PayPalCheckoutSdk Could not install package .net

[CgyDev0101]

I'm trying to NuGet the PayPalCheckoutSdk for my project but, I get this error?

Could not install package 'PayPalCheckoutSdk 1.0.0'. You are trying to install this package into a project that targets '.NETFramework,Version=v4.5', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author

I'm fairly new to .net development so I'm stuck and looking for help.

Thanks in advance

I figured out the issue.  This package depends on NETStandard 2.0.  The NETFramework that is NETStandard 2.0 friendly is 4.6.1 and later.  So I upgraded my projects to 4.6.2 and now it installs just fine.
