.NET Web Development, Week 10

Meeting Purpose

Introduce and implement doubly linked list data structure and its core operations.

Key Takeaways

• Doubly linked list nodes have both next and previous pointers, enabling bidirectional traversal
• Implemented isEmpty, size, insertAtHead, removeHead, and toArray
• Practiced explaining the 'why' behind code decisions, in preparation for ACE requirements

Meeting Purpose

Review full-stack CRUD application development in C# ASP.NET MVC, focusing on creating a book tracking application.

Key Takeaways

• Built the initial structure for a 'Bookshelf' app, including model, view, controller, and database
• Covered creating forms, handling submissions, and basic CRUD operations
• Emphasized data validation, model binding, and following MVC architecture patterns

Meeting Purpose

Complete the full CRUD functionality for a full-stack web application, focusing on read all, read one, update, and delete operations.

Key Takeaways

• Implemented read all, read one, update, and delete for a book entity using view models
• Incorporated form validation, data normalization, and CSRF protection
• Demonstrated the PRG (Post-Redirect-Get) pattern for the update and delete flows

Meeting Purpose

Review and implement doubly linked list methods in a coding class session.

Key Takeaways

• Implemented and tested insertAtTail, removeTail, and find
• Students demonstrated strong code explanation skills, articulating why each segment exists
• Resolved npm/TLS issues by removing package-lock.json and reinstalling

Meeting Purpose

Implement an authentication system for a .NET web application.

Key Takeaways

• Distinguished authentication (verifying identity) from authorization (granting permissions)
• Built a registration form with password hashing via BCrypt
• Created view models, controllers, and views for the registration flow

Meeting Purpose

Implement session-based authentication in an ASP.NET Core MVC application.

Key Takeaways

• Implemented registration, login, logout, and protected-page functionality using session state
• Demonstrated password hashing, input validation, and CSRF protection
• Explored conditional view rendering based on authentication status

Meeting Purpose

Review and implement doubly linked list algorithms: insert before and insert after.

Key Takeaways

• Implemented insertBefore() and insertAfter(), both with O(1) time complexity
• One group creatively reused insertBefore() within its insertAfter() implementation
• Emphasized defending code choices and explaining rationale

Meeting Purpose

Implement a one-to-many relationship between a User and a Blurb (post) model in a .NET MVC application called 'Blurb'.

Key Takeaways

• Created the Blurb model and set up the one-to-many relationship with navigation properties and a foreign key
• Built a PostController along with view models for the index and create views
• Resolved 404 errors and object reference exceptions through routing and model checks

Meeting Purpose

Introduce a 'blurb app' Twitter Lite clone and implement the ability to create posts.

Key Takeaways

• Implemented post creation with content normalization, validation, and route protection
• Compared projection-to-view-model versus eager loading for displaying the post list
• Debugged a 'method not allowed' error caused by a form submitting as GET instead of POST

Meeting Purpose

Review and discuss implementations of doubly-linked list methods: Remove and Reverse.

Key Takeaways

• Remove handled edge cases for head, tail, and single-node lists
• Reverse was implemented in place using a pointer-swapping technique
• Discussion covered variable scoping and a possible single-node optimization

Meeting Purpose

Implement a many-to-many relationship (likes feature) in a .NET MVC application and begin work on a post details view.

Key Takeaways

• Implemented like/unlike functionality for posts via a many-to-many relationship
• Created a Like model and updated User and Post models with navigation properties
• Began a post details view, encountering a bug to investigate further

Meeting Purpose

Finish the full CRUD, full-stack week and implement new features in the Blurb app, including asynchronous controllers and preparing for the upcoming assessment.

Key Takeaways

• Fixed a post-details bug by properly eager loading related data
• Created an async version of the PostController for improved performance
• Reviewed requirements for the upcoming 'Sign Up and Sign In' assessment-prep assignment
