1. Include the two above files in the root of your OrderDetailsMaintenance project.
2. Make sure to mark them as "Content" and "Copy Always" or "Copy if newer" in the properties
window of those two files.
3. Run the Scaffold-DbContext command to create a context class as well as a class to
encapsulate the Orders objects from the associated table in the mdf file. Make sure to include the
parameters for -Tables Customers (only worry about the attributes associated with the text boxes,
you don't need to worry about any other rows from the table)
4. Once you have ran the command, include an app.config file and add a connection string
element. Make sure to copy the connection string from your Context class to your app.config.
Then edit your context to grab the connection string from the app.config
(ConfigurationManager.ConnectionString["Northwind"].ConnectionString)
5. Code the Find button to Find the customer id and populate the details in the below text boxes.
1. If no order is found, display a message box.
6. Code the exit button
7. Code the Save button to update its attributes and call Update and SaveChanges() on that
particular entity.
1. Note: If you close the program, reopen it, and search for the entity you recently updated. You
may not see the changes depending on how you setup the mdf file in your project (because it
copies a new version to the bin directory each time you run the program). So, if you don't see
your changes, don't be alarmed.
