I'm trying to create a new Azure WebJobs project targeting .NET Framework 4.7 but it's not available in the drop down -- see below:
And if I try to install .NET Framework 4.7, I get the message that it's already installed on my computer -- see below:

Any idea why?
P.S. This may or may not be relevant but my ultimate objective is to create a WebJob that can use class libraries that are created in .NET Core 2.0. If I understand it correctly, .NET Framework 4.7 can use class libraries that support .NET Standard 2.0. I didn't necessarily do anything special when I created my class libraries in .NET Core 2.0. Not sure if I should assume they automatically target .NET Standard 2.0 or I need to specify it somewhere.
Also, the version of Visual Studio I'm using is Visual Studio 2017 - 15.3.3
