嵌套Visual Studio项目以进行选择性共享

Question

This may be a duplicate of Nested projects in multiproject visual studio templates ...

I have a Visual Studio solution a solution folder in it to hold all of my projects. Within that folder are a Windows Phone project, a Windows 8.1 project, and a shared project. This is what VS studio will create when making a Windows 8 Universal App.

I want to expand on this idea and put the windows non-phone code into two child projects, a W8.1 and a W10 project. Then have a shared project to hold all of the code except for the stuff not in common. The whole thing would looke like this:

solution
-windows
--windows.phone
--windows.notphone
---windows.notphone.10
---windows.notphone.8.1
---windows.notphone.shared
--windows.shared

I can't figure out how to do this since shared project and that windows folder under the solution are solution concepts, not project concepts.

I don't want to target just Windows 10 but I can't figure out another way to target both Windows 8.1 and 10 within the same project.

Question 1 is; how do I create this project structure in my solution.

Question 2 is; how can I instead just have a single windows non-phone project and have it create apps targeted for both 8.1 and 10. I don't mind running the 8.1 app on Windows 10 except that Windows sticks in that extra hamburger button that has nothing in it in my app.

Answer 1

I always find a solution to my problem just after posting the question. In this case, I realized that the shared project is only shared with those other projects that include it as a reference. I can create all of my projects at the same level of the tree, which seems the only way to do this, and then only use the windows-specific shared code in the windows-specific projects. The phone code would not use that windows-specific shared project.

I'd rather have a visible hierarchy though.
