HTTP requests processed by IIS go through a series of states on the way to generating a response. Similarly, ASP.NET pages also go through a series of states. As with IIS, the runtime generates events at each state that you can register a handler for and take action on. This diagram of the standard synchronous page life cycle and associated events.
The HTTP request enters the page-processing pipeline at the top of the figure when IIS starts to execute the Page Handler. As the processing progresses, the runtime moves from one state to another, calling all registered event handlers as it goes. In the synchronous case, a single thread from the ASP.NET thread pool does all the processing for the page.
The Render phase is not an event. All pages and controls have a Render() method that’s responsible for generating the output that will be sent to the client.
For Init and Unload, the runtime fires the events for child controls before the parent, so the Page events fire last. For Load and PreRender, the runtime fires events in the parent followed by child events, so Page events fire first. The other events in the figure above, except for Control Events, only exist at the Page level, not in controls. The runtime treats master pages as child controls of the Page.
DataBind is an optional event that happens after PreRender either when you set a DataSourceID declaratively, or when you call DataBind(). Read more dot net course
If you have code blocks in your markup (using <%= %>), the runtime executes that code during the Render phase. That’s why you can’t set control properties using code blocks; controls are instantiated, including setting their initial properties, at the beginning of the page life cycle, whereas Render happens at the end.
Instead of the usual serial and synchronous approach, it’s possible to configure a page to run asynchronously. For asynchronous pages, ASP.NET inserts a special “async point” into the page life cycle, after the PreRender event. One thread executes the part of the life cycle before the async point and starts the async requests. Then the same thread, or possibly a different one from the thread pool, execute the rest of the life cycle after the async point.

One of the reasons ASP.NET Core is faster is its extensive use of asynchronous patterns within the new MVC and Kestrel frameworks.3.Multiple environments and development mode ASP.NET Core introduces improved support for controlling application behavior across multiple environments, such as development, staging, and production.
Environment variables are used to indicate which environment the application is running in, allowing the app to be configured appropriately.4.Dependency Injection ASP.NET Core is designed from scratch to support Dependency Injection.
ASP.NET Core injects objects of dependency classes through constructor or method by using built-in IoC container.5.Swagger OpenAPI Swagger is a set of open-source tools built around the OpenAPI Specification that can help you design, build, document and consume REST APIs.
Its use allows developers to document and develop APIs while maintaining synchronization with the code.What is ASP .NET Core?ASP.NET Core is an open source and cloud-optimized web framework from Microsoft.
It includes the MVC framework, which now combines the features of MVC and Web API into a single web programming framework.Why use ASP .NET Core?The features of ASP .Net Core are listed below: Supports Multiple Platform:ASP.NET Core applications can run on Windows, Linux, and Mac.
using Bower (a package manager for the web).
ASP.NET is a much-needed boon for the startups to solve all there jitters in the beginning and help them to run smoothly for a more extended period.

Dot web may be a software package framework. it's developed by Microsoft. Dot web primarily runs on Microsoft Windows. it's free on thirteen Feb 2002. Its current version is four.7.2.Dot web have a massive library. It conjointly provides language interoperability. Inter-operability refers to the capability of 2 completely different languages to act with the same arrangement. Here you'll study options and edges in Dot web. you'll conjointly learn additional concerning Dot web in Dot net Online Training Hyderabad.
Important options in Dot web
Easy development of new application
Dot web uses for developing applications. we are able to deploy in Windows, UNIX operating system and waterproof in operating systems. Asp.Net may be a technology accessible in Dot web Platform. By mistreatment this technology you'll build dynamic and data-driven Applications. Microsoft Azure helps for deploying any applications. ASP Dot web Provides advanced interface parts. it'll facilitate to avoid wasting to write down tons of cryptography.
OOPS Support
OOPS, stand s for Object-Oriented artificial language. Dot web provides a completely Object homeward-bound setting. therefore developers will write the code simple and easy. options and edges In Dot web
Multi-Language support
One of the most advantage in DOT web is Multi-Language support. If you have got skills in C++ you'll Mould to Dot web. Currently, there square measure four languages in Dot web. they're Visual Basic.Net, C#, JScript web and Managed C++. several vendors square measure engaged in developing alternative languages. even supposing the syntax is completely different for languages, however, they will simply Mould to Dot web. options and edges In Dot web
Automatic Memory Management
While developing applications developers need to concentrate on resources like memory.
Memory discharge is that the main reason for the failure of any applications. the good advantage in Dot web is memory handling is on its own. the rubbish collector can pay attention to releasing unused objects. options and edges In Dot web
This can be done at acceptable intervals.
Asynchronous via async/await
ASP Dot web supports for utilizing Asynchronous programming patterns. it's enforced altogether. web framework categories & third party libraries. Most of the application developers pay longer for information queries. They conjointly spend on central processor cycles, net service calls etc.
There is the reason for selecting ASP Dot web.ASP Dot web is quicker attributable to its Asynchronous patterns. And with its New MVC and Kestrel Frameworks. Features and edges In Dot web
Unified MVC and net API Frame Works
Before ASP DOT web, Developers uses solely MVC and net API frameworks. MVC stands for model read controller. MVC uses for making net applications to serve hypertext mark-up language. net API uses for making reposeful services mistreatment JSON.
With ASP DOT web, MVC and net API are unified along. And MVC also can come JSON information rather than hypertext mark-up language. This simplifies Development for developers in Dot web.
Multiple Environments & Development Mode
One of the simplest options is that the New setting feature. It permits you to differentiate components of your code simply.
Self Hosted net Applications
Sometimes you would like associate application which will deploy the solely in the desktop. therefore it's potential by mistreatment ASP Dot web Profiler, Prefix. thence Its face is all hypertext mark-up language and of hundreds ASP.Net Application within the window. Another feature in Dot web is net application is actually a console application.
Action Filters
Dot web is that the support for protrusible filters. Filters in Dot web use for error handling and authorization method.
Security
Dot web Platforms square measure safe and secure for enterprise applications. so, a number of the options square measure kind safety, code access security and role-based authentication. These build Dot web Applications additional strong and secure.
Conclusion
ASP Dot web may be a Nice upgrade. during this post, a number of the options square measure highlighted .make attentive to these options. And you'll conjointly learn additional on Dot web in .net Online Course Hyderabad
