I'm developing a simple Console application. Program.cs initialize dependency injection, set file names, accept inputs and print the result.

I got a note that my Program.cs violates the SRP principle ,Program.cs must accept the inputs and print the results, must initialize dependencies. I don't know how to fix that, please advice.
