4. Supporting a scenario of performing a BuildUp() on an existing instance of a class that doesn’t have a public constructor:

To make the update experience as simple as possible for users and to avoid the need for assembly binding redirects, we chose to only increment the assembly file version, not the .NET assembly version.
