.NET Standard 1.x project build break from ThisAssembly's use of ExcludeFromCodeCoverage

[maxkatz6]

New attribute was added to ThisAssembly auto-generatred file with condition '#if NETSTANDARD || NETFRAMEWORK || NETCOREAPP'. But ExcludeFromCodeCoverage itself available only from NETSTANDARD2_0.

Minimal repro: use Nerdbank.GitVersioning in netstandard1.4 project.
Workaround: declare ExcludeFromCodeCoverage in user code.

Full error:
CS0234 The type or namespace name 'ExcludeFromCodeCoverage' does not exist in the namespace 'System.Diagnostics.CodeAnalysis' (are you missing an assembly reference?) Assembly (netstandard1.1)

I see two possible solutions:

1. In condition should be long list of target frameworks, where ExcludeFromCodeCoverage is not available. Like "#if NETSTANDARD1_0 || NETSTANDARD1_1 || NETSTANDARD1_2 ... || NETCOREAPP1_0". And I am not sure about some UWP and Xamarin frameworks.
2. Use special constant, which can be defined by used. Like 'NULLABLE_ATTRIBUTES_INCLUDE_IN_CODE_COVERAGE' in https://github.com/manuelroemer/Nullable
