.NET 7: A Quick Overview of What’s New

NET7 is the latest version of Microsoft’s .NET Framework, which enables developers to build applications for the Windows operating system. NET7 includes enhancements to the CLR (Common Language Runtime) and the addition of the new Roslyn compiler. It also includes improvements to ASP.NET, WCF (Windows Communication Foundation), and WPF (Windows Presentation Foundation). In addition, NET7 introduces the new Windows Runtime, a cross-platform development platform that enables developers to create applications that can run on any device.

With .NET 7, developers will have the ability to build a wide range of applications including cloud, web, desktop, mobile, artificial intelligence, and IoT with just one SDK, one runtime, and one set of base libraries.

Let’s get into the nitty-gritty of how the new version of .Net will maximize your productivity.

Dot net 7 updates

What is the .Net 7 Framework?

Microsoft created and developed NET7, a multi-platform software development framework. NET7 is a platform for developing applications that run on Windows, Linux, macOS, and beyond. With .Net 7, developers can create applications and services for any platform and device.

.Net 7 is a Standard Term Support (STS) version that is supported for 18 months until May 2024. Besides, It includes an extensive library of classes, components, and libraries which provide the necessary foundation for any complex application.

Moreover, it is an advanced .NET Framework that helps developers to create high-quality, dynamic applications that don't rely on any single platform. It provides core development features and business logic building blocks that allow developers to build applications quickly and efficiently.

What’s New About .Net?

NET7 introduces several new features and functionality that make it easier for developers to create powerful applications. Unlike .NET 6, which was released in 2021 but was not fully unified and lacked some key components, .NET 7 will provide a seamless experience for developers, allowing them to use the same Base Class Library, compiler, and runtime to build their applications.

A major release in Microsoft’s journey towards .NET unification. This latest version comes with DotNet Core 7 Preview 1 and Entity Framework 7 Preview 1, offering enhanced support for cloud-native applications and containers.

Additionally, NET7 makes it easy to connect to different services and databases and provides an extensive set of common language infrastructure (CLI) tools to develop client-side and server-side applications.

Let’s have a look at some of the attributes that make .Net 7 unique:

New Language Features

NET 7 has various new language features that enhance the developer experience with C# 7.0. This includes the addition of expression trees and custom attributes, a faster Just-In-Time (JIT) compiler for optimized compiler assemblies, and updated APIs for building Windows Presentation Foundation (WPF) and Windows Communication Foundation (WCF) applications.

The Entity Framework in .NET 7 has also been improved, allowing for efficient and robust connections to data sources like SQL Server and Oracle. Other features include enhanced ASP.NET Core and containers, new cloud-native development tools, and the ability to create services using Microsoft Graph API. The deployment process in .NET 7 has also been redesigned, making it easier for developers to deploy their applications in the cloud without extra setup steps.

Performance Upgrade

.Net 7 introduces a significant improvement in application performance through runtime optimization, code execution optimization, dynamic scaling, and resource usage improvement. The .Net 7 JIT compiler ensures improved code execution time by reducing the time required for assembly compilation. Furthermore, the new runtime-aware memory manager reduces memory fragmentation and improves garbage collection performance. NET7 also enables native-code generation for supported language frameworks.

Improvements to System.Text.Json serialization

System.Text.Json serialization provides an improved way for serializing and deserializing data that is already present in .Net 7. With this feature, developers can serialize and deserialize objects to and from JSON format with less effort and fewer lines of code. This feature also provides faster serialization and deserialization performance than the previous method. Moreover, the System.Text.Json serialization provides better security and compliance with standards such as RFC 8259.

Cloud-Native Architecture

.Net 7 has added various enhancements aimed at supporting cloud-native architecture. As defined by the Cloud Native Computing Foundation, cloud-native technologies allow organizations to develop and run scalable applications in dynamic environments such as public, private, and hybrid clouds. NET7 supports building both serverless and cloud-native applications and includes cloud-oriented APIs and libraries to simplify the development of cloud-based applications and services. NET7 provides the necessary tools for building, deploying, and managing modern applications in cloud computing environments and is designed to be portable to various deployment environments such as public, private, or hybrid clouds .

Simplified Configuration

NET7 makes it much easier for developers to configure applications and services with simplified configuration options. The new features of .Net 7 includes improved configuration objects, better validation of configuration options, and a simpler API to use.

Better Containers

NET7 adds support for more containerization frameworks, such as Docker and Kubernetes, which enable developers to create applications and services that can be deployed in the cloud. Additionally, dotNET7 supports Windows containers, allowing developers to easily containerize .NET applications.

Enhanced .NET Upgraded Assistant

The .NET Upgraded Assistant of NET7 helps developers easily upgrade existing applications to the new NET7 framework. The assistant also provides assistance in converting existing applications to .NETStandard projects from.NETCore projects and guides developers in migrating from .NET Core Version 6.0 to 7.0.

.NET Multi-Platform App UI

NET7 includes the .NET Multi-Platform App UI, which provides developers with an easy-to-use development platform that can be used to build cross-platform applications. This UI framework supports Windows, macOS, iOS, Android, and Linux platforms, and provides developers with an integrated set of APIs and components to create consistent user experiences across multiple platforms.

Time to Upgrade Your Existing Projects to .NET 7?

NET7 provides new features to help developers upgrade their existing .NET projects to the latest version of the framework. The .NET Upgraded Assistant and .NET Designer will help developers to upgrade their existing projects to the .NET 7 framework. Additionally, .Net 7 provides detailed documentation and guidance to help developers migrate and upgrade their existing projects.

Furthermore, dotNET7 provides better support for the .NET Command Line Interface, allowing developers to easily use the command line for their applications.

Architecture Compatibility:

.Net 7 is backward compatible with .NET Core, .NET Standard, and .NET Framework, making it easier for developers to migrate their existing projects to the new platform.

Other StandOuts of .NET:

.Net 7 includes many additional enhancements such as improved ASP.NET Core, improved support for C# 8.0, and improved services and libraries.

Final Thoughts:

With features like dotnet-monitor, and the ability to containerize apps, the System.Threading.Channels library, rate limiting, and more, .NET 7 offers the latest in technology to developers.

If you're in the process of migration or planning to start, .NET 7 is the perfect place to begin. It provides a straightforward upgrade if you're on a .NET Core version and several compelling reasons to migrate if you're currently maintaining a .NET Framework version.

Moreover, Visual Studio 2022 17.4 is also available, and developing .NET 7 in Visual Studio 2022 gives developers best-in-class productivity tooling.

Stay tuned for the next Long-Term Support (LTS) version, .Net8, which is expected to be released in November 2023 and will focus on similar themes such as modern workloads, web APIs, and seamless cloud-native development.
