A word of caution for 4.18 (.1) users

[Sotem]

I want to share this post to prevent issues for other students.
While I was working in 4.18 I updated to 4.18.1, since I did this I have had a bug that halted
my progress.
Eventually I even had to delete the entire project and migrate back to 4.17.

Since 4.18.1 every time I doubleclick on a C++ class in UE4, visual studio opens but
the “loading visual studio” balloon doesn’t dissapear.

This is a known bug and should be resolved in 4.19

I tried unistalling and reinstalling 4.18.1 which didn’t work.
Also reinstalling VS2017 or 2015 didn’t resolve the problem.

If you wish to avoid going through an entire week of trial and error, please refrain using
4.18.1 for now.

I wasn’t sure where to post this, so if this is faulty posted I think Sam will resolve this!

Thanks for sharing this. Hopefully they will find a fix before 4.19. Any workarounds till then?

There is a somewhat hacky workaround.
So personally I would recommend sticking to 4.17.2 for now.

Nonetheless, for those interested:
When you start the uProject and double click on an item it opens visual studio (and then the loading visual studio loops).
Then you close the project (but keep VS opened),
And reopen the project.
Now when you edit code in VS you can use compile and build just like you normally would.
However double clicking on a .cpp file in the engine will make the bug active again.

WARNING: While this does seem to work, I’ve had 2 cases of the project being unworkable.
I would start the project and it then states that the files are from a different version and it then ask to rebuild the source.
This didnt work in the engine and it didnt work doing this process manualky in vs2017 and 2015 tested.
Thus rendering me unable to open the project causing me to start from scratch.

It might be able to still get it to work, but I found that in the hours that I spent trying to fix this, I could’ve remade the project several times.
