f# keyword use and using

I am trying to use System.Data.Sqlite with F#. In C#, I have code like

 using (DbTransaction dbTrans = con.BeginTransaction()) {
     using (SQLiteCommand cmd = con.CreateCommand()) {
         //blahblah
     }
     dbTrans.Commit();
 }

But in F#, when I use the similiar two using above I got error of the type bool is not compatible with the type IDisposable... EDIT I am really sorry for my question. use would work in F# case. I just dont know how to close/delete my quesetions.
