Class LazySvc<TService>

Namespace

ToSic.Lib.DI

Assembly

ToSic.Lib.Core.dll

Helps us create lazy Service objects. It has some special features:

• It will automatically lazy-attach a logger when used correctly
• It can also be configured with a lazy init function to keep code clean.

This reduces the amount of plumbing in many code files.

It will detect if the provided object/service supports these features. So if it's used for anything that doesn't support logging it will just behave like Lazy.
