Where's the best place to get help with API sample code

I would like to run the sample API connection code.  Is this the right site for these (http://myob-technology.github.io/AccountRight_Sample_vb.net/) - as it seems to refer to Visual studio 10 and accountright 2013?

I am using the latest visual studio: Community 2019

When I tried to run the nuget in the package manager console (i.e. Install-Package MYOB.AccountRight.API.SDK) i got all sorts of errors:

PM> Install-Package MYOB.AccountRight.API.SDK
Install-Package : Some NuGet packages are missing from the solution. The packages need to be restored in order to build the dependency graph. Restore the packages before performing 
any operations.
At line:1 char:1
+ Install-Package MYOB.AccountRight.API.SDK
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (:) [Install-Package], InvalidOperationException
    + FullyQualifiedErrorId : NuGetMissingPackages,NuGet.PackageManagement.PowerShellCmdlets.InstallPackageCommand
 

If you can lead me in the right direction to get a simple sample code running, that would be great - happy to read documentation - i went to the 'getting started' site already, but nothing there i could find about running some sample code.

thanks
