If you’ve already worked with frameworks like Express.js before, this concept isn’t new to you. It refers to an architectural style where web services receive and send data from and to client apps. The goal of these applications is to centralize data that different client apps will use.

Apart from the above features and libraries, .NET includes other APIs and Model to improve and enhance the .NET framework. Following is the .NET framework Stack that shows the modules and components of the Framework. Vendor lock-in – While some technologies like .NET Core(including .NET 5+), Xamarin, etc. are open sources, a major portion of the .NET ecosystem is still very much proprietary to Microsoft. Moreover, it will be difficult to switch to a different vendor in the future. The _operationFinished field is a SendOrPostCallback delegate that represents a callback method that we want to execute when a message dispatches to a synchronization context.

Entity Framework

A local resource is explicit to a specific page, which is the one in particular who can get to it, while global resources can be accessed from any place. Local resources are kept in the App_LocalResources organizer, while global are kept in the App_GlobalResources folder. Local and global resources records will appear to be identical, so the only distinction is the folder they reside in.

It’s the responsibility of the filter to choose when and where to execute the endpoint it is filtering. Deciding when to run the next argument gives you the same flexibility you’d have with middleware, as filters behave very similarly. While a RequestDelegate has a single parameter, as you’ll see later, we can pass any number of arguments to our endpoint definitions using dependency injection. ASP.NET API is an API application model (Application Programming Interface). Classic ASP pages have the file extension .asp and are normally written in VBScript.

What is the Model in MVC 5

General purpose programming languages such as C# and VB are the mainstays of modern development. Yet the idea of model-driven development (MDD), where software creation depends at least in part on some kind of underlying abstract model, is a hot idea in the industry today. Visual Studio 2005 reflects this in its support for what are known as domain specific languages (DSLs). In general, a DSL might be expressed in text, graphically, or in some other way.

The Web applications use HTTP to build up correspondence between the Web program and the Web server. The RedirectPermanent(String) method overload gives a 301 HTTP status code in the reaction and incorporates asp.net programming model the URL to divert the request. It shows that a lasting redirection exists, and it gives the redirection area. Once we created a single copy of this control, we can use this copy to different projects as well.

Asynchronous Programming Model (APM)

For instance, if we want to build modern, fast, and scalable cloud applications, .NET provides a rich set of Azure SDKs and APIs. If we are looking to build web apps, ASP.NET Core and Blazor are excellent choices. On the other hand, .NET MAUI is a great platform for building both desktop and mobile apps. Xamarin is a great choice for native mobile app development whereas Unity is the go-to choice for game development.

Yet different applications have different communication requirements. To meet these diverse needs, the .NET Framework class library includes three distinct technologies for creating distributed applications. Many more namespaces are defined, providing support for file access, serializing an object’s state, remote access to objects, and much more. In fact, the biggest task facing developers who wish to build on the .NET Framework is learning to use the many services that the library provides. There’s no requirement to learn everything, however, so a developer is free to focus on only those things relevant to his or her world. Still, some parts will be relevant to almost everybody, and so the next sections provide a quick overview of some of this large library’s most important aspects.

As the name implies, in a single-page application (SPA) there’s only one HTML page which is downloaded from the web server when the user opens the page. Any further interaction with that page will not directly result in a request to the web server. Instead, it will be handled by the JavaScript code which will update the existing page accordingly. It runs on top of the .NET framework (with no support for .NET Core) and is not actively developed anymore. Applications written in ASP.NET MVC must be hosted in IIS on Windows.

• For example, a program may get information from the student records or accessing employee records, etc.
• It is a most important software framework from Microsoft, it always continues to rocks the information technology.
• Most new Windows applications created today are built wholly in managed code, but it can also be useful to extend pre-.NET applications with managed code.
• It was also mandatory to use Microsoft’s Internet Information Services (IIS) web server.

JavaScript code will then process the data received and update the existing page. Such an application will only run in IIS (Internet Information Services web server) on Windows and will not be as performant as .NET Core hosted applications. Also, the upcoming ASP.NET Core 3.0 will run only on .NET Core and won’t support the .NET framework anymore. Each building block type has its own folder in the project structure. ASP.NET Core is a great framework to use when creating web applications. It comes with many useful APIs you can use to build clean, maintainable applications.

Common language runtime (CLR)

The configuration of these lines internally configures our database context for dependency injection using a scoped lifetime. We say that a category has many products, and we set the properties that will map this relationship (Products, from Category class, and Category, from Product class). The initial code is basically identical to the code of the service interface. Let’s create a repository that will be responsible for intermediating the database communication as a way to persist categories. I personally like it, because it keeps applications easy to read, even if you’re new to a company that uses .NET technology. A namespace consists of a group of related classes, interfaces, enums, and structs.

The browser submits a web form to the web server and the server returns a full markup page or HTML page in response. Filters are a mainstay of ASP.NET Core MVC and can help reduce commonly-repeated code. Recently introduced in .NET 7, the addition of Minimal API filters aims to do the same as their predecessor. Let’s modify our code to add a timestamp filter to hydrate the current date and time to the Hugged response objects.

Universal Windows Platform (UWP)

It attaches one, more power to the C# or .NET languages to generate a query for any LINQ compatible data source. You can also use LINQ with SQL, with XML files, with ADO.NET, with web services, and with any other database. There are also some other technology like Java, PHP, Perl, Ruby on Rails, etc. which can be used to develop web applications. The web applications which are developed using the .NET framework or its subsets required to execute under the Microsoft Internet Information Services(IIS) on the server side.
