MSB3277 When referencing a framework assembly with newer build or servicing version

[ericstj]

Issue Description

See dotnet/maintenance-packages#243

.NET Framework assembly unification will ignore the last two digits for any assembly in the unification table. So even though the version from the package for previous framework is higher in build or servicing, the runtime will ignore that and still load the version from the GAC.

Ideally RAR would have this same behavior for .NETFramework assemblies in the targeting pack.

Steps to Reproduce

bclMem.zip

Expected Behavior

Analysis

I found that specifying SpecificVersion="True" will workaround this (perhaps unintentionally, since that seems to be the opposite of what I would expect) but it seems better if RAR would behave in the same way as the .NET Framework runtime.
