async void DemoMethodAsync(CancellationToken token) {
    await Task.Run(() => { DemoMethodSync(); }, token).ConfigureAwait(false);
}

Async Sub DemoMethodAsync(token As CancellationToken)
    Await Task.Run(Sub() DemoMethodSync(), token).ConfigureAwait(False)
End Sub

async void DemoMethodAsync(CancellationToken token) {
    try {
        await Task.Run(() => { DemoMethodSync(); }, token).ConfigureAwait(false);
    } catch(Exception ex) {
        Console.WriteLine(ex);

}

Async Sub DemoMethodAsync(token As CancellationToken)
    Try
