I can't compile from Visual Studio

Hi everyone,
I’m using VS2017 with the 4.15 editor and there is something which is not working fine : whenever I try to build from VS, I have this error :

BUT, if I compile it in unreal, there is no problem. And then if I try build in VS, everything works fine, until I edit something and I rebuild it.

I tried to delete Unreal Derived files, but it does not solved the problem, and things are even worse now : I can’t acces my project anymore in VS, it say “failed to load”.

Thank you !

To recover your project files you can press right mouse button on your project file and run “Generate Visual Studio project files”.

For those who have the same kind of problem, it mostly is because you did something wrong with pointers. The way you recover you’re project is really simple :
Undo the changes you made before the crash occurs (especially things with pointers involved)
Delete the Binairies, Intermediate and Saved folder from the root directory of your project
Right clic the “YourProject.uproject” file and clic on Generate Visual Studio project file.
Open you’re project and say yes to rebuild.
And everything sould be fine !
