I have tried the ASP.NET/EF Core 2.0.3 patch and the scaffolding issue is still there.

@ksahota - Did you re-scaffold database or upgraded package in already scaffolded code?

[ksahota]

@smitpatel , Upgraded package in already scafolded code .

[smitpatel]

This fix does not solve that issue. You manually have to edit generated file in existing files. Or you can delete scaffolded code and re-generate them. This fix stops producing incorrect code.

Seems to be working. Thanks @smitpatel
