You get, which error? What is the type of the error, message etc.

Basically it can be saved to multiple databases, tables or even networks. But the error would hold specific information.

Solution 1

You cannot attach a single entity object to multiple contexts and have all those contexts cooperate with each other. They don't know about each other at all.

The only way to make this work is to have one copy of each entity object for each context. In your example, you need five copies of your "TheRec1" object, one for each context that is working with each of your databases.

that is hard, because I have another tables which are have too many properties. that will make the code very long
