The best way to add injection

I always wonder where to put my injections...

  1. in the RAZOR page (@Inject ...)
  2. in the partial class ([injec] ...

What is your opinion?

dvoituron commented

In my opinion, I prefer to put all the code in the "Code Behind" file.
And therefore, to put the injection in the .cs.
The .razor is only used for the design part and the layout of this HTML design (via loops and Razor tests)

Do you inject in private or public properties?

  • private Factory Factory { get; set; }
  • public Factory Factory { get; set; }
tossnet commented

in my case, all in private

dvoituron commented

So, a best practice will be

[Inject]
private IMemoryCache MemoryCache { get; set; }
  • 👍1

and you ?

dvoituron commented

In my best practices, all attributes are above of the property/method... so, including [Inject]
The first reason is, because you can have multiple attributes : serialization, authorizations, decoration, injection, ...

OK, Right ! I'll change my code
I need to use #REGION now... :/

It's for this reason, I'm using a Factory pattern to include all service references into a Factory class.
So, in my component / page, when I need to use a service of my project, I inject Factory and I use the property Factory.Profiles.

Factory class

public virtual ProfileService Profiles => _profileService ?? (_profileService = new ProfileService(this));

public virtual AccountingService Accounting => _accountingService ?? (_accountingService = new AccountingService(this));

If the service is provided my Microsoft or external library, I inject the service directly to my component.
The Factory is used only for my services.
