To add to this a little bit. There is deeper host side integration for these applications and the VM’s are virtual address backed (the guest vm’s memory is represented as a process on the host), which adds more opportunities to free up physical memory. The windows sandbox architecture page covers some of this. https://learn.microsoft.com/en-us/windows/security/threat-protection/windows-sandbox/windows-sandbox-architecture https://learn.microsoft.com/en-us/windows/security/threat-pr... Also WSL2, if I recall correctly, has a relatively minimal base OS with a custom init binary. I would say if you’re looking to use Host Compute Service, your best option would be to look at the way https://github.com/microsoft/hcsshim https://github.com/microsoft/hcsshim initializes containers.
