When running with a Debug build pages are loaded into individual assemblies that change every time you save the file (especially when using Browser Link). When running with a Release build pages are loaded into a PrecompiledViews assembly. These assmblies only have partial version information.
When using a TagHelper in an external library calling GetType() will return the external assembly rather than the assmbly running the web site.
