I am making a program in Asp net web apllication, but when I try to communicate the controller with the service the constructor this null saind, the dependencies are already configured in the project.
public HomeController(){}
public readonly OficinaService _oficinaService;
public HomeController(OficinaService oficinaService)
{
this._oficinaService = oficinaService;
}
follows the project on github https://github.com/REIFERREIRA/ProjHi

Remove the empty constructor from your controller:
public HomeController(){}
When Dependency Injection is applied correctly, it is important that each type has only one constructor - multiple constructors are redundant, make your DI configuration fragile and lead to maintenance capacity problems.
Reference:
It does not work if I remove the public Homecontroller(){}, from the following error: No constructor without parameters has been set for this object. I’m a bit of a dead end I’ve tried everything.
@GABRIELVFA did you register DI? Which framework are you using? I couldn’t find it in your project.

Just as an observation, I saw that your service has a constructor receiving the controller as parameter, and the controller receives the service as parameter in your constructor. I believe this redundancy is not correct. Also I did not see (I may not have noticed) any dependency injection configuration in the project...
