Class separation

I've got a console app that does a lot of heavy lifting. Let's say it's got a service class (that performs http calls) as a dependency and the main class is calling it a multitude of times. The unit testing for the main class of the console app is becoming huge. Is it a good approach to just create a class that aggregates all the calls to the service class?

In App Billing purchased fetching on mac os causes restore failed issue sometimes

I am trying to use the InAppBilling plugin library by james montemagno (https://github.com/jamesmontemagno/InAppBillingPlugin) in an avalonia program. I have setup subscription and well configured the settings, info.plist and entitlements for this purpose. But the problem is, the library, when fetching from app store, it sometimes work and sometimes says failed due to restore issue, which I think means that it was not able to connect to app store and fetch purchases.. I saw a solution saying that we just have to keep trying in a loop, but still the error is not clearing. It particularly happens when I am trying to fetch purchased subscriptions list to check if the user has purchased our product or not. Has anyone ever faced this and found solution for it? Looking forward for any help. Thank you!...

How to to dynamically provide T type of a generic method

I am having an interface declaration which has many-many implementations. The usecase/logic is similar, but the return type differs. (tldr: the services parse and validate data extracted from different systems. They each return the parsed structure relevant to the given system and the detected errors). I want to achieve something like this, however I cannot pass the Type retrieved from the specific implementation in the method call. The services are provided through factory pattern. ...
