Asynchronous Programming Design Goals and Improvements Covers how the Microsoft Game Development Kit (GDK)‘s new asynchronous programming model was designed and the improvements made as a result of developer feedback regarding the XBOX One ERA async model. Asynchronous Programming Model Provides information about how the Microsoft Game Development Kit (GDK) implements a new pattern for asynchronous APIs. This topic describes this design pattern and offers a proposal for a library that can be used to implement asynchronous patterns. Async task queue design Describes the Microsoft Game Development Kit (GDK) task queue that’s used in conjunction with the Microsoft Game Development Kit (GDK) async design pattern. A task queue is an API for queuing work and completion task callbacks. Task queue can be configured in one of several different dispatch modes, including a manual dispatching mechanism that you can use when you want to carefully manage gaming workloads. Additionally, this section provides how-to examples for common async task queue scenarios. XTaskQueue Library Overview Describes the purpose and usage of the XTaskQueue library and has example topics to walk through the basic usage. XAsync Library Overview Describes the purpose and usage of the XAsync library and has example topics to walk through the basic usage. XAsyncProvider Library Overview Describes the purpose and usage of the XAsyncProvider library and has example topics to walk through the basic usage. Generic Async Task Wrapper Provides an implementation of a generic async task wrapper function that can be used to simplify the process of running generic user tasks asynchronously using the Microsoft Game Development Kit (GDK) asynchronous programming model.
