Support multiple target frameworks

[FarmGeek4Life]

I don't know if you are interested in doing so, but you can modify the updated csproj files to build against multiple target frameworks and create a single NuGet package supporting all of them.

If you are interested in doing so, the changes needed in the csproj files to build against .NET 4.5.1, 4.6.2, and Net Standard 2.0 and create a single NuGet package are:

<TargetFramework>netcoreapp2.0</TargetFramework>

to

<TargetFrameworks>net451;net462;netstandard2.0</TargetFrameworks>
<GeneratePackageOnBuild>True</GeneratePackageOnBuild>

The full list of supported "Target Framework Moniker" is here

One advantage of this change (especially after doing the same to R.NET) is that developers wouldn't need to update the project to .NET 4.7 or newer to avoid adding all of the Net Standard DLLs to their compilation output (and to all installers, etc.).

Thank you for this suggestion; I'll see if I can set this up soon. My understanding of targeting monikers is rather ad hoc and patchy as I use .NET less these days. I appreciate the help.
