Hi, K-Korm
If your have unregistered the configuration, the MMC snapin cannot load it.
Same thing, for PowerShell, or the web Site.
So try to run Register-MFASystem.
And After run Import-MFASystemConfiguration with your saved config file

Hi redhook62, thanks for the suggestion.
Tried to run "Register-MFASystem" and "Import-MFASystemConfiguration". Both completed successfully, however error still persists.
The thing that is suspicious for me is that MMC tries to load "Neos.IdentityServer.Console, Version=2.0.0.0" (version = 2.0, and not 2.2), and that assembly is not available.

I run into the same issue in one of our LAB domains. (First domain where I tested the 2.2 beta, it worked fine. Then I was going to test in an other LAB domain, I did the same thing, but there I run into this problem.)
I then tried Unregister, Uninstall, Restart and then Install and Register again (tried both restoring and not restoring old config). But I keep getting this "Unhandled Exception..." too when I try to open the MMC.
Could not load file or assembly 'Neos.IdentityServer.Console, Version=2.0.0.0, Culture=neutral, PublicKeyToken=175aa5ee756d2aa2' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Hi,
On my adfs server 2016 the MMC version is 3.0
These servers exposed on the internet must be updated regulary with Windows Update.
It seems, that the MMC MFA Snap is not well registered (self registration with assembly type at install for x64 and x86 registry access). I can reproduce your problems with ADFS on Windows 2012 R2 !
Lauch Regedit as administrator
Select HKEY_CLASSES_ROOT
Search for : FX:{9627f1f3-a6d2-4cf8-90a2-10f85a7a4ee7}
In the right pane look at the Type attribute and modify the version with 2.2.0.0 if needed.
I think, you can Import your saved config file with Import-MFASystemConfiguration.
Surely, a security problem with OS, the new assembly not seems to register itself correctly.
I will check that this Week-end
