EF Core 3.1.0 - Method not found: 'System.Collections.Generic.IEnumerable`1

Hi All,

When I'm deploying windows services using EF 3.1.0, the following error has occurred while executing the Linq Query. and it's working perfectly in my local machine, the issue happens while deploying in the windows server 2012 R2.

.Net framework 4.6.1
EF CORE 3.1.0

using (var ctx = new DatabaseContext())
{
var bats = (from bt in ctx.Batches
where bt.Is_Active == true && bt.Is_Completed == false && bt.Is_Locked == false
select new
{
bt.Batch_Id,
bt.Batch_No
}).ToList();

Error:
