WinRT API in C# scripts for UWP

Use WinRT API directly in Unity scripts for UWP.
Read time 1 minuteLast updated 11 days ago
Unity includes Windows Runtime (WinRT) support when building for Universal Windows Platform with the IL2CPP scripting backend. Use Windows Runtime support to call into both native system Windows Runtime APIs as well as custom .winmd files directly from managed (C#) scripts and plugins.
Unity automatically references Windows Runtime APIs such as 
Windows.winmd
on Universal Windows Platform. To use custom .winmd files, import them into your Unity project folder together with any accompanying DLLs and configure them. For more information, refer to Import and configure plug-ins.
To use WinRT API in your Unity scripts:
  • Your scripts must be written in C#.
  • All the code that uses WinRT API must be under the 
    ENABLE_WINMD_SUPPORT
    directive. This is necessary because the Editor uses Mono, which doesn't support WinRT APIs.
The following code example gets an advertising ID using WinRT API directly:
using UnityEngine;public class WinRTAPI : MonoBehaviour{    void Update()    {        auto adId = GetAdvertisingId();        // ...    }    string GetAdvertisingId()    {        #if ENABLE_WINMD_SUPPORT            return Windows.System.UserProfile.AdvertisingManager.AdvertisingId;        #else            return "";        #endif    }}
