@inject IConfiguration _config

and access all that i need like : _config.GetConnectionString("default")

but how can do the same from any class? when i try to do

IConfiguration _config;

i understood how it work so i can answer my question myself

in fact, you just have to add a constructor in your class with Iconfiguration as argumentand you can use it and call your data stored in your app setteing:

    public class MyClass 
{
    public MyClass (IConfiguration config)
    {
        _config = config;
    }


    private readonly IConfiguration _config;
    


    void MyMethod(){
            .....
           }
}

You can use it after in your method:

string myCon = _config.GetConnectionString("Default");
