What are the benefits of choosing ASP.NET Core over ASP.NET?
ASP.NET Core is a high-performance, cross-platform, and open-source framework. It allows you to build modern, cloud-enabled, and Internet-connected apps.With ASP.NET Core, you can:Build web applications and services, Internet of Things (IoT) apps, and backends for mobile applications.Work on your favorite operating system such as Windows, macOS, or Linux, and choose the tools and IDEs of your choice.Develop on and Deploy to the cloud or on-premises.Take advantage of containers and Docker to ease the deployment and distribution of your application.Run on the modern, fast, lightweight .NET Core framework.Some of the significant benefits of the ASP.NET Core framework over the ASP.NET framework ...
Read MoreExplain how logging works in ASP.NET Core
Logging is the process of recording events in software as they happen in real-time, along with other information such as the infrastructure details, time taken to execute, etc. Logging is an essential part of any software application. Having logs is crucial, especially when things go wrong. Logs help you understand the failures or performance bottlenecks and fix the problems.Logs are typically written to a database, console, or file, depending on the severity of the application and convenience. Although it's possible to record any data in the logs, you write informational messages and error messages in general. The informational messages capture ...
Read MoreExplain the role of HttpContext class in ASP.NET Core
The HttpContext encapsulates all the HTTP-specific information about a single HTTP request.When an HTTP request arrives at the server, the server processes the request and builds an HttpContext object. This object represents the request which your application code can use to create the response.The HttpContext object constructed by the ASP.NET Core web server acts as a container for a single request. It stores the request and response information, such as the properties of request, request-related services, and any data to/from the request or errors, if there are any.ASP.NET Core applications access the HTTPContext through the IHttpContextAccessor interface. The HttpContextAccessor class ...
Read MoreHow does ASP.NET Core provide data access with Entity Framework?
Entity Framework is an ORM (object-relational mapper) framework that makes it easy to create, retrieve, update, or delete data from relational databases. Using Entity Framework, you can work with C# objects that abstract the database related code, so you rarely have to deal with raw SQL.The following figure illustrates where the Entity Framework fits into a layered architecture.Entity Framework Core (EF Core) is the new version of Entity Framework 6. Similar to .NET Core, EF Core is a lightweight, open-source, and cross-platform version of Entity Framework. It is developed to be used with .NET Core applications.To integrate EF Core into ...
Read MoreHow to create a Dialog in JavaFX?
A Dialog is a graphical element, a window that shows information to the window and receives a response. You can create a dialog by instantiating the javafx.scene.control.Dialog class.ExampleThe following Example demonstrates the creation of a Dialog.import javafx.application.Application; import javafx.geometry.Insets; import javafx.scene.Group; import javafx.scene.Scene; import javafx.scene.control.Button; import javafx.scene.control.ButtonBar.ButtonData; import javafx.scene.control.ButtonType; import javafx.scene.control.Dialog; import javafx.scene.layout.HBox; import javafx.stage.Stage; import javafx.scene.paint.Color; import javafx.scene.text.Font; import javafx.scene.text.FontPosture; import javafx.scene.text.FontWeight; import javafx.scene.text.Text; public class DialogExample extends Application { @Override public void start(Stage stage) { //Creating a dialog Dialog dialog ...
Read MoreNull Aware Operators in Dart Programming
Dart has different null aware operators that we can use to make sure that we are not accessing the null values and to deal with them in a subtle way.Mainly, these are −?? operator??= operator? operatorWe will go through each of them in the following article.?? operatorThe ?? operator returns the first expression if and only if it is not null.ExampleConsider the example shown below −void main() { var age; age = age ?? 23; print(age); var name = "mukul"; name = name ?? "suruchi"; print(name); }In the above example, we declared two ...
Read MoreImmutability in Dart Programming
Immutability is the ability to remain constant. Whenever we talk about immutability we mention the immutable nature.In object oriented and functional programming, we make use of the immutable nature of objects a lot. Being immutable means that the state of the object cannot be modified after its creation.It is a very important topic these days when we talk about front-end development, as there are several occasions and scenarios where we want to maintain the state and the way to do that is to make use of immutability.In Dart, there are different ways with which we can achieve immutability and sometimes ...
Read MoreFuture class in Dart Programming
There are different classes and keywords in Dart which we can use when we want to run Asynchronous code. The future class allows us to run asynchronous code and we can also avoid the callback hell with the help of it. A future mainly represents the result of an asynchronous operation.In Dart, there are many standards library calls that return a future, some of them are −http.getSharedPreference.getInstance()A future in Dart can have two states, these are −Completed - When the operation of the future finishes and the future complete with a value or with an error.Uncompleted - When a function is called, and it ...
Read MoreComments in Rust Programming
Comments in Rust are statements that are ignored by both the rust compiler and interpreter. They are mainly used for human understanding of the code.Generally, in programming, we write comments to explain the working of different functions or variables or methods to whosoever is reading our code.Comments enhance the code readability, especially when the identifiers in the code are not named properly.In Rust, there are multiple ways in which we can declare comments. Mainly these are −Single-line commentsMulti-line commentsDoc commentsIn this article, we will explore all the three comments.Single-Line commentSingle line comments in Rust are comments that extend up to ...
Read MoreExplain the iterator pattern in .NET
The iterator pattern is used to loop over the elements in a collection and is implemented using the IEnumerator interface. It defines the basic low-level protocol through which elements in a collection are traversed—or enumerated. This is done in a forward-only manner.Here's the IEnumerator interface in C#.public interface IEnumerator{ bool MoveNext(); object Current { get; } void Reset(); }MoveNext advances the current element or "cursor" to the next position, returning false if there are no more elements in the collection.Current returns the element at the current position (usually cast from object to a more specific type). MoveNext ...
