在上一个操作完成之前,在此上下文上启动了第二个操作。使用Linq Any()

我试图加快我的代码,所以我想看看我的代码可以多快,如果我做异步。

A second operation started on this context before a previous operation completed. 

现在我有这样的模式

TableATableB - many to many column
TableA - Can have many TableBs 
TableB - Can have many TableAs
TableC - TableB can have many TableCs and TableC can only have 1 tableB

现在我的代码死掉的问题是当我死掉的时候

foundTableBColumn.TableCs.Any()

var foundTableBs = dbContext.TableATableB Include(x => x.TableB).ThenInclude(x => x.TableC).Where(x => x.TableAId == 1).Select(x => x.TableA).ToList();


Parallel.ForEach(foundTableBs , (tableB, loopState) =>
                {
                      if(tableB.TableCs.Any(){
}
                });
