Package reference in ASP Core 3.0

I encounters an error when running the ASP Core app. Actually, I have no idea which Microsoft.EntityFrameworkCore should I refer in my project ? I suppose my app is running 3.0.0-preview8-28405-07. Am I correct ?

Hi Simon,

Without error description it is impossible to guess which error you are encountering, my advice is always describe the error properly so that it becomes easier for others to help. I see you are using a Preview version of .Net core, and I would advice against using it as Preview versions can spring random errors - especially when you are migrating from an older project.

Also, I noticed that you are using Visual Studio Code. Any specific reason for not using Visual Studio Community or other editions?

I'm taking a stab in the dark here, but would you not need Entity Framework Core 3.0? Refer to Announcing Entity Framework Core 3.0 Preview 7 and Entity Framework 6.3 Preview 7.
Thx. Restore package back to Microsoft.EntityFrameworkCore 3.0.0-preview.18752.1 seem fine the problem..
