Dependency Injection Scopes in Blazor

The dependency injection system is a big part of how modern ASP.NET Core works internally: It provides a flexible solution for developers to structure their projects, decouple their dependencies, and control the lifetimes of the components within an application. In Blazor – a new part of ASP.NET Core – however, the DI system feels a bit odd, and things seem to work a bit differently than expected. This article will explain why this is not only a feeling but indeed the case in the first place and how to handle the differences in order to not run into problems later on.

One of the biggest advantages of the new API, which makes the Source Generator an incremental one, is the built-in memoization, i.e. caching. To take full advantage from it, we have to make some preparations so Roslyn knows what to cache and how to compare the results of each phase.

Entity Framework Core: Default Comparer For Byte Arrays May Waste Lots Of Memory And CPU

The default implementation of Entity Framework Core prefers to play it safe (for good reasons) when working with byte arrays. This ‘safety’ is – in some use cases – unnecessary and costs us a lot of memory and CPU. In this article, we will see that doing less is sufficient for the given property thanks to one of the most overlooked features of Entity Framework.
