@PaulWhite The NuGet package was only built to be compatible with a specific .NET and OS version (net6.0-windows10.0.17763). So Sean needed his C# project to also target that version.
It's weird, because normally Visual Studio and / or NuGet will give you feedback about incompatibilities like that.
So I think the metadata on the NuGet package is not filled out right.
Instead, the project built, NuGet restore worked, but it didn't copy any DLLs into the bin folder, because there were none to match the plain net6.0 target framework.
Current standings - Sunak 86, BoJo 44, Mordaunt 21. Expect a load of declarations for Sunak tomorrow and he will, reluctantly of course, "allow" his name to go forward...
