Error message when running EF cmd to update database [attachment=0:1v8222or]message for ef database update.jpg[/attachment:1v8222or]

Is there an approach define navigation menu in module A, then initialize the navigation provider in main App? I also tired but navigation menu didn't show, how to archive it?

Yes, via "cd" command changed to root direction of the *.EntityFramework,then run "dotnet ef database update", I will share you a screenshot tomorrow

When using project.EntityFramework do the database migration, it not succeed. Rum from cmd line, using 'dotnet ef database update', got below message: "Could not find content root folder!"

What happened? No exception was thrown.
