runtime: CoreFx implementation assemblies contain duplicate definitions of public types

The public types listed below have multiple definitions in CoreFX assemblies. This causes issues when the assemblies are used in dynamic/runtime compilation scenarios such as C# scripting (see e.g. https://github.com/dotnet/cli/issues/320), dynamic languages, dynamic runtime binders, etc. and in VS Expression Evaluators. All these tools work with implementation assemblies since the reference assemblies are not available.

These duplicate definitions should be made internal.

Duplicate types in recent .NET Core build:

I see, well, good enough too. Hopefully that reflection hack will still work, but anyway we can stop using the hack altogether and just reference a newer version of the standard once that happens. A ping in this thread with a heads up would be valuable if possible when something changes regarding this.

We ran into this issue with our runtime code generation in dotnet/orleans while porting to .NET Core/Standard. Currently I’m trying the reflection-based hack implemented by @vors for PowerShell.
