Business value: 

The Business Central server now runs on Microsoft .NET 6. This improves performance and resource consumption on all AL code execution.

Feature details:

  • Microsoft have moved the Business Central server to run on .NET 6 instead of .NET Framework 4.8.
  • Performance measurements suggest an improvement of 30 percent when executing AL code.
  • For on-premises installations, any existing .NET add-ins will need to be converted to .NET Standard before the Business Central environment can be upgraded to this release.
  • For more information, go to Migrating from .NET Framework to .NET Standard.
  • In the Microsoft base and system applications, all .NET add-ins have been converted to .NET Standard, except in the localized versions for the Netherlands and Mexico. In these versions, Microsoft encountered uses of .NET Framework where no .NET Standard options were available. The .NET add-ins in these two cases are hosted as Azure Functions. 

Who and What should Care?

If you are using on-prem and have not updated your source code from dotnet to external service like Azure function, then you need to start paying attention to those Custom .net to be upgraded/converted to .NET Standard 6.0.

If you are using on-premises solutions, refer to Microsoft source code to find out how it's done.


You can refer to fellow MVP Stefano Demiliani article, where he discussed about refactored custom .NET Assemblies.

Hope you learn and will be able to utilize this feature as Business Central 22 is available.
