I’m just wondering how other developers tackle this issue of getting 2 or 3 answers from a method.
1) return a object[]
2) return a custom class
3) use an out or ref keyword on multiple variables
4) write or borrow (F#) a simple Tuple<> generic class

I’m working on some code now that does data refreshes. From the method that does the refresh I would like to pass back (1) Refresh Start Time and (2) Refresh End Time.
At a later date I may want to pass back a third value.
Thoughts? Any good practices from open source .NET projects on this topic?
Your question points to the possibility that you’ll be returning more data in the future, so I would recommend implementing your own class to contain the data.
What this means is that your method signature will remain the same even if the inner representation of the object you’re passing around changes to accommodate more data. It’s also good practice for readability and encapsulation reasons.
