Your online tutorial was excellent Andrew. Thanks for posting it. You should do well with your grades on that. I would not have even attempted installing your project without that resource. I'm unable to locate a project to change properties. I've installed the serial socket redirector and suspect it's working fine. I've downloaded your Uno test program. When I run the program it brings up the main screen with the Uno photo, but will not function. I've got the right port number, and localhost is the correct address for my machine. I've edited the port settings so they match on the serial socket redirector. The program connects but fails to do anything else. So I'm pretty sure it's the resource sandboxing that stands in my way.
I downloaded MS Visual Studio just to unsandbox the program. There is no menu selection that is anything like your example. Even though I've downloaded your test program, VS doesn't see it, so I can't change the properties. Maybe I've got to download your source and build the project myself to have this option?? I hope not as dealing with a new MS product is not my idea of fun. 
I've whiled away over 8 hours on VS and filled up 9 gigs of my hard drive with it! LOL
