Whilst developing a custom DR, everything was fine. Target Framework .NET 4.5.2 as i don't have to consider pre .NET 4.0 clients. So i put my DLL & PDB in the %home64/af/pulugins/4.0 directory and ran regplugin. Everyting works nicely, no issues.
But then i wondered, should not i have used Regplugin64? What's the difference? Regplugin64 does not appear in the sparse documentation (Request Rejected).
