WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

It’s a test Domain Controller and I wanted to test something out. First time install, straight install of Preview Extension, and only that extension.

I’ve have a fix for this, linked above and have tested it on Windows Server 2016 with .NET 4.6.2 and .NET 4.7.0. So this should be fixed in the next release.

Experienced the very same issue today on a fresh install, Windows Server 2016. I’ll now try the workaround of installing .NET Framework 4.7.2 or higher.
