ASP.NET Core 8

Create an ASP.NET Core 8 razor pages web app with dotnet new, build and run on kestrel, and enable https with a dev certificate.

Learn to map rest principles onto http requests and razor pages, using endpoints and methods like get, post, put, patch, delete, with json payloads and status codes.

Explore ASP.NET Core 8 Razor pages by building get and post forms, binding data with the page model and bind properties, and using hot reload and simple publish.

Discover how the MVC pattern powers ASP.NET Core apps: the model stores state and validation, the view renders HTML from the model, and the controller coordinates input.

Discover the first ASP.NET Core MVC example, learn how controllers, views, and models interact, the role of index actions, view results, and basic post handling.

Create a simple Person model, wire it to a Person controller and index view in an ASP.NET Core MVC app, and rely on automatic model binding from form data.

Discover how program.cs powers startup in ASP.NET Core with the web application builder and dependency injection. Learn how services, middleware, Kestrel hosting, and configuration (appsettings.json) initialize and run the app.

Learn dependency injection in ASP.NET Core 8 by wiring services with the DI container, using addTransient, addScoped, and addSingleton lifetimes for unit testing with mocks.

Understand how ASP.NET Core builds a request pipeline with middleware, using Use, Run, and Map to route, branch, and even short-circuit to deliver responses efficiently.

Understand how middleware execute in a strict order, with short-circuiting and prerequisites; implement a typical sequence—exception handling, static files, authentication, routing—and see how misordering breaks behavior.

learn to write and wire custom middleware in asp.net core by defining a class with a request delegate, implementing invoke, and using extensions to plug into the pipeline.

Explore how built-in and custom middlewares shape the ASP.NET Core request pipeline, including static files, directory browsing, default files, file server, and status code handling.

Explore how ASP.NET Core middlewares replace legacy HTTP modules and HTTP handlers, migrating begin request and end request lifecycle stages into a unified invoke pipeline.

Explore Razor views in MVC, learn cshtml syntax, and blend HTML with server-side C#, using the @ symbol and inline expressions for dynamic content.

Understand Razor directives such as using, model, and inherits to create typed views, custom Razor pages, and simple view injection, plus startup service registration for reusable ui components.

Master partial views in asp.net core 8 mvc to reuse components, compare partial and regular views, pass models, and render with async and ajax for modular layouts.

Learn how layout pages provide a common header, menu, and footer, use render body and render section to inject content, and drive dynamic layouts via viewstart.

Build reusable, independent view components that run asynchronously across views. These components support dependency injection and can render dynamic menus or login panels.

Explore how HTML helper methods produce dynamic HTML in MVC, bind form inputs to model properties, and render elements like links, forms, labels, text boxes, radio buttons, and dropdown lists.

Bind html helpers to view data, populate a select list from a courses collection, configure value and text fields, and set default selections via viewdata.

Bind html helpers to a model by creating an employee object, rendering a form, and posting to bind back in the controller, with dropdowns for departments and enum types.

Explore how ASP.NET Core 8 display and editor methods generate markup from data types, using display, editor, display for, and editor for to render booleans, strings, and emails.

Create display and editor template cshtml files (int32, email address, currency) in ASP.NET Core 8, use UI hints, and reuse employee templates for consistent rendering.

Reuse content in views with html helpers, partial views, and app_code helpers to render tables; bind to view data and models; create extension methods and configure namespaces for cross-view sharing.

Learn how tag helpers replace html helpers to generate server-side HTML in Razor views, with asp-for binding, built-in tag helpers, and managing tag helpers via add, remove, and prefixes.

Explore anchor and image tag helpers, learn how they convert server-side tags into client html, and apply asp-protocol, asp-route, asp-all-route-data, asp-page, and asp-append-version for dynamic urls and cache busting.

Learn to use the form tag helper with action, method, and anti-forgery tokens, and apply input and select tag helpers with asp-for and asp-items in ASP.NET Core 8.

Learn to create custom tag helpers in ASP.NET Core 8 to generate dynamic HTML output using the process method and HTML context, enabling reusable tags with kebab-case attributes.

Understand how html forms submit data to the server, including inputs, checkboxes, radios, selects, and file uploads, with rules on nesting, submit buttons, and enctype.

Explore how the default model binder maps form, route, query string, and headers to action method parameters, including primitives, complex and nested types, arrays, and collection types.

Learn to customize model binding with bind, bind required, and bind never attributes, using prefix and include to control fields from form, query, route, header, or body.

Explore remote validation that trips to the server to verify data like username availability. Implement custom validation attributes and IValidatableObject for multi-property server-side checks.

Develop a custom range validator attribute for ASP.NET Core 8 that enforces min and max values on server and client, generating jQuery validation rules and unobtrusive adapters.
