I have a base type that I want to inherit from, for all my DAO objects, but this member gets the error further down about not being defined:

type BaseDAO() =
    member v.ExecNonQuery2(conn)(sqlStr) =
        let comm = new MySqlCommand(sqlStr, conn, CommandTimeout = 10)
        comm.ExecuteNonQuery |> ignore
        comm.Dispose |> ignore

I inherit in this type:

type CreateDatabase() =
    inherit BaseDAO() 

    member private self.createDatabase(conn) =
        self.ExecNonQuery2 conn "DROP DATABASE IF EXISTS restaurant"

This is what I see when my script runs in the interactive shell:

C:\Users\jblack\Documents\Visual Studio 2010\Projects\RestaurantService\RestaurantDAO\CreateDatabase.fs(56,14): error FS0039: The field, constructor or member 'ExecNonQuery2' is not defined

I am curious what I am doing wrong.

I have tried not inheriting, and just instantiating the BaseDAO type in the function, but I get the same error.

I started on this path because I had a property that had the same error, so it seems there may be a problem with how I am defining my BaseDAO type, but it compiles with no error, which further confuses me about this problem.
