Failed to resolve for reference Microsoft.Azure.WebJobs.Extensions - Metadata generation failed

Had to pick up a bit of work from another developer so just trying to wrap my head round it all!

But I'm having issues building an Azure Functions project and continuously getting a error coming form Microsoft.NET.Sdk.Functions.Build.targets , specifically unable to resolve a reference to Microsoft.Azure.WebJobs.Extensions.

So far I have attempted re-installing the Nuget Package, Re-Starting Visual Studio, my machine yada-yada.

I would welcome any suggestions and appreciate your time!
