Support

Since .NET 7 is the current release of .NET, it will receive free support and patches from Microsoft for the next 18 months.

In terms of operating systems, this release will be compatible with the following architectures on Red Hat Enterprise Linux (RHEL) version 8:

  • AMD x64
  • Intel x64
  • ARM (aarch64)
  • IBM Z
  • LinuxONE (s390x)

Native AOT

Ahead-Of-Time (AOT) is a technology that generates code at application build time, instead of run-time. Native AOT brings full native pre-compilation to .NET desktop client and server scenarios. Native AOT is not replacing these existing technologies, rather it’s offering a new set of capabilities that unlocks new form factors.

Native AOT is similar to .NET’s existing AOT technologies, but it produces only native artifacts. In fact, the Native AOT runtime does not know how to read the .NET assembly file formats – everything is platform-native.

Performance Improvements

Performance continues to be a major focus for .NET 7. Microsoft reimplemented the precode and call counting stubs (tiered compilation helper stubs) to significantly reduce the number of post-creation modifications of executable code in the runtime. This resulted in 10-15% startup time improvements.

This change also resulted in steady-state performance improvements (up to 8%) in some microbenchmarks and some ASPNet Benchmarks even without Write-Xor-Execute enabled.

Final Thoughts

As the name of this release indicates, it is still in the development phase. This is why we do not recommend that you install it in a production environment.

Moreover, Microsoft has suggested you use .NET 7 Preview 3 with preview versions of Visual Studio, which is also not recommended in live environments. Thus, it would be better to install and test out .NET 7 Preview 3 in a test environment or a Virtual Machine (VM).
