I make a new C++ Dynamic DLL project (non UWP!) in VS 2017. Can’t get it to compile with /ZW (C++/CX). Why not? Please, don't answer "make a UWP project", that's not the question here. I can make UWP projects that compile just fine. I have seen a lot of sample code out there for C++/CX projects that are not UWP targets, they just don't compile in VS 2017 and I want to know why not. Unless the answer IS "C++/CX projects don't compile without UWP", which I see no evidence for.
Step 1: Make new project.
Compile. Compiles fine.
Step 2: Turn on C++/General/Consume Windows Runtime Extension (/ZW). Turn off /Gm.
Compile.

Step 3: Ungh. Read up about it. Turn conformance mode = NO in C++ settings
Compile.

Step 4: Ungh. Read more online about finding the right paths. Set additional #using directories in C++ settings to:

$(WindowsSDKDir)UnionMetadata;

Compile.

Step 5: look up error online. Everything I look up is telling me I can’t mix UWP code with C++ native code or some such.
Am I missing something easy? This shouldn’t be so difficult, right?
