Hi!

Im having an issue, my code is working but im thinking in long terms.

Right now I have this method:

        private async Task<bool> ValidateRecurrentEventExecution()
        {
            try
            {
                var recurrentEventsExecutions = await _recurrentEventExecution.GetAllListAsync();
                foreach (var recurrentEventsExecution in recurrentEventsExecutions)
                {
                    if (DateTimeToString(recurrentEventsExecution.StartDate) == DateTimeToString(DateTime.Now))
                        return true;
                }

                return false;
            }
            catch (Exception e)
            {

                throw e;
            }
        }

And everything works fine but when in a few months or year this could return a lot of items in the list.

var recurrentEventsExecutions = await _recurrentEventExecution.GetAllListAsync();

So Im trying to do something like:

var recurrentEventsExecutions = await _recurrentEventExecution.GetAllListAsync().orderByDecending(x => x.Id).take(20);

But IRepository doesn have this methods

namespace Abp.Domain.Repositories
{
    public interface IRepository<TEntity, TPrimaryKey> : IRepository, ITransientDependency where TEntity : class, IEntity<TPrimaryKey>
    {
        int Count();
        int Count(Expression<Func<TEntity, bool>> predicate);
        Task<int> CountAsync(Expression<Func<TEntity, bool>> predicate);
        Task<int> CountAsync();
        void Delete(TEntity entity);
        void Delete(TPrimaryKey id);
        void Delete(Expression<Func<TEntity, bool>> predicate);
        Task DeleteAsync(TPrimaryKey id);
        Task DeleteAsync(Expression<Func<TEntity, bool>> predicate);
        Task DeleteAsync(TEntity entity);
        TEntity FirstOrDefault(Expression<Func<TEntity, bool>> predicate);
        TEntity FirstOrDefault(TPrimaryKey id);
        Task<TEntity> FirstOrDefaultAsync(Expression<Func<TEntity, bool>> predicate);
        Task<TEntity> FirstOrDefaultAsync(TPrimaryKey id);
        TEntity Get(TPrimaryKey id);
        IQueryable<TEntity> GetAll();
        IQueryable<TEntity> GetAllIncluding(params Expression<Func<TEntity, object>>[] propertySelectors);
        List<TEntity> GetAllList(Expression<Func<TEntity, bool>> predicate);
        List<TEntity> GetAllList();
        Task<List<TEntity>> GetAllListAsync(Expression<Func<TEntity, bool>> predicate);
        Task<List<TEntity>> GetAllListAsync();
        Task<TEntity> GetAsync(TPrimaryKey id);
        TEntity Insert(TEntity entity);
        TPrimaryKey InsertAndGetId(TEntity entity);
        Task<TPrimaryKey> InsertAndGetIdAsync(TEntity entity);
        Task<TEntity> InsertAsync(TEntity entity);
        TEntity InsertOrUpdate(TEntity entity);
        TPrimaryKey InsertOrUpdateAndGetId(TEntity entity);
        Task<TPrimaryKey> InsertOrUpdateAndGetIdAsync(TEntity entity);
        Task<TEntity> InsertOrUpdateAsync(TEntity entity);
        TEntity Load(TPrimaryKey id);
        long LongCount(Expression<Func<TEntity, bool>> predicate);
        long LongCount();
        Task<long> LongCountAsync();
        Task<long> LongCountAsync(Expression<Func<TEntity, bool>> predicate);
        T Query<T>(Func<IQueryable<TEntity>, T> queryMethod);
        TEntity Single(Expression<Func<TEntity, bool>> predicate);
        Task<TEntity> SingleAsync(Expression<Func<TEntity, bool>> predicate);
        TEntity Update(TEntity entity);
        TEntity Update(TPrimaryKey id, Action<TEntity> updateAction);
        Task<TEntity> UpdateAsync(TPrimaryKey id, Func<TEntity, Task> updateAction);
        Task<TEntity> UpdateAsync(TEntity entity);
    }
}

    Seems to be your spelling mistake OrderByDescending

    https://docs.microsoft.com/en-us/dotnet/api/system.linq.enumerable.orderbydescending?view=netframework-4.7.2

    If you want to use database paging, please use IQueryable
