ORMLite with ServiceStack mvc template

[mythz]

I’ve answered this in your other question

ServiceStack MVC - is there a problem with .Net Core2.1

No from v5 a .NET Core App should not have any .Core packages, they should only be used for running ASP.NET Core Apps on the .NET Framework, not for .NET Core Apps.

Don’t reference .Core packages in a .NET Core App, reference the normal ServiceStack packages only, e.g. Servicestack.OrmLite.SqlServer.

Your ServiceModel project should not reference any other dependencies except ServiceStack.Interfaces. It should only contain your DTOs and no other concrete dependencies, for background info see this article on purpose of DTOs.

Any Server implemention logic should remain in ServiceInterface, also only your host project needs the concrete RDBMS ServiceStack.OrmLite.SqlServer dependency, your ServiceInterface project only needs ServiceStack.OrmLite. Have a look at code bases of existing .NET Core Apps like TechStacks for examples.
