Update Visual Studio projects that don't contain Util.cpp

[amartin7211]

I could get things working with the project generator but opening the files directly resulted in linking errors do to the absence of Util.cpp. In order to use the project generator, I used the import button and used the directory to the example_client_hello_world folder and then pressed the update button. May want to add this to the readme

Apologies for that, can update soon!

Hm, really quick: are you working from the master branch? As best as I can tell the projects should have Util.cpp included now. I think this was a past issue, but I might be wrong!
