This is a simple project intended to show a simple implementation of Railway-Oriented programming using C#

It's based on the amazing work done by Scott Wlaschin at F# For Fun and Profit I can't recommend this site highly enough!

You need to have .NET Core installed. This was done using the .NET Core 2.0 Preview 2 with Visual Studio Code to edit, but there's no reason why it shouldn't work on other versions. Given it's just plain C# with no tricks, it should work fine in visual studio as well. Although it'd be pretty easy to remove I've used a few C# 6 features (nameof) so you'll need VS 2015 or later to get it to build.

There are four versions of the code:

1. The optimistic "Happy Path"
2. The unfortunate "Sad Path"
3. The safer but clunky "Safe Path"
4. The railway-oriented "Awesome Path"

If you look at Program.cs you can just execute using different IOC contexts to run the different versions. eg. Handle<V4.V4Registry>(evt); will run the V4 ROP version.

To build:

• Change to the Demo directory
• Run command dotnet build

To execute:

• Change to the Demo directory
• Run command dotnet run

To run the tests:

• Change to the Tests directory
• Run command dotnet test

Note that these are all set up as build tasks, so in VS Code you can just use Run Task... or do F5 to run the code
