== Programming models ==

{{see also|ASP.NET Web Forms}}

ASP.NET supports a number of programming models for building web applications:<ref>{{cite web |title=Choose between ASP.NET and ASP.NET Core |archive-url=https://web.archive.org/web/20180509012506/https://docs.microsoft.com/en-us/aspnet/core/choose-aspnet-framework?view=aspnetcore-2.1 |websiteurl=https://docs.microsoft.com/en-us/aspnet/core/choose-aspnet-framework?view=aspnetcore-2.1|archive-date=2018-05-09|website=Microsoft Docs|url-status=dead| date=2018-03-14|language=en-us}}</ref>

* [[ASP.NET Web Forms]] – A framework for building modular pages out of components, with UI events being processed server-side. This framework is not included in the ASP.NET Core versions; it only works in the "classic" ASP.NET, on Windows.

* [[ASP.NET MVC]] – allows for building web pages using the [[model–view–controller]] design pattern.

* [[ASP.NET Web Pages]] – A lightweight syntax for adding dynamic code and data access directly inside HTML markup.<ref>{{cite web |title=ASP.NET Web Pages (Razor) FAQ |url=https://docs.microsoft.com/en-us/aspnet/web-pages/overview/getting-started/aspnet-web-pages-razor-faq#Whats_the_difference_between_ASP.NET_Web_Pages,_ASP.NET_Web_Forms,_and_ASP.NET_MVC |website=docs.microsoft.com |language=en-us}}</ref>

* [[ASP.NET Web API]] – A framework for building [[Web API]]s on top of the [[.NET Framework]].<ref>{{cite web |title=Get Started with ASP.NET Web API 2 (C#) |url=https://docs.microsoft.com/en-us/aspnet/web-api/overview/getting-started-with-aspnet-web-api/tutorial-your-first-web-api |website=docs.microsoft.com |date=30 September 2022 |language=en-us |first=Wasson |last=Mike }}</ref>

* [[ASP.NET WebHooks]] – Implements the [[Webhook]] pattern for subscribing to and publishing events via HTTP.

* [[SignalR]] – A real-time communications framework for bi-directional communication between client and server.

== IIS integrated pipeline ==

On [[Internet Information Services|IIS]]&nbsp;6.0 and lower, pages written using different versions of the ASP framework cannot share [[#Session state|session state]] without the use of third-party libraries. This does not apply to ASP.NET and ASP applications running side by side on IIS&nbsp;7. With IIS&nbsp;7.0, modules may be run in an integrated pipeline that allows modules written in any language to be executed for any request.<ref>{{cite web|url=http://learn.iis.net/page.aspx/244/how-to-take-advantage-of-the-iis7-integrated-pipeline|title=How to Take Advantage of the IIS 7.0 Integrated Pipeline|work=iis.net|date=14 June 2022|access-date=26 January 2009|archive-date=24 March 2010|archive-url=https://web.archive.org/web/20100324031657/http://learn.iis.net/page.aspx/244/how-to-take-advantage-of-the-iis7-integrated-pipeline|url-status=dead}}</ref>

** Developers are no longer forced to use Server.CreateObject(...), so early-binding and type safety are possible.

* Based on [[Microsoft Windows|Windows]] programming; the developer can make use of DLL class libraries and other features of the Web server to build more robust applications that do more than simply rendering HTML (e.g., [[exception handling]])
