    End Sub
End Module

Press any key to continue . . .

Explanation

In the above program, we imported a namespace MySql.Data.MySqlClient to establish the connection with the MySql database. Then we created a module Module1 that contains a Main() function.

The Main() function is the entry point for the program. In the Main() function, we created a connection string variable ConnString that contains the database connectivity credentials. After that we established the connection to the MySql database using MySqlConnection class and then drop the "employee" table in the database using ExecuteNonQuery() method of MySqlCommand class and print the "Table employee dropped successfully" message on the console screen.
