"Compile" button doesn't save Visual Studio files

I tried this even by creating a brand new project from scratch… the issue persists.

I click the Compile button in the Editor but, in Visual Studio, the file MyClass.cpp (or any other file) DOESN’T GET SAVED

This means that Unreal is technically compiling always the same thing, without saving the source code that I modify through Visual Studio.

I tried also changing the Visual Studio version in the Editor Preference: no luck.

Whatever version I choose (2015, 2017) the issue persists…

Have the same problem. Probably related to the bug is that UE keeps showing “Loading Visual Studio” long after VS has started and then eventually opens up a 2nd instance of VS.

YES! Exactly! This new version of the Engine is creating a mess with Visual Studio!
