错误：v6.1.3（& v6.1.2）：延迟LINQ执行（/多语句）错误

问题描述

Guys& Gals，除非我不理解EF工作/应该如何工作的微妙之处，当你在单独的C＃-statements中分解LINQ查询时，你似乎有v6.1.3的错误;例如这是有效的：
$


            var fullQry =

                dbCtx.BldAs.AsNoTracking（）。ToList（）;

Guys & Gals, unless I don't understand a subtlety of how EF works/should work, you seem to have a bug with v6.1.3, when breaking-up LINQ queries across separate C#-statements; e.g. this works:

            var fullQry =
                dbCtx.BldAs.AsNoTracking().ToList();

但这会引发异常：

But this throws an exception:

            var qry =

                （IQueryable< BldA>）dbCtx.BldAs;

            var qry =
                (IQueryable<BldA>)dbCtx.BldAs;

推荐答案

根据您的描述，我遇到类似问题，似乎是一个实体框架6.1.3问题，我可以建议你可以将你的实体框架版本升级到6.2.0。这是实体框架中最重要的变化
6.2.0。
