✅ Do I always need to avoid coupling?

For example, I have a class Application where the main part of my project's logic is written, and I also have a GenerateVocabulary object which will itself use an Interface to actually generate content. Will it be good practice to simply create this object inside my Application class? And in general, is it acceptable in a professional context to create one object inside another if I'm 100% sure that I won't change it?

Best way to deserialize duplicate JSON API responses (Using Newtonsoft.JSON)

I'm using a HTTP client to contact an API, and then deserializing the JSON response into an instance of its respective object type. My issue is this - the API has two versions: - Version 1: The old API, but still active, however, it's not maintained and may be missing bits of data that are present in requests made to v2 of the API. - Version 2: The new API. Almost identical responses to v1, but all of the fields are obfuscated....

When to use Dependency injection?

I am learning WPF and since I am used to work with DI almost always in my previous projects (mostly APIs) I am not sure if I need it. Is using DI in wpf really best practice? My app is currently not really complicated, I only have some kind of Get data from API and save to db. Is DI recommended in this case? or does wpf have any special "best practices" what should you work with?...

fastest way to check if list doesn't contain null ?

I have a list of reference type (for example, list of string) as constructor parameter. Now i require that all of the list element must not be null. Everytime the object instance is created, the constructor will loop through the list to verify that none of the element is null. However, this have performance impact to immutable class where any modification require creating new instance of the class (because immutable class can't be modified). Is there faster way to check that list element cannot...
