.NET Fiddle

Console app

    using System;
    using System.Linq;

    using Community.OData.Linq;

    public class Entity
        public int Id { get; set; }

        public string Name { get; set; }

    public static class GetStartedDemo
        public static void Demo()
            Entity[] items =
                    new Entity { Id = 1, Name = "n1" },
                    new Entity { Id = 2, Name = "n2" },
                    new Entity { Id = 3, Name = "n3" }
            IQueryable<Entity> query = items.AsQueryable();

            var result = query.OData().Filter("Id eq 1 or Name eq 'n3'").OrderBy("Name desc").TopSkip("10", "0").ToArray();

            // Id: 3 Name: n3
            // Id: 1 Name: n1
            foreach (Entity entity in result)
                Console.WriteLine("Id: {0} Name: {1}", entity.Id, entity.Name);

Support ToArrayAsync(), ToListAsync(), and all other provider specific methods.

Use .ToOriginalQuery() after finishing working with OData to be able to support provider specific methods of original query.

Entity Framework async data fetch.

Student[] array = await dbContext.Students.OData()
                .Filter("LastName eq 'Alexander' or FirstMidName eq 'Laura'")
                .OrderBy("EnrollmentDate desc")
                .ToOriginalQuery() // required to be able to use .ToArrayAsync() next.

ISelectExpandWrapper[] select2 = await dbContext.Students.OData()
                .Filter("LastName eq 'Alexander' or FirstMidName eq 'Laura'")
                .OrderBy("EnrollmentDate desc")
                .SelectExpandAsQueryable("LastName", "Enrollments($select=CourseId)") //.SelectExpandAsQueryable() use .ToOriginalQuery() implicitly, so not need to call it.

CosmosDb SQL API async data fetch.

var item = await Container.GetItemLinqQueryable<TestEntity>().OData()
                .Filter($"Id eq '{id1}'")
                .ToOriginalQuery() // required to be able to use .ToFeedIterator() next.

Significant improvement in query initialization performance. Support ToArrayAsync(), ToListAsync(), and all other provider specific methods. More integration tests for Entity Framework and CosmosDb SQL API. Breaking Changes: net4.5 not suported anymore. Obsolete methods removed (.SelectExpandJsonToken() and .SelectExpandJson()). Setting for default timezone in case of converting DateTimeOffset to DateTime
