Examine cqrs, separating command and query responsibilities with command and query handlers that write to and read from specialized data stores, guided by a mediator that decouples controller from handlers.
Create an asp.net core mvc web app in Visual Studio 2022 using dotnet 8 for an online voting project, and configure csproj with nullable, implicit usings, and cqrs pattern integration.
Structure an ASP.NET 8 CQRS project by dividing it into four layers—domain, infrastructure (repository), application, and presentation—and add class library projects while outlining domain models and use cases.
Explore an ASP.NET 8 CQRS pattern built on clean architecture, detailing UI, application, domain, and infrastructure layers with command and query handlers for an online voting system.
Define the voter entity in the domain layer by extending identity user and adding full name, date of birth, state, city, address, has voted, and is authorized.
Define a vote entity in a file with vote ID, user ID, group ID, and date time, plus navigation properties. Outline creating a vote group class next for CQRS voting.
Define a vote group entity with id, name, description, symbol, and word count, link it to votes in a one-to-many relationship, scaffold a data context for real-time voting with cqrs.
Create a voting data context by inheriting identity db context, reference domain application user, and configure group and vote with one-to-many relations and foreign keys in OnModelCreating.
Configure a sql server connection string in appsettings.json and register it in program.cs, install the entity framework core sql server package, and migrate to create voting tables in the database.
Define a generic repository in the domain layer for the online voting system, with IRepository<T> providing async CRUD operations, filter expressions, ordering, includable properties, and disable tracking.
Define and organize the repository layer by creating empty interface files for group, vote, user, and unit of work, wiring them to the existing ward group and application layer.
implement repository patterns in the infrastructure layer by creating generic repositories tied to a voting context and db sets, enabling CRUD operations via dependency injection.
Implement the unit of work pattern with a voting context and repositories, enable async save changes and disposal, and register the unit of work for dependency injection in program.cs.
Organize the application layer with command and query folders, implement a register user command using mediator, and extend the application user with email and password, returning a boolean on submit.
Create a register user command handler that uses user manager to register an application user with profile data, assigns a role, and returns success or failure in a CQRS setup.
Create a login user command and handler that validate credentials using user manager and sign-in manager, with email, password, and remember me, returning a boolean on success.
Implement the logout user command and handler in the asp.net 8 cqrs real time voting project, using the sign in manager to sign out and return unit.
Implement the update voter authorization command and its handler using a user manager to fetch a user by id, set the is authorized flag, and persist changes.
Create a word group command and handler in an asp.net 8 cqrs real-time voting project, wiring a unit of work to add group with name, description, image url, returning bool.
Implement an update vote group command and handler in a CQRS pattern, using a unit of work to fetch the group by id and update name, description, and image URL.
Delete word group command and its handler, using a unit of work to fetch by id, delete when found, and return success.
Implement a cast vote command and handler inside a CQRS pattern, validate the user, create a vote entry with group and user IDs, and update the vote group count.
Create and validate register and login view models in the application layer for the ASP.NET 8 CQRS pattern, applying required field validations, password rules, and confirm password.
Create a get vote groups query and its handler using CQRS. Use a unit of work to fetch all vote groups and return IEnumerable<VoteGroup>, wiring via dependency injection.
Implement the get vote group by id query and its handler using a unit of work to retrieve a single vote group by id, paving the way for controller integration.
Create an ASP.NET 8 account controller with register get and post using mediator for CQRS, include anti-forgery token, validation, and redirect on success.
Master the login flow in ASP.NET 8 CQRS with real-time voting, handling get/post login, return URL, model state validation, login commands via mediator, and secure logout.
Generate and scaffold register and login views for the account controller using razor views and register/login view models, then build and fix errors, and configure the mediator in program.cs.
Create a role initializer to add a default admin and roles using user and role managers, then create the admin user and assign admin and water roles.
Configure identity services with application user and identity role, EF store, and token providers; register mediator and cookies, then add a role initializer pipeline to create admin and user.
Run the voting project with F5 or the green run button, then start the castle server and verify admin and voter roles in the Udemy online voting database tables.
Showcases implementing a login partial in the navigation bar to enforce voter and admin authentication via sign in manager and user manager, including is authorized handling.
Create a water view model in the application layer with user id, email, full name, is authorized, and is lockout; display name for authorized and wire into queries.
Create get all voters query and handler to fetch users in voter role via user manager, convert them to voter view models, and expose through the UI project's waters controller.
ASP. NET 8 Complete Guide with Clean Architecture and CQRS pattern. In complete tutorial i am using scratched based project that named is Online Voting System.
Online Voting Project have many modules like you can enter political party details , vote counts , authentication and authorization and layered based project.
Students learn lots of thing about clean architecture and CQRS pattern, how to divide project responsiblity in diffrent clean architecture layer.
Student start this project from scratch. I mean start it from Domain Layer where we have some entiies and use cases of the project. This is simple class library.
Project. Next start from Infrastructure layer , where we have EFCore code to communicate with Database. In complete code i use EFCore model first approach.
Next layer start with Application layer , where we start Queries and QueryHandlers also Command and Command handlers.
Now with the help of MVC web Project ,we can communicate with Application layer and you can say complete project.
I use identity for authication and authorization. In this project we have two role , one is admin and other is voter.
Students learn lots of things from this course
-- How CQRS Works , How to Design Layers for Real time project. How layers are communicate to each others
-- How to design layers according to Clean Architecture.
