DbMigrator - verbose code-first migration

问题:

When using Package Manager Console, you can run the following command:

PM> Update-Database -Verbose

The -Verbose switch will write all attempted SQL commands to the console window, which is quite useful for debugging.

You can use the DbMigrator class to do the same in code:

Configuration config = new Configuration();
//... (set up the config object)
DbMigrator migrator = new DbMigrator(config);
migrator.Update();

Is there something like the -Verbose switch if you use the DbMigrator class? I looked all over the documentation, but couldn't find anything.

See if this article solves your problem:

In short:

MigratorScriptingDecorator scripter = new MigratorScriptingDecorator(migrator);
string script = scripter.ScriptUpdate(null, null);
