实体框架7联合查询错误

Question

此查询适用于EF6：

var ids = new int[] { 1, 2, 3 };
var consultants = _dbContext.Times
    .Where(t => ids.Contains(t.MilestoneId))
    .Select(t => t.Consultant)
    .Union(
        _dbContext.TimeBudgets
            .Where(tb => ids.Contains(tb.MilestoneId))
            .Select(tb => tb.Consultant)
     );

在EF7中，我收到错误：

An unhandled exception occurred while processing the request.
