Toy Robot implementation using .NET Core (Specification from Question 2 posed by OP here: https://groups.google.com/forum/#!topic/happy-programming/O0-lg6yn1F0). Lots of other implementations for comparison (https://github.com/search?l=C%23&o=desc&q=toy+robot&s=updated&type=Repositories).

run:

$ dotnet restore
$ dotnet test
$ echo -e "PLACE 0,1,NORTH\nMOVE\nREPORT\n" | dotnet run

output:

0,2,NORTH

For self-contained deployment remove the "type": "platform" part from the frameworks section of the project.json file.

Then publish with:

$ dotnet publish -c release -r ubuntu.15.10-x64

And to run (from within the bin/release/netcoreapp1.1/publish/ directory):

$ sudo chmod +x ./PassInTableDimensions.dll
$ echo -e "PLACE 3,4,NORTH\nMOVE\nREPORT\n" | ./PassInTableDimensions.dll 5 7

output:

3,5,NORTH

For an IDE Rider is currently easier to use over Visual Studio Code, (though both took more work than I was prepared to do to actually get building/running working through the IDE).

Using Moq (https://github.com/Moq/moq4/wiki/Quickstart) and XUnit (http://blog.benhall.me.uk/2008/01/introduction-to-xunit/).
