Hi LTE,

I just wanted to clarify this for you, and anyone else who reads this question.

When you build a project in Visual Studio, the project will not run automatically when it is finished building. For code projects, building the project in Visual Studio is critical, as the project will not open in the Unreal Editor at all if it has not been successfully built. Once it is built, you have a few options to actually open the project in the Editor.

  1. Run the project in Visual Studio, either with or without debug. You can do this by pressing F5 in Visual Studio (to run with debugging) or Ctrl-F5 (without debugging). My preference though is to right-click on the project name in the Solution Explorer and go to Debug → Start new instance.
  2. Locate the .uproject file for your project and double-click it to open the project in the Editor.
  3. Open the Editor, find your project in the Project Browser window, and open it from there.

If you have built your project successfully in Visual Studio, any of these options will work to open your project in the Editor. Things may get a bit confusing if you have multiple versions of the Engine installed, though.

To add to answer, I had the problem where I was pressing F5 in Visual Studio but the editor wasn’t launching. Turned out I had an Unreal Editor still there in my task manager. I killed the process, hit F5 and it worked. (Unreal 4.22.1)
