6. To check when resources are ready, we use a new ResourcesReady flag as shown

in following code snippet:
bool ResourcesReady = false;
protected async override void
CreateDeviceDependentResources(Common.DeviceManager
deviceManager)
{
ResourcesReady = false;
...
ResourcesReady = true;
}
public override void Render()
{
if (!ResourcesReady)
return;
var context = this.DeviceManager.Direct3DContext;
...
}
