Adding file using F1 command palette fails

[einari]

It fails with the message:
"Unable to find project.json or *.csproj" when hitting F1 -> "New C# Class".

Works fine when right-clicking the folder in the explorer and selecting "New C# Class" from there.

Environment:
OS : macOS Sierra
VSCode version: 1.12.0

Same issues here. Works fine when right clicking folder but not from the command pallet
