I've been working on a C# MonoGame project for a few days now and so far it has been building and running fine. I left it alone for a while and, when I came back, the window would no longer display (running as a console application displays a blank console window, but not the application itself).
I don't think it's due to the code itself because the issue started happening without any changes to it.
When building, the program exits with code -1, as shown below in the output:
The program '[12460] Gearworks Physics Engine.exe' has exited with code -1 (0xffffffff).
Note that building the program gives no errors, warnings, or messages.
I realise there are a lot of posts related to "exited with code _" and I have seen some with code -1, but they weren't very helpful to my situation, so I've decided to post my own question instead. Let me know if there's any other information needed to help!
Solved - I simply needed to update Visual Studio to the latest version, which I was apparently not using. Once I did that, all programs worked again.
