Efcore uses asynchronous query error: The source IQueryable doesn’t implement IDbAsyncEnumerable

1. Asynchronous query error:

return dc.table.ToListAsync();

F12 enters the ToListAsync method (before removing the Entityframework package)


After removal


It can be seen that different assemblies are used.
