## Devnote:
### .NET
According to Ozzah:
> I suggest `Solver.EnableOutput()` needs an overhaul. Specifically, I may not want to write directly to the console and I may not want to write it to a file. In C#, it's common to use `ILogger` to record information, either to screen, file, database, Kafka, etc.
In C#, when we create and start a `Process`, we can override the `Process.StandardInput`, `Process.StandardOutput`, and `Process.StandardError` with our own `StreamReader` and `StreamWriter` implementations.
I think it would be useful to be able to supply a `StreamWriter` to `Solver.EnableOutput()`, and that way it's up to us to decide what to do with that output.
