Runtime BindingFailure for .NET Framework 4.6.1 project referencing .NET Standard 1.4

[UnoSD]

Version Used:

• Project A: .NET 4.6.1
• Project B: .NET Standard 1.4 csproj
• VS2017

Steps to Reproduce:

1. Add some dependencies to .NET Standard project (E.G. System.IO.Filesystem.Primitives, System.Security.Crypyography.Primitives and others).
2. Reference .NET Standard project from .NET Framework project.
3. Build and run.

The result is a Managed Debugging Assistant 'BindingFailure' as it cannot resolve the .NET Framework implementation of the .NET Standard dependency. Indeed none of the dependencies' .dll is copied to the output folder.

Expected Behavior: The compiler should copy the correct dependency's .dll from the package\GAC to the output folder. Or at least (and probably better), it should automatically add the dependent NuGet packages to the referring project.

Actual Behavior: Runtime exceptions.

The only workaround is to copy or reference the missing libraries manually.

Thank you.

This is tracked by NuGet/Home#4488. Currently, the referencing project has to use PackageReference for transitive dependencies to flow. See discussion for workaround involving a dummy package reference.
