Microsoft’s years-long initiative to integrate various development platforms with “just one .NET  going forward” has finally been completed by .NET 7, which was intended to happen in 2020.

Microsoft’s open source, cross-platform development platform, .NET 7, became available on Tuesday, 8 November 2022, the first day of the three-day .NET Conf online conference.

Your projects will run faster thanks to .NET 7’s new capabilities for C# 11/F# 7, .NET MAUI, ASP .NET Core/Blazor, Web APIs, WinForms, WPF, and other technologies. Additionally, .NET 7 makes it simple to containerize applications, implement CI/CD processes in GitHub activities, and achieve cloud-native observability.

We appreciate the many contributions from the open-source .NET community that shaped this .NET 7 release. 28k contributions were made during the Net 7 release by over 8900 contributors!

With a broad ecosystem of .NET packages with more than 330,000 packages, .NET continues to be one of the fastest, most popular, and most reliable platforms.

Microsoft Highlighted Four Key Elements:

• With the quickest version of .NET ever, performance advancements in .NET 7 allow developers to work quickly and effectively.
• With enhancements to .NET, MAUI improved support for .NET programs on ARM64 and a relationship with Canonical that integrates .NET with Ubuntu, .NET 7 further the platform’s unification path.
• With capabilities like built-in container support for the .NET SDK, Microsoft Orleans 7.0, and observability integrations, .NET 7 enables developers to quickly create modern, cloud-native apps.
• The developer experience has been streamlined by additions in C# 11 and F# 7, enabling developers to write less code and do more.

The Major .NET 7 Themes Were Further Described In The Announcement:

Unified

• One BCL
• New TFMs
• Native support for ARM64
• Enhanced .NET support on Linux

Modern

• Ongoing development of performance
• Improvements to developer productivity, such as container-first workflows
• Create cross-platform desktop and mobile applications using the same codebase.

.Net Is For Cloud-Native Apps

• Developing and deploying distributed cloud native apps is simple.

Simple

• With C# 11, create code that is simpler and shorter.
• Improvements to HTTP/3 and basic APIs for cloud-native applications

Performance

• Many performance improvements

Microsoft Emphasized What Is New, In Particular, .NET 7 Components, Such As C#, Libraries, And The SDK:

C# 11:

The most recent version of C#, C# 11, is currently accessible in .NET 7. We openly create and develop C#. To view the most recent C# feature requests and meeting notes, Once development is scheduled, you can check on its status on our Feature Status page. The following resources will help you learn more about C# 11:

• An early peek at C# 11 features
• Updates to the C# 11 Preview include UTF-8, raw string literals, and more.
• Generic math, necessary members, and more in the C# 11 preview
• What’s new in C# 11

Libraries:

The .NET libraries are always getting better. New APIs with entirely new features are frequently added. Existing APIs receive performance upgrades, which will help you if you upgrade.

These blogs cover a lot of .NET library improvements, but don’t overlook these deep library dives as well:

• Generic Math is one of the .NET 6 preview features.
• .NET 7 Preview 5 — Generic Math
• Regular Expression Improvements in .NET 7
• Announcing Rate Limiting for .NET

SDK:

Every new version of .NET brings a wealth of enhancements to the .NET SDK, which contains the essential tools for designing, developing, and maintaining .NET projects. 

Numerous improvements were previously present in earlier preview blogs, which you may read up on. Visit the following to learn more about new SDK features:

• Announcing built-in support for containers in the .NET SDK
• Introducing Central Package Management

Final Words:

Aside from .NET MAUI (Multi-platform App UI), Windows Forms, Windows Presentation Foundation, and the Orleans 7 framework for developing distributed applications.

.NET 7 is being released along with ASP .NET Core 7 and Entity Framework Core 7. In contrast, .NET 7 enhances the WebAssembly debugging experience and supports the processing of location change events for the Blazor web apps development tool.

.NET MAUI, which made its debut in September, outraged several developers who thought the technology needed more time to be ready. However, according to Scott Hunter, Microsoft’s VP of product for the Azure developer experience, the company has subsequently improved .NET MAUI.

Microsoft is releasing the Visual Studio 2022 17.4 IDE along with .NET 7. The IDE now has 64-bit capabilities thanks to Visual Studio 2022. 

.NET 7 experienced extensive preview and release candidate phases before this production release. Similar themes, including modern workloads, web APIs, and more fluid cloud-native development, are anticipated for .NET 8, which is expected to launch in a year.
