cm.import.interop

We now officially target .NET Framework 4.8 assemblies for CM interop. As there are no version compatibility changes or behavioral changes, there should be no action required from your end. Note that Windows 10 and 11 has shipped with .NET Framework version 4.8 since 2019, and Microsoft officially has no plans to remove it as of September 2024.

We have also resolved an issue with COM interop type lookup when using certain system libraries like System.Net.Http.

Deprecation of Old UI

The old UI in CET is now deprecated and enters maintenance support period. This implies the following:

• New UI is now the default UX for all users.
• The toggle to switch over to old UI is now removed by default.
• No more feature / enchancements will be done for old UI.
• Only critical / blocking issues for old UI will be fixed.
• Issue will not be fixed if issue is not reproducible in new UI.
• Code for old UI persists until 17.0, and unused components will be deprecated moving forward.
