Is it possible to create a Microsoft Management Console Snap-In with .NET? I know about the MMC Snap-in Designer for Visual Basic – but don’t know if there is anything newer or pre-canned for the .NET world.
From my quests on the net, I found that Microsoft declares it as possible, but not recommended.
I have personally created an MMC clone, purely in .NET, to avoid problems.
