嗨Sukanya Karri，

我不知道您是否还在寻找答案.

我也不知道您是否将问题发布在正确的位置.也许您应该在linq问题下尝试.

但是，我可以说的是，您不能将来自两个不同上下文的数据放在一起.

Hi Sukanya Karri,

I don''t know if your still looking for an answer on this.

I don''t know as well if you posted your question in the right place. Maybe you should try under linq questions.

But, what I can say by the way, is that you can''t put together data from two different contexts.

You can follow the link below for more details:
