I have a better understanding of the new runtime, the tooling, and the dependencies required to build applications
In .NET 6 (preview 4), two long-awaited types have been introduced as part of the core library. DateOnly and TimeOnly allow developers to represent either the date or time portion of a DateTime. These two new types are structs (value types) and may be used when your code deals with date or time concepts independently. Both types can be found in the System namespace. Using these new types may align well with how databases allow similar data to be represented. Specifically, these types align well with the SQL Server date and time data types.

در متن آمده که EF Core به صورت پیش فرض ، Db Context را به صورت Scoped ثبت می‌کند. و نحوه تزریق از طریق سازنده کلاس‌ها است. از طرفی اگر درست متوجه شده باشم در مستندات ماکروسافت هشدار داده شده که این مدل طول حیات را نباید از طریق سازنده تزریق کرد.
When using a scoped service in a middleware, inject the service into the Invoke or InvokeAsync method. Don't inject via constructor injection because it forces the service to behave like a singleton. For more information, see Write custom ASP.NET Core middleware.
همچنین شما گفتید که "سرویس‌های Scoped در محدوده‌ی درخواست، مانند Singleton عمل می‌کنند و شیء ساخته شده و وضعیت آن در بین تمامی سرویس‌هایی که به آن نیاز دارند، مشترک است. بنابراین باید به این نکته در هنگام تعریف سرویس به صورت Scoped ، توجه داشته باشید."
در پروژه‌ای که روی آن کار میکنم (ASP.NET Core Razor Pages) یک کلاس validation هست که میخوام به عنوان یک سرویس به کلاس هر صفحه تزریق بشه. اگر امکانش هست توضیح بدید که بر اساس مواردی که در بالا آوردم و هدفی که دارم آیا بین حالات singleton و scoped فرقی وجود دارد؟
ممنون.
Today we are glad to announce an alpha release of SignalR for ASP.NET Core 2.0. This is the first official release of a new SignalR that is compatible with ASP.NET Core. It consists of a server component, a .NET client targeting .NET Standard 2.0 and a JavaScript/TypeScript client.
Redis (REmote DIctionay Server) is a very popular open-source, networked, in-memory, key-value data store, sometimes referred to as a data structure server which also comes with optional durability. Redis is well known for high performance, flexibility, provides a rich set of data structures, and a simple straightforward API.

Application Pools in IIS can be somewhat of a mystery. Since they’re created for you automatically many times Administrators don’t give them a second thought. But understanding application pools is crucial to having a good running IIS server.
