Microsoft has just released.NET 6 Preview 3 just two days after releasing.NET 5.0.5. Microsoft refers to this version as a preview because it is still in the testing phase, and the company expects its subscribers to provide feedback so that it can improve the process before publishing a stable release.
If you’re running Windows 10 Version 1809 or higher, you’re probably running.NET Framework 4.8. Manual upgrades to.NET 6 Preview 3 are available via the links provided below. We do not recommend upgrading devices that are currently in a production/live environment because this release contains a few bugs.
.NET 6 Preview 3 includes new features and enhancements
This release focuses primarily on minor improvements and enhancements to.NET 6. Although these minor tweaks have a significant impact on overall performance for developers, many may be unaware of these changes.
This release is almost entirely focused on low-level performance features. These are the kinds of improvements that many people don’t always fully appreciate, but they make a big difference in a lot of apps.Microsoft Blog
The vast majority of the updates directly affect Common Language Runtime (CLR) systems, making the experience faster or more compatible with modern CPUs.
This release also includes several bug fixes for ASP.NET Core, as discussed in a separate blog post by Microsoft.
Let’s take a look at the highlights of this preview release.
Improved struct updating speed
Microsoft has added a new unsafe API called “CollectionsMarshal.GetValueRef” that allows users to update their struct values in Dictionaries faster than before. However, Microsoft states that this API is intended for scenarios requiring high performance and not for general use.
Refer to Microsoft’s official post for more information and a sample.
Check and cast quicker interface
The interface casting speed was successfully increased by 16 to 38 per cent by Microsoft. This has been accomplished with fewer arguments in a few modes and greater parallel access for the CPU port.
Moving parts of the.NET Runtime from C++ to C# allows more developers to participate in the feedback, as many of them learn about C# compared to C++.
.NET Hot Reload for web applications is now available
The.NET Hot Reload allows developers to apply code changes while running the app without restarting it. This feature is now available for web apps using dotnet watch as it is now available for offline applications.
The next 3 years after its release in November 2021 Microsoft plans to support.NET 6. This is included with the release of Long Term Support (LTS).
