Different versions dll in nuget

[KopIlya]

Hello. When update nuget on 2.2.1.0 version. In folder packages in folders net40 and net45 have dll version 2.2.1.0. But in folder netstandard1.5 have dll version 2.0.275.0. This is a bug or feature?
When I debug .netFramework who referenced netstandard project with commandlineparser I have error:

=== Pre-bind state information ===

Hey, I got a similar binding error and also see these 2 versions in one nuget packages. Is this a bug?

Having this same issue using CommandLineParser 2.3.0. If you reference it from .Net framework you reference assembly with version 2.3.0, if you reference from .Net standard you reference assembly 2.0.275.0.

This is causing me issues in Xamarin Android processes.

@ericnewton76 I believe this one might have been fixed by your recent .net standard 2.0 adoption.
