Having (foolishly, based on experience so far) upgraded to Visual Studio 15.6, I'm getting the message about Xamarin Components:
I've been through the csproj files and removed any that are clearly Components. Followed the instructions on the linked documentation page. Still getting the message though. Is there anywhere that Visual Studio 15.6 logs or outputs what it considers to be the problem components? The message being displayed is an example of really bad UI - tell the user there's a problem, but not identify the problem properly. That's right up there with engine management lights on cars (surely a device primarily intended to raise money for car mechanics/franchises).
I have a solution with multiple projects, many of which make use of third-party plugins etc. Stripping everything down and adding bits back to find the cause is going to make the whole upgrade of Visual Studio leave an even worse taste than it already has, so I'm hoping there's a detailed log somewhere that tells me what VS thinks is the problem.
