WEBSYS FINALS

a free and open-source developer platform for building websites and applications

.NET

.NET is built on a high-performance runtime utilized by several high scale apps such as these 4:

microsoft teams

UPS mobile app

forza horizon

allegiance consulting

.NET CLI or an integrated development environment

.NET apps and libraries are built from a project file and a source code or using these 2:

.NET SDK

is one of the .NET binary distributions and is a set of tools, libraries, and runtimes for app development, building, and testing

.NET Runtimes

another binary distribution of .NET

This is considered the foundation of all .NET apps are built on.

common language runtime (CLR)

it uses a garbage collector for memory allocation and release because it enforces type and memory safety

why is .NET often called a “managed code” runtime?

these are the 3 .NET supported programming languages

C#

F#

visual basic

C#

a general purpose object and component oriented programminf language

F#

a programming language for writing compact, strong, and performant code. data-oriented, where code involves transforming data with functions

visual basic

event driven programming language that provides a GUI by simply dragging and dropping objects and modifying their codes

these are 3 versions of .NET that support different types of apps

.NET framework

mono

.NET core

.NET framework

a software development framework for building and running applications on windows for easy desktop and web application engineering. is the original .NET

mono

this provides complete SDK features to develop /NET applications on various platforms

a cross platform and open source implementation of .NET for the cloud age while remaining compatible with the .NET framework. used for linux, macOS, and windows apps

.NET core

ASP.NET

a framework developed and marketed by microsoft to allow programmers to build dynamic webpages that run on windows, linux, macOS, and docker.

active server pages

what does ASP stand for?

.aspx file extensions written in C#

what file extensions do ASP.NET pages have?

these 3 are added by ASP.NET to the .NET platform:

blazor

razor pages

authentication systems

blazor

allows the creation of interactive web UIs without writing JS

razor pages

a web page templating syntax to develop webpages by putting the server side C# logic in HTML

authentication systems

the third in the list of things that ASP .NET adds to the .NET framework. includes libraries, databases, and template pages for handling logins, including multifactor and external authentication requirements for online accounts

yes, and authoring libraries is possible if shared between applications on the .NET platform

does the diverse ecosystem of packages and libraries for .NET developers become available in regards to ASP .NET extending .NET?

ASP .NET offers 3 frameworks for creating web applications, each targeting a different development style:

web forms

ASP .NET MVC

ASP .NET web pages

web forms

an ASP .NET framework, building dynamic websites are possible using a drag and drop, event driven model. design surface and numerous controls allow rapidly built yet powerful UI driven sites with data access using rich controls with HTML markup encapsulation

an ASP .NET framework, a design pattern separating UI with business logic. includes features that enable fast, test driven development friendly features for creating apps.

ASP .NET MVC

over HTML markup, separated code and markup, and easy to write test

what does ASP .NET MVC have full control over?

for mobile and single page applications

ASP .NET MVC is best for what?

ASP .NET web page

an ASP .NET framework, a fast, approachable, and lightweight way to combine server code with HTML for dynamic web content like multimedia and social media embeds

no, it has them on the same file

do ASP .NET web pages have the HTML markup and codes in different files?

they are based on the .NET framework and share core functionalities of .NET and ASP .NET. they can also coexist in the same web app and are not entirely independent

what are the ASP .NET frameworks based on?

these are the 4 advantages of ASP .NET

web APIs

real time technologies

single page applications

mobile apps and sites

web APIs

an advantage of ASP .NET, a framework for building HTTP services that can be accessed using browsers and mobile devices

real time technologies

an advantage of ASP .NET, ASP.NET SIgnalR is a new library that makes developing real time web functionality easier

it allows bidirectional communication between the server and client browser by choosing the best method based on the capabilities of each

what does kind of communication does SignalR allow?

single page applications (SPA)

an advantage of ASP .NET, helps build applications with major client side interactions using HTML 5, CSS 3, and JS that load an HTML webpage and dynamically updates it as the user interacts with the app

mobile apps and sites

an advantage of ASP .NET, can power native mobile apps with a web API backend. same applies to mobile websites with responsive design frameworks

a cross platform, high performance, open source framework that runs on .NET core to build modern, cloud-enabled, and internet connected web apps, services, and mobile backends. can be developed and run on windows, macOS, and linux.

ASP .NET core

the new and enhanced version of ASP .NET with better functionality and libraries and a comfortable interface

what is ASP .NET core considered as?

ASP .NET 4.x

ASP .NET core is a repurposed version of ___ with changes resulting in a leaner and more modular framework

content root

this defaults to the project’s root directory during development

these 4 are included in the content root

the executable hosting the application (.exe)

compiled assemblies of the app (.dll)

content files used by the app, such as config files (.xml, .json), razor files (.razor, .cshtml), and data files (.db)

web root - path for resource files, such as images (.png, .jpg), stylesheets (.css), and javascript (.js) in a wwwroot folder

Program.cs

ASP .NET core aps created with web templates have the application startup code in the ___ where services required by the app are configured

host

an ASP .NET core app on startup build a ___ that encapsulates all of the app’s resources

a host in ASP .NET encapsulates all of the app’s resources, such as these 4:

logging

configuration

middleware

dependency injection (DI) services

logging

an API that works with various built in and party logging providers such as debug and azure app service

configuration

performed using one or more configuration provides such as azure key vault, environment variable, and key per line

middleware

software arranged into an app pipeline to control HTTP requests and responses

dependency injection (DI) services

makes configured services available throughout the app

these are the 3 different hosts capable of running an ASP .NET core app:

ASP .NET Core WebApplication or Minimal Host (used in all ASP .NET templates

.NET generic host integrated with ASP .NET core ConfigureWebHostDefaults

ASP .NET Core WebHost (avaiable only for backward compatibility)

yes, but only needs fewer callbacks to configure

does WebApplication behave similarly to the .NET generic host and expose several same interfaces?

these are the four benefits of ASP .NET Core

cloud ready

community-focused

crafted for testability

tooling that simplifies modern web development

ASP .NET Core has built-in features for handling errors that include these 4:

developer exception page

custom error page

status code page

startup exception handling

developer exception page

provides complete info about unhandled request exceptions, enabled by default when both ASP .NET Core apps run in the development environment (one of the execution environments available in ASP .NET Core)

custom error page

in this, UseExceptionHandler is called to configure a custom error handling page for the production environment (another execution environment in ASP .NET Core)

status code page

in this, UseStatusCodePages is used in the Program.cs as an ASP .NET Core app that does not provide a status code page for HTTP error status codes such as 404 - Not found

startup exception handling

in this, only the hosting layer can handle exceptions during app startup to capture startup and detailed errors
