@Varorbc apologies for delay.
@captainsafia I believe you own area-mvc which includes most templates? could you have a look?

Thanks for this contribution!

It looks great overall! The move to primary constructors here has revealed places where we were initializing but not using ILoggers. I think it might be worthwhile to continue to inject ILogger's into the classes via the primary constructor but add code to use them in the class so that the functionality is properly demonstrated.

Nit: Although the ILogger<GreeterService> was unused before perhaps we can add a log to the SayHello method to more fully demonstrate primary constructors here?

When I moved things to the main constructor, I noticed a bunch of log initializations that weren't being used, which caused our CI to fail. Since I wasn't sure what kind of logs should be output, I had no choice but to remove them for now. If you could provide the correct log outputs for each of the removed logs, that would be perfect.

Suggested change

	var sampleTodos = new Todo[]
	Todo[] sampleTodos = [

Small nit unrelated to your contribution but while we're here perhaps we should update this to use collection expressions?
