# Command line arguments for UWP

> Use command line arguments in your UWP application.

You can launch Unity Players from the command line and pass in arguments to change how the Player executes. Universal Windows Platform (UWP) apps don’t accept command line arguments by default, so you have to pass them to an AppCallbacks constructor in `App.xaml.cpp` or `App.cpp` to specify them.

This code example demonstrates how to do this:

```
m_AppCallbacks = 
    ref new AppCallbacks
    (
        ref new Platform::Array<Platform::String\^> 
        {
            L"-force-gfx-direct" 
        }
    );
```
