service 'Sdl.Desktop.platform.CommandBars.IActionService' could not be started after migrating Plugin to .Net Framework 4.7.2

Due to the upgrade to the .net Framework of one of the reference we used in the plugins (to 4.7.2), we needed to migrate the plugin to this framework too.

The build is ok, and the plugin is generated. But on the launch of the Studio, it gives me this error.

I already deleted the '\AppData\Roaming\SDL\SDL Trados Studio\14\Plugins\ ' content.

Is Studio 2017 SR1 incompatible with this framework ? Or did I miss something else ?

Thanks for your help
