LINQ 表达式中的 OData $top 查询无法转换，将使用 EF Core 和 .NET Core 2.2 在本地进行评估

Question

I have an OData endpoint in my .NET Core API:

[EnableQuery]
[ODataRoute]
[HttpGet]
public IQueryable<MerchantDto> GetAll()
{
    return _context
        .Merchants
        .Where(x => !x.IsDeleted)
        .ProjectTo<MerchantDto>(_mapper.ConfigurationProvider);
}

It generates an SQL without LIMIT statement (postgres db) and this warning appears:

The LINQ expression 'Take(__TypedProperty_1)' could not be translated and will be evaluated locally.

How can I make this query to DB to include the OData $top ? It is always getting the whole table records first.

Answer 1

I had a wrong object mapping configuration that caused that problem.
