[wix-users] Installation of assembly into GAC isn

> Unfortunately Microsoft didn´t change the AssemblyVersion of these
assemblies between the two versions (it´s always 6.0.0.0). We don´t

This is done to avoid changing the publicly exposed interface. This
allows updating the assemblies used by all applications in one fell
swoop. There are lots of arguments as to whether this is a good idea.
A comment from Heath Stewart on a blog post from back in 2010 will fix
this:=====================@Kiran, if that works, great. But it's not a
documented sequence of RemoveExistingProducts so I can't really
recommend it, nor can I recommend against it.To populate the
fileVersion "attribute" in the MsiAssemblyName table, it depends on
your build environment. If using WiX, pass the -fv switch. In a
.wixproj, add the following to a
PropertyGroup:True=====================https://blogs.msdn.microsoft.com/heaths/2010/04/09/major-upgrades-with-shared-components/
Searching for SetMsiAssemblyNameFileVersion will bring up more
information on what this does.
I have been using this in an installer for a number of years and it
works fine.
