Entity Framework Core ObjectContext.Refresh equivalent?

[viveknuna]

With Entity Framework 6, it was possible to refresh all the context with the method : _myObjectContext.RefreshAsync(RefreshMode.StoreWins, GetAll())

I would like to do the same thing with Entity Framework Core, but I can't find the best way to do that.

So, what's the best way to refresh all the context with EF Core?

@viveknuna There isn't currently an equivalent in EF Core. context.Entry(foo).Reload() is currently the closest thing, but it only works on a single entity.

In general, we recommend using short-lived contexts that cover a single unit-of-work. This usually makes reloading from the store unnecessary.

Could you please explain “short-lived contexts that cover a single unit-of-work”. Please provide sample code if possible.

@viveknuna That is, create a context instance, query for the relevant entities, make changes, save changes, dispose of the context. See https://www.martinfowler.com/eaaCatalog/unitOfWork.html for info on the unit-of-work-pattern.
