/// <returns> A read-only collection of the available devices on the platform. </returns>
/// <remarks> This method resets the <c>ComputePlatform.Devices</c>. This is useful if one or more of them become unavailable (<c>ComputeDevice.Available</c> is <c>false</c>) after a device and command queues that use the device have been created and commands have been queued to them. Further calls will trigger an <c>OutOfResourcesComputeException</c> until this method is executed. You will also need to recreate any <see cref="ComputeResource"/> that was created on the no longer available device. </remarks>
