Using polymorphism to update Orleans Project to be ready for new Orleans Examples!

Note this is not an Orleans post, not exactly — it’s just something I wanted to enhance on my Orleans Project, prior to moving on to demonstrating even more Orleans features! (Also, I need to learn more Orleans features to demonstrate!)

Prior to continuing with my Microsoft Orleans series, I wanted to make the Console app calling my Orleans Grains a bit simpler to use under the various examples. How can I do that? Polymorphism to the rescue!

In the previous few Orleans posts (links at bottom) I was swapping in/out calls to various Orleans methods in my Console app’s Program.Main.

That looked something like this:

using (var client = await StartClientWithRetries())
{
 //await DoClientWork(client);
 await DoStatefulWork(client);
 Console.ReadKey();
}

In the above, as I added new Orleans functionality, I would simply tack on additional calls and/or comment out previously used functions. I’m not sure how far I will go with these Orleans examples, but since this is going on my third or fourth sample, I wanted a better way to manage these calls. In addition, give the user of the console application the option of choosing which function to play with, without having to require them to change code in between runs.
