Hi am using Firebasedatabase.net V 4.0.5 in Xamarin Forms

I am able to insert update records very fast but while ferching single recrod it is taking above 6 sec

This is my code:

var pricelist = Task.Run(async () =>

(await firebase.Child("Price").OnceAsync())

.Where(L => L.Key == key

).ToList()

).Result;

this is happening only in Xamiarn.Forms, Any one please help on this

One of the author has written crud operation with firebase, have a look https://www.c-sharpcorner.com/article/xamarin-android-working-with-firebase-database-part-two/

I think it might be issue using linq, have you tried fetching without where and SingleOrDefault condition and observe the time fetched by the OnceAsync function.

FirebaseClient firebase = new FirebaseClient(myURL);
var pricelist = (await firebase.Child("Price").OnceAsync())
.Where(L => L.Key == "-MS2bswGJj5Iy4irEC1h")
.SingleOrDefault();
if (pricelist != null)
{
}

Am runnung above code but result is same... It is taking 10 sec

Instead of using .Result at the end to wait for the result, try using await keyword at the beginning.
