Well, as close as you can get to that is to go to the portal, your Function App, then click Download app content button and ask for Visual Studio solution:

This will give you a zip file with Functions, including csproj file.

The problem is that portal functions are C# scripts (csx files), and Visual Studio isn't great to work with them. When you create a new Function App in Visual Studio 2017, it will make a precompiled function project - a normal class library with cs files.

Unfortunately, there is no automated way to convert script functions to precompiled ones.
