Sequence contains no elements at 5.0.0-alpha

Every operation with collection throw System.InvalidOperationException.

Framework: Xamarin.Forms Platform: Android OS Library Version: 5.0.0-alpha

Code to reproduce:

var db = new LiteDatabase("database.db"));
var collection = db.GetCollection<T>("exampleColleciton");
var allElements= collection.FindAll();

Also Insert, Delete, Find will throw System.InvalidOperationException: Sequence contains no elements StackTrace:

I ran into the same problem. It only occurs when I create the database completely new (0kB file). The Exception is thrown on LiteDatabase db = new LiteDatabase(liteDbPath). It can however be opened by the LiteDB Studio. I solved the problem by simply downgrading to 4.1.4.

yeah that was the problem, i fixed it by deleting the file creation:

        public string GetDatabasePath()
        {
            var path = Path.Combine(_appData, "ZAsetMobile.db");

            //if (!File.Exists(path))
            //{
            //    using (var streamWriter = new StreamWriter(File.Create(path))) ;
            //}

            return path;
        }

Many thanks for your help! kind regards, bluekuen
