.NET 6 will be supported as a Long Term Support (LTS) release.

Preview features are disabled by default. They are not supported for use in production and may be removed in a future version. The new RequiresPreviewFeaturesAttribute is used to criticize the preview API, and the corresponding analyzer warns you if you using this preview API.

What is the difference between .NET 5 and .NET 6 features?

If you are well aware of .NET framework architecture, Microsoft introduces several timely updates periodically. There are several key differences between .NET 5 and .NET 6 in terms of features and functionality. Here are some of the main differences:

  1. Cross-platform support: While both .NET 5 and .NET 6 provide cross-platform compatibility, .NET 6 has stretched its reach even further, with support for Apple Silicon, ARM64-based Linux systems, and other platforms.
  2. Performance: .NET 6 improves on .NET 5, including quicker startup times, better rubbish collection, and increased just-in-time (JIT) compilation.

  3. Compatibility: .NET 6 is intended to be largely compatible with previous .NET versions, making it easy for developers to upgrade their current applications to the latest version.

While .NET 5 and .NET 6 share many similarities, .NET 6 offers a number of new features and enhancements that make it an even more powerful and flexible platform for modern application development.

.NET 6 is supported by Visual Studio 2022 and Visual Studio 2022 Mac.

C# 10 and templates

  • C # 10 includes innovations such as global usage guidelines, file-scoped namespace announcements, and record structures. For more information, see what’s new in C # 10.
  • In conjunction with that work, the .NET SDK project templates for C # have been updated to use some new language features:
    • async Main method
    • Top-level statements
    • Target-typed new expressions
    • Implicit global use directives
    • File-scoped namespaces
    • Nullable reference typesc# features
  • By adding these new language features to project templates, new code starts with enabled features. However, the existing code is not affected when you upgrade to .NET 6. For more information about these template changes, see the .NET SDK: C # Project Templates Modernization Blog post.

All these features would help you in software development or when you try to build your mobile app for your ongoing business.


  • .NET 6 includes a number of performance improvements. This section lists some improvements in filestream, profile-guided optimization, and AOT integration. For detailed information, see the performance improvement in the .NET 6 blog post.


  • IO.FileStream type has been overwritten for .NET 6 to provide better performance and reliability on Windows. Now, the filestream is never blocked when created for asynchronous I / O on Windows. For more information, see the file IO updates in the .NET 6 blog post.

Profile-guided optimization

  • Profile-guided optimization (PGO) is where the JIT compiler generates optimized code with respect to the most used types and code paths. .NET 6 introduces dynamic PGO. Dynamic PGO works hand-in-hand with tire compilation to further optimize code based on the additional instrumentation placed during tier 0. Dynamic PGO is disabled by default, but you can enable it with the DOTNET_TieredPGO environment variable. For more information, see JIT Performance Improvements.


  • .NET 6 is introducing Crossgen2, the successor of Crossgen, which has been removed. Crossgen and Crossgen2 are tools that provide forward-of-time (AOT) integration to improve the app’s startup time. Crossgen2 is written in C # instead of C ++, and can perform analysis and optimization that was not possible with previous versions. For more information, see the conversation about Crossgen2.

Arm64 support

  • The .NET 6 release includes support for macOS Arm64 (“Apple Silicon”) and Windows Arm64 operating systems, for both the original Arm64 execution and x64 emulation. Additionally, x64 and Arm64 .NET installers now install For more information, see macOS 11 for Arm64 and x64 and .NET support for Windows 11.
