问题 The structure of projects looks like this: Cars (ASP.NET Core MVC. Here we have a connection string ) Cars.Persistence (ASP.NET Core Class library.

问题 I've encountered this problem, and I couldn't figure it out. I'm using ASP.NET Core 2 and Ajax.

问题 I have a class that requires ApplicationUser (from ASP.NET Identity). The instance should be the current user. public class SomeClass { public SomeClass(ApplicationUser user) { Currently, what I'm doing is I inject the current user from the Controller: var currentUser = await _userManager.GetUserAsync(User); var instance = new SomeClass(currentUser); Now I want to use Dependency Injection provided by Microsoft.
