ASP.NET Cheat Sheets

ASP.NET is documented here as three separate lineages — ASP.NET Web Forms, ASP.NET MVC (Razor), and ASP.NET Core (Blazor) — each with its own runtime, package set, and support status. This page spans more than one lineage; see each sub-section’s own landing page for its specific version and support-status disclaimer.

This content was generated with the assistance of AI and should be verified against the official documentation linked throughout before being relied on in production.

This section’s bibliography lists the reference material consulted while preparing these pages.

This section’s three lineages each get their own one-page, printable cheat sheet — pick the one that matches what you’re actually working in.

Lineage What’s on it Download

Lineage	What’s on it	Download
ASP.NET Web Forms	`.aspx` skeleton and directives, the page life-cycle event order, postback/ViewState essentials, the server- control catalogue, validation controls, a master page + `ContentPlaceHolder`, a `GridView` `SqlDataSource`/`ObjectDataSource` snippet, `Eval`/`Bind`, the state-management table, `@OutputCache`, `global.asax` events, `IHttpHandler`/`IHttpModule` skeletons, a Forms-auth `web.config` block, and `ScriptManager` + `UpdatePanel`.

ASP.NET MVC (Razor)	`Global.asax` + `App_Start` layout, a controller with the main `ActionResult` types, conventional and attribute routes, Razor syntax essentials, layout/section/partial, the strongly typed HTML-helper set, a validated view model with DataAnnotations + `ModelState`, the four filter kinds and their order, `BundleConfig`, a Web API 2 `ApiController` + `WebApiConfig`, the OWIN `Startup` + Identity 2 registration, `@Html.AntiForgeryToken()` + `[ValidateAntiForgeryToken]`, and an EF6 migration command block.	Download PDF
ASP.NET Core (Blazor)	The `dotnet` CLI, a minimal `Program.cs`, the middleware order, DI lifetimes, the Options pattern, a `MapGroup` CRUD with `TypedResults` + endpoint filter and built-in validation, a controller action, Razor Page `PageModel`, Tag Helpers, a Blazor component with `@rendermode`, `EditForm` and `[PersistentState]`, a SignalR hub, `AddDbContext` with an async LINQ query and a migration command, auth + policy, `UseExceptionHandler` + `AddProblemDetails`, output caching + rate limiting + `HybridCache`, a `WebApplicationFactory<Program>` integration-test skeleton, and `dotnet publish` + Dockerfile.
