Asp Net Core CountAsync() on generic Iqueryable

Hello,

I keep getting this exception on Asp Net Core 1.1.0:

{System.InvalidOperationException: The provider for the source IQueryable doesn't implement IAsyncQueryProvider. Only providers that implement IEntityQueryProvider can be used for Entity Framework asynchronous operations.
at Microsoft.EntityFrameworkCore.EntityFrameworkQueryableExtensions.ExecuteAsync[TSource,TResult](MethodInfo operatorMethodInfo, IQueryable`1 source, CancellationToken cancellationToken)
at Microsoft.EntityFrameworkCore.EntityFrameworkQueryableExtensions.CountAsync[TSource](IQueryable`1 source, CancellationToken cancellationToken)
at CoreWebTemplate.PaginatedList`1.<CreateAsync>d__13.MoveNext() in C:\Users\littl\Source\Workspaces\Workspace\Jumanji\CoreWebTemplate\src\CoreWebTemplate\PaginatedList.cs:line 42}

it occurs with the CreateAsync await tasks that im using in PaginatedList.cs.  ive mixed in some task.delays but frankly im at a loss

Code below. Thank you
