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!

I saw a message when running the project saying "the extensionsmetadatagenerator package was not imported correctly" Try adding the Microsoft.Azure.WebJobs.Script.ExtensionsMetadataGenerator nuget package to your project. It is suppose to be loaded as a dependency of Microsoft.NET.Sdk.Functions package, But I didn't see it in my project dependencies list. This worked for me.

Or you can just update to

<TargetFramework>netcoreapp3.1</TargetFramework>

If you are not on 3.1

I know this is an older post. I am using JetBrain Rider on a Mac. The only way I've gotten around this is to reinstall .Net 5 even though I am building the Function in .Net 6. Any updates that happen to .net 6 is requiring me to reinstall .net 5.
