On “How do I migrate a WPF project from framework 4.6.2 to Core 3?”
Edit: Here is the video from the release live stream: link to this video
During the live stream event, MS people specifically said update first to target at least 4.7.2.
Step 1. Upgrade the project to target at least 4.7.2.
Step 2. Fix any issues and verify that the app functions as expected in 4.7.2. E.g. run unit tests/integration tests/etc or go through each thing and click/edit/save/delete
Don’t do any major refactoring. If something breaks you don’t want to be in a situation where you’re not sure if the bug is in the framework retargeting or your refactor.
Step 3 upgrade to .NET Core 3. 0. Retest the app.
