How to set the isolation level for Entity Framework CodeFirst Migrations

Question

Answer 1

You can write and execute SQL in your migration code:

Before SQL Server 2012 use dynamic SQL:

public override void Up()
{
     Sql("DECLARE @SQL NVARCHAR(4000) = 'ALTER DATABASE '+ DB_NAME() +' SET ALLOW_SNAPSHOT_ISOLATION ON' ; EXEC sp_executeSql @SQL;", true);
}

For SQL Server 2012 or later:

public override void Up()
{
     Sql("ALTER DATABASE CURRENT SET ALLOW_SNAPSHOT_ISOLATION ON",true);
}

Change "ALLOW_SNAPSHOT_ISOLATION" to your isolation level.
