Method 'System.Object DynamicInvoke(System.Object[])' has no supported translation to SQL?

Change Func to Expression. Right now, because of this, EF doesn't understand it.

Thanks for your answer ^^ – ByulTaeng Jun 5 at 11:09 I've changed it according to your suggestion but got another error 'idProperty' is a 'variable' but is used like a 'method' – ByulTaeng Jun 5 at 16:09 I'm sorry. I cant help you. Query composition can be ass sometimes and this looks like it won't be easy to implement.

One thing that comes to mind is to create the expression tree by hand. But I don't have time for that. – Euphoric Jun 6 at 6:04.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
