On ASP.NET Core view components support dependency injection. We can use some DI/IoC container but we can also go with framework level dependency injection. This blog post explains how dependency injection works with view components and as an example I show you some code I’m using to build top menu for my demo site.

Dependency injection in ASP.NET 5

ASP.NET 5 has dependcy injection available at framework level and ASP.NET 5 makes heavy use of it.

We can face different problems when test users start testing system in their environment and we want to be ready to react fast to all problems. To get information about system’s work we need advanced logging.
