How to use the AsyncCommand helpers:

AsyncCommand: (without parameters)

private IAsyncCommand test1;
public IAsyncCommand Test1 => test1 ??= AsyncCommand.Create(async () => {
  await Task.CompletedTask;
});

private IAsyncCommand test2;
public IAsyncCommand Test2 => test2 ??= AsyncCommand.Create(async token => {
  await Task.CompletedTask;
});

private IAsyncCommand test3;
public IAsyncCommand Test3 => test3 ??= AsyncCommand.Create(async (token, manual) => {
  await Task.CompletedTask;
});

AsyncCommand: (with parameters)

private IAsyncCommand test1;
public IAsyncCommand Test1 => test1 ??= AsyncCommand.Create<Data>(async data => {
  await Task.CompletedTask;
});

private IAsyncCommand test2;
public IAsyncCommand Test2 => test2 ??= AsyncCommand.Create<Data>(async (data, token) => {
  await Task.CompletedTask;
});

private IAsyncCommand test3;
public IAsyncCommand Test3 => test3 ??= AsyncCommand.Create<Data>(async (data, token, manual) => {
  manual.WaitOne();
  if (token.IsCancellationRequested) return;
  await Task.CompletedTask;
});

AsyncCommand: (return a completed task)

private IAsyncCommand test1;
public IAsyncCommand Test1 => test1 ??= AsyncCommand.Create(() => {
  return Task.CompletedTask;
});


AsyncCommand: (Check if we need to cancel the command)
private IAsyncCommand test4;
public IAsyncCommand Test4 => test4 ??= AsyncCommand.Create(async token => {
  if (token.IsCancellationRequested) return;
  await Task.CompletedTask;
}, true);

Binding for XAML:

<StackLayout>
  <Label Text="Command Result:" />
  <Label Text="{Binding Test1.Execution.Result}" />
  <Label Text="{Binding Test1.Execution.IsCompleted}" />
  <Label Text="{Binding Test1.Execution.IsNotCompleted}" />
  <Label Text="{Binding Test1.Execution.IsCompletedSuccessfully}" />
  <Label Text="{Binding Test1.Execution.IsCanceled}" />
  <Label Text="{Binding Test1.Execution.IsFaulted}" />
  <Label Text="{Binding Test1.Execution.ErrorMessage}" />
  <Button Command = "{Binding Test1}" CommandParameter="ThisIsATest">Test</Button>
  <Button Command = "{Binding Test1.CancelCommand}">Cancel</Button>
  <Button Command="{Binding Test1.ManualResetAsyncCommand}">Create Timeout</Button>
  <Label Text = "{Binding Test1.IsSuspend}" />
</StackLayout>
