all option are enable

it is giving us the hint that 1 dll is available, but still let it unclear which version and the used reference / inclusion.

Still I would suggest that the .net platform / framework / core installation is checked and its availability is validated


I am facing same issue. How do we resolve this. I checked .net version and all paths

.net framework 4.8 is already installed

I thought it was. And since it doesn’t read “jsonObject” (which I would have expected) and the error was that it can’t be processed, I thought it was a miss-spelled variable name.

Could you please share a sample project in which you get the error? You can do it in a private message if you have any privacy concerns.
