Konflikt między dwoma referencyjnymi złożeniami

Question

Gram z aplikacją .Net Core, która działa poprawnie. Jednak dzisiaj stwierdziłem, że output zawiera ostrzeżenie. Po ustawieniu poziomu dziennika detailed znalazłem następujące:

Linia There was a conflict between "Microsoft.Extensions.DependencyModel.... Nie wiem, jak to ostro obejść, ponieważ używam tylko pakietu .Net standard 1.1 i System.Reflection.Emit od NuGet i nie odwołuję się do niczego innego.

Oczywiście, można po prostu zignorować to ostrzeżenie, ale patrząc na niektóre rozwiązania

Answer 1

zgodnie ze szczegółowymi dzienniku okazało się, że zależność „Microsoft.Extensions.DependencyModel, Version = 1.0.1.0, który jest wymagany przez Ale ta zależność z Version = 1.0.0.0 jest już zainstalowana

Kiedy więc skompilujemy projekt, ta zależność z Version = 1.0.0.0 zostanie wybrana, co spowoduje ten konflikt. NuGet, aby dodać zależność "Microsoft.Extensions.DependencyModel" z podaniem wersji = 1.0.1.0, aby rozwiązać ten problem z ostrzeżeniem:
