Hi everyone,
We have completed our analysis of NServiceBus compatibility with .NET 11 Preview 4 and wanted to share the results with you.
TL;DR: Solutions that currently work well on .NET 10 should continue to work as expected on .NET 11.
What we’ve done
Here’s what we did to verify our compatibility with .NET 11:
- We ran our suite of automated tests in the NServiceBus repository after changing them to target .NET 11.
- We ran a hand-picked selection of samples to test a variety of components.
Although we haven’t yet run all the tests for all of our component libraries against .NET 11, we believe the tests we ran provide reasonable proof of .NET 11 compatibility without unreasonable cost.
What to look for
As we get closer to Microsoft’s November 2026 launch date for .NET 11, we will continue to re-run our tests when each preview is released. If we find anything of concern, we’ll update this post. Otherwise, “no news is good news.”
As soon as the final version of .NET 11 is released, we’ll begin the effort of running all the automated tests for all of our component libraries.
Is there a specific aspect of .NET 11 that concerns you, or a new language feature you’d like to see supported in a future version of NServiceBus? Feel free to let us know in this thread, or send us a support case, and we’ll be happy to help.
With thanks,
The team in Particular
