Package IDs and assembly ownership

Microsoft and System namespaces are reserved on nuget.org. DotnetEx backport package IDs therefore use the HFDotnetEx. namespace while their output assembly names keep the official assembly identities required by the target framework routing.

For example, HFDotnetEx.System.Linq.Ex supplies the legacy LINQ backport package while its assembly remains System.Linq.dll. HFDotnetEx.Microsoft.CSharp.Ex supplies the legacy runtime binder package while its assembly remains Microsoft.CSharp.dll.

Native-owner routing

HFDotnetEx.Microsoft.CSharp.Ex supplies the backported Microsoft.CSharp runtime binder on .NET Framework 2.0-3.5. On .NET Framework 4.0-4.8 the package intentionally does not expose the backport DLL and the framework-owned Microsoft.CSharp assembly remains authoritative. On modern .NET the runtime-provided binder remains authoritative.

HFDotnetEx.System.Core.Ex is the .NET Framework 2.0/3.0 System.Core backport. .NET Framework 3.5+ keeps the native System.Core owner. The legacy Dynamic/Combined packages similarly stop exposing their backport assemblies once native ownership takes over.
