| .NET 4.7.1 has support for .NET Standard 2.0 built-in, so most of the facades aren't necessary. However, the assembly versions of a few set of assemblies | |
| do not yet match the ones shipped in the support package for .NET Standard 2.0 on .NET 4.7 and below. This means that .NET 4.7 or lower libraries might have | |
| references to higher versions of these assemblies than are available in-box in .NET 4.7, leading to assembly loading errors. So if there is a dependency on | |

| workaround https://github.com/dotnet/core-setup/issues/2981 by ensuring that the facades are written | |
| to the deps.json with a type of "referenceassembly" instead of "reference". | |
| The exception is netfx.force.conflicts.dll, which shouldn't be copied local. So it isn't included in | |

| When we add the Reference items, we use the simple name as the ItemSpec, and refer to the full path | |
| to the DLL via the HintPath metadata. This is so that if we're replacing a simple Reference, | |
| the OriginalItemSpec of the resolved reference will match to the Reference that was replaced, | |
| and VS won't show a warning icon on the reference. See https://github.com/dotnet/sdk/issues/1499 | |

| <!-- There was issue in .NET 4.7.1 where System.IO.Compression.ZipFile was not correctly in the unification table. | |
| A workaround to issues that caused was to add a binding redirect for the assembly from version 4.0.3.0 down to | |
| 4.0.0.0. However, with the fix to dotnet/sdk#2221, ResolveAssemblyReference now sees a conflicting version for | |
| the assembly, and suggests a redirect to 4.0.3.0. With automatic binding redirection, this overrides the redirect | |
| to 4.0.0.0, which causes a runtime failure. | |
| So here we disable any suggested binding redirect for System.IO.Compression.ZipFile. Assemblies in the unification | |
| table generally should not need binding redirects, so it should be OK to do this for 4.7.2 and forward, and on 4.7.1 | |
| the assembly isn't in the unification table so this allows the original workaround redirect to be preserved. --> | |
