Upgrading a code project from 4.8 to 4.9 results in the startup project in the Visual Studio solution changing from the game project to the UE4 project.

Upgrading a code project from 4.8 to 4.9 results in the selected startup project in the Visual Studio solution changing from the game project to the UE4 project. This results in unexpected behavior if the user upgrades a project, opens the solution, and attempts to immediately launch the project through the debugger.

If the binary engine is being used, Visual Studio will display an error message stating that it cannot find the UE4.exe file. If the engine was built from source code, the project browser window will open and selecting a project to open will open the Editor in a new Windows process and stop the debugger process.

1. Create a new code project in version 4.8 using the first person template.
2. Build the project in Visual Studio.
   • Note that the game project is selected as the startup project.
3. Upgrade the project to 4.9 by creating a copy of the project.
4. Open the upgraded project in Visual Studio.

RESULT:
The upgraded project in Visual Studio shows the UE4 project as the startup project instead of the game project.

EXPECTED:
The upgraded project in Visual Studio keeps the startup project the same as it was in the previous version.

I cannot launch in Debug
