Service object initialization approach/ Static

Question

Hi,

 

I am using IBusinessService class. I use one helper method to create instance of this class.

 

creating instancce of this class is Expensive and takes time. I want to avoid create instance when IBusinessService already initaizalize.

 

class A

{

    private readonly IBusinessService _service = API.BusinessService(); 

    

   method1();

   method2(); 

    

} 

In above _service always created.

 

Using static suffices but observed break sometimes. application is api based so static is not recommanded I guess.
