Problem configuring code analysis for .NET standard 2.0

Hello,

I'm starting to move an old full framework code to .NET standard 2.0
I created a new project, added one class to this project, now i'm trying to add code analysis to the solution and it fails.

I followed up the 3 steps of the "how to" [https://github.com/JosefPihrt/Roslynator/blob/master/docs/HowToConfigureAnalyzers.md#new-csproj-format-net-core-net-standard](url)

Then, when I try to analyze the solution, I got no error (while I should have) and when I right-click the solution \ properties \ code analysis settings, I get the following message "There are currently no analyzable projects loaded".

I this a bug, or did I missed something ?
