Development Programming & Scripting Blueprint

I looked for solutions on the net, someone says that it is caused by not compiling c++ in VS. Probably!! While, how could I do now? There is no net.sln generated, how could I rebuild it manually?

Restore from backups. Or copy your project files now, reinstall (or fix) unreal and VS.

Compile it in visual studio so that you can actually see the errors. Right-click on the project file and select generate Visual Studio project and compile it from there
