <summary>
/// Allow auto migration with data lost
///
</summary>
public bool AutomaticMigrationDataLossAllowed { get; set; } = false;
/// <summary>
/// Enable to execute auto migration
///
</summary>
public bool AutomaticMigrationsEnabled { get; set; } = true;
/// <summary>
/// Drop all tables from database and recreate based on model snapshot.
Useful in scenarios when the data is transient and can be dropped when the schema changes. For example during prototyping, in tests, or for local changes.
///
</summary>
public bool ResetDatabaseSchema { get; set; } = false;
/// <summary>
/// Allow to update snapshot.The key will pe replaced with value for each KeyValuePair
///
</summary>
public Dictionary<![CDATA[string, string]]> UpdateSnapshot { get; set; } = new Dictionary<![CDATA[string, string]]>;
}
Option 1 (using method):
MigrateDatabaseToLatestVersion.Execute(context);
MigrateDatabaseToLatestVersion.Execute(context, new DbMigrationsOptions { ResetDatabaseSchema = true });
Option 2 (using context extension)
context.MigrateToLatestVersion();
context.MigrateToLatestVersion(new DbMigrationsOptions { ResetDatabaseSchema = true });.
