  4. Step 4: Insert the connection string code

    In the Code Editor window, insert the following code into the <configuration> section:

    <connectionStrings>
  <add name="ConnectionString" 
       connectionString="Data Source=SERVER_IP;Initial Catalog=DBname;User Id=DBuser;Password=DBuser_password;" 
       providerName="System.Data.SqlClient" />
</connectionStrings>

    Replace SERVER_IP, DBname, DBuser, and DBuser_password with your actual database server IP, database name, username, and password.

  5. Step 5: Save the file

    After making the changes, click the Save button to apply the configuration.
