Wrong reference assemblies used when targeting .Net 4.6.2 (and in some cases 4.5.2)

[Daniel-Svensson]

If targeting .Net 4.6.2 then the reference assemblies for .Net 3.5 is used when targeting 4.6.2 since 4.6.2 is missing from the switch statements in the target files.

If targeting .Net 4.5.2 (using v12 tools) then the reference assemblies for .Net 3.5 is used when targeting 4.5.2 since 4.5.2 is missing from the switch statements in the target files under v12 (it is part of v14 target file) .
