I'm tryng to refactor a monstrous WCF service into something more manageable.
At the time of writing, the service takes about 9 dependencies via constructor, which makes unit testing it very difficult.
The service is handling local state via state machine, does validation on the parameters, throws fault exceptions, performs the actual operation and fires publication events via a pub/sub channel. This code is very similar accross all other service calls.

I realize that I can do several of those things (argument validation, pub/sub notifications) differently, perhaps via WCF behaviors, but my gut tells me that the general approach is wrong -- this feels too "procedural".

I wonder if acronyms like DDD or CQRS or other techniques can help out here?

Thanks!

I'm working on a small project, inspired by the awesome System.IO.Abstractions, aiming to provide a wrapper over System.Diagnostics.Process, to assist testability of anything process-related.

Where System.IO.Abstractions provides a wrapper over the Path, File, Directory types, as well as a wrapper objects over FileInfo and DirectoryInfo, all conveniently accessible from an IFileSystem, mirroring the way those types exist today in the .NET framework, the System.Diagnostics.Process type presents its own challenges when trying to create a convenient wrapper.

Your feedback on the API is, therefore, very much appreciated.

The Process class has several static methods for launching a new process, as well as other stuff:

void EnterDebugMode();

Process GetCurrentProcess();
