This is an add-in for Fody

Adds support for save the state of asynchronous tasks for WP and WinRT platforms. Updates all IAsyncStateMachine in the code so that they passed itself to the IAsyncStateMachineAware interface.

Your Code

[CompilerGenerated]
[StructLayout(LayoutKind.Auto)]
private struct <TestMethod>d__0 : IAsyncStateMachine
{
	public int <>1__state;
	public AsyncVoidMethodBuilder <>t__builder;
	private object <>u__$awaiter1;
	private object <>t__stack;
	void IAsyncStateMachine.MoveNext()
	{
		try
		{
			int num = this.<>1__state;
			IAsyncOperationAwaiter<bool> asyncOperationAwaiter;
			if (num != 0)
			{
				asyncOperationAwaiter = Program.Get().GetAwaiter<bool>();
				if (!asyncOperationAwaiter.IsCompleted)
				{
					this.<>1__state = 0;
					this.<>u__$awaiter1 = asyncOperationAwaiter;
					this.<>t__builder.AwaitOnCompleted<IAsyncOperationAwaiter<bool>, Program.<TestMethod>d__0>(ref asyncOperationAwaiter, ref this);
					return;
				}
			}

			{
				asyncOperationAwaiter = (IAsyncOperationAwaiter<bool>)this.<>u__$awaiter1;
				this.<>u__$awaiter1 = null;
				this.<>1__state = -1;
