How to create a dialog result in maham?

I'm trying to create a code to show a dialog result:

var result = this.ShowMessageAsync("proceed?", "Info", MessageDialogStyle.AffirmativeAndNegative);
if (result == MessageDialogResult.Affirmative)
{
    this.Hide();
}

but the compiler on this line if (result == MessageDialogResult.Affirmative), show me this message:

you can not apply the == operator to operands of type 'Task ' and 'MessageDialogResult'

In some example it was used this operator, what I doing wrong?

ShowMessageAsync() seems to be an asyncronous method, meaning it returns a Task<T> instead of a T.

So you can either await the task like this:

var result = await this.ShowMessageAsync("proceed?", "Info", MessageDialogStyle.AffirmativeAndNegative);

Or you can get the Result of it:

var result = this.ShowMessageAsync("proceed?", "Info", MessageDialogStyle.AffirmativeAndNegative)
    .Result;

Not that if you want to await the task, you must be in a method marked async
