Method not found while Scaffolding in a brand new project

[aleksamagicka]

I created a brand new project ASP Net Core project with auth and added two model classes, StudentGroup and Student, which can be found in the repro project. The StudentGroup contains a name and a List of Students, which should work (One to Many).

I ran a scaffold to generate the controller and views, and it failed with the following error message:

There was an error running the selected code generator: 'Method not found: 'Boolean Microsoft.EntityFrameworkCore.Metadata.IProperty.getIsShadowProperty()'.'

Further technical details

EF Core version: 3.0.0-preview4.19216.3
Database Provider: Microsoft.EntityFrameworkCore.SqlServer (the default one)
Operating system: Windows 7 x86
IDE: Visual Studio 2019. 16.0.3
