The operation cannot be completed because the DbContext has been disposed

I use abp 2.0.2. The exception as follow:

The operation cannot be completed because the DbContext has been disposed.
   在 System.Data.Entity.Internal.LazyInternalContext.InitializeContext()
   在 System.Data.Entity.Internal.Linq.DbQueryProvider.System.Data.Entity.Infrastructure.IDbAsyncQueryProvider.ExecuteAsync[TResult](Expression expression, CancellationToken cancellationToken)
   在 System.Data.Entity.QueryableExtensions.CountAsync[TSource](IQueryable`1 source, CancellationToken cancellationToken)
   在 System.Data.Entity.QueryableExtensions.CountAsync[TSource](IQueryable`1 source)
   在 ZTO.UserAnalysis.UserInformation.UserInformationAppService.<SyncDataFromOrder>d__4.MoveNext() 位置 E:\ztoSource\UserAnalysis\ZTO.UserAnalysis.Application\UserInformation\UserInformationAppService.cs:行号 45

In application method, I set UnitOfWork`s IsDisabled to true, and i call repository in the method.

My code is bellow:

 [UnitOfWork(IsDisabled = true)]
		public async Task SyncDataFromOrder(DateTime from, DateTime to)
		{
			var orderQuery = _orderRepository.GetAll().Where(i => i.CreationTime >= from && i.CreationTime <= to).OrderBy(i => i.CreationTime);
			var querySize = await orderQuery.CountAsync();

		}

I see. It need’s to be virtual, or injected using the interface version. I think that is what I have been missing then. Thanks @acjh!
