Explanation:

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

The Main() method is the entry point for the program. In the Main() method, 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 insert a record into the "employee" table using ExecuteNonQuery() method of MySqlCommand class and then print the "Record inserted successfully" message on the console screen.
