Windows 10 1903 (and Business Central Containers)

Some weeks ago, I read about Windows 10 1903 in a blog post from Mike Fortin here: https://blogs.windows.com/windowsexperience/2019/04/04/improving-the-windows-10-update-experience-with-control-quality-and-transparency.

  • Why do I have the Assert Codeunit twice?
  • Why can’t Business Central find the Assert Codeunit?

Just to name a few.

This blog post will try to explain how symbols works and give an answer these questions, by showing some samples. Continue reading

Process Isolation for containers in Windows 10

For a few months we have known that Docker for Windows would get support for process isolation under Windows 10. Arend-Jan Kauffmann explained how to use nightly builds from Docker to get the feature early and test it. I of course jumped on this and have been running a nightly build of Docker since December 6th.

A few days ago the feature was released in the edge release of Docker Desktop. Continue reading
