Cannot assign method group to an implicitly-typed local variable

Question

I have this error

"Cannot assign method group to an implicitly-typed local variable"

in this code

private async void Button_Click_2(object sender, RoutedEventArgs e)
{
    var frenchvoice = InstalledVoices.All.Where(voice => voice.Language.Equals("fr-FR") & voice.Gender == VoiceGender.Female).FirstOrDefault; // in this line
    sp.SetVoice(frenchvoice);
    await sp.SpeakTextAsync(mytxt);
}

Answer 1

You forgot to call the function (with ())

Answer 2

You must add the round brackets to call the method FirstOrDefault

   var frenchvoice = InstalledVoices.All
       .Where(voice => voice.Language.Equals("fr-FR") && 
                       voice.Gender == VoiceGender.Female)
       .FirstOrDefault();

And, while your code works also using the & operator, the correct one to use in a logical condition is &&

By the way, FirstOrDefault accepts the same lambda applied to Where so you could reduce your code to a simpler and probably faster

   var frenchvoice = InstalledVoices.All
       .FirstOrDefault(voice => voice.Language.Equals("fr-FR") && 
                                voice.Gender == VoiceGender.Female);
