Alors qu’approchent les fêtes de Noël et les traditionnelles préparations de pâtisseries à la maison, l’UFC-Que Choisir publie un test exclusif sur les moules en silicone…
Tous les moules en silicones ne sont pas pour autant à proscrire. Notre test démontre en effet que certains fabricants comme Tefal ou Ikea (6) vendent des moules quasiment inertes vis-à-vis des aliments.

ZonedDateTime
It should also be pointed out that Noda Time has a representation called ZonedDateTime for this, while the .Net base class library does not have anything similar.
You would need to store both a DateTimeOffset and a TimeZoneInfo.Id value.

Learn about the new features in ASP.NET Core 7.0.
ASP.NET Core provides two primary methods allowing developers to cache information; IMemoryCache and IDistributedCache. Selecting the proper caching implementation requires an understanding of your application, your future goals, and the features of both options. This post explores cache strategies.
In this post I discuss C#'s nullable reference types in the context of Razor Pages, why they don't play nicely together and how to improve the experience.
