OO Support Tip: .NET operations are invalid in OO 10.20 Studio
OO 10.x requires Microsoft .NET Framework 4.5 or later, full installation.
This is also required for debugging flows with .NET operations.
If you don't have .NET 4.5, any flows or operations with .NET will be marked as invalid in Studio.
If .NET 4.5 or later is installed and still the .NET operations are marked as invalid, please close Studio and re-open it with Elevated Priviledges (Run As Administrator).
