When I run
dotnet ef dbcontext scaffold "User ID=ver_user;Password='';Host=localhost;Port=5432;Database=ver_development;Poolin
g=true;" Npgsql.EntityFrameworkCore.PostgreSQL

I get this message error

Hey,

This is because you have a mix of 1.0 and 1.1 packages. You would need to upgrade the AspNetCore and Extensions packages to 1.1 as well.

I had to upgrade Microsoft.Extensions.Logging to 1.1.0-preview1-final and Removed project.lock.json to make it work, thanks!
