1. Install-Package IoTDMClientLib -source nuget_path will fail unless path is added to NuGet sources first
2. It needs to be made clear where the code samples are added or the project cannot build. Alternatively a sample file or project would be useful.

Thanks evan-morris.

I've updated the instructions to explicitly say the nuget source need to be added to VS.

For the 2nd bullet, we are indicating what file the changes should be made in. Do you think this needs to be made more clear?

[evan-morris]

I’d say yes: since you can’t paste the code just anywhere in the file. You could have comment blocks in the template saying “/* paste part 1 here */” etc,

I see, thanks for the suggestion. I will update the sample code.
