Hi everyone,
I know this is not a Revit API specific question, but I only find way too specific answers on SO, which do not apply to my case.
So I have a Solution which targets multiple Revit API versions. After upgrading the project to SDK style, and adding support for Revit 2025 (.NET 8), the 'hot reload' button in Visual Studio 2022 is not working anymore, although it worked perfectly before the upgrade.
Anyone else having this issue? Always having to restart the application really slows down my debugging workflow... Any help is appreciated!
Below some screenshots of my setup:

And relevant snippets of my .csproj file
