Is it better to create a singleton to access unity container or pass it through the application?

The correct approach to DI is to use Constructor Injection or another DI pattern (but Constructor Injection is the most common) to inject the dependencies into the consumer irrespective of DI Container .

You should not really need to use your container directly in very many places of your application. You should take all your dependencies in the constructor and not reach them from your methods. You example could be something like this.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
