The Xbox Live Unity Plugin provides a way for developers in the Xbox Live Creators Program to quickly and easily integrate Xbox Live functionality into their Unity based game. For ID@Xbox developers, this Xbox Live Unity Plugin does not yet support all the features you will need. Instead, contact your Microsoft representative.
Unity: 5.6.3f1 I downloaded the plugin(1804), Crash sometimes when call following code:
StartCoroutine(SignInManager.Instance.SignInPlayer(1));
