Assignment #A5_ Ex2 Create and use a class library In this exercise, youll create a class library that includes the InvItem and InvItemDB classes of the Inventory Maintenance application from extra exercise 16-1. Then, youll use that class library with the Inventory Maintenance application. Create the Class Library project 7. Create a new Class Library project named InventoryLibrary in the Assignment5\Ex2_InventoryMaint_lib directory. 8. Delete the empty Class1.cs class, and add the InvItem and InvItemDB classes from the Inventory Maintenance project in the same directory. 9. Change the namespace in both of the classes you just added so its a namespace named Inventory nested within a namespace with your last name. 10. Change the solution configuration for the class library to Release, and then build the class library. When youre done, close the solution. Modify the Inventory Maintenance application to use the library 11. Open the InventoryMaintenance project in the Chapter 16\InventoryMaint With Library directory. 12. Delete the InvItem.cs and InvItemDB.cs files, and then add a reference to the InventoryLibrary assembly you created in step 4. 13. Display the code for the Inventory Maintenance form, and add a using directive for the namespace you created in step 3. Do the same for the New Item form. 14. Test the application to be sure it still works.
