Question

I’m using VS2010, and I’ve download the C# POCO Entity Generator and installed it, now I want to use it.

I can’t read the toturial ¹ and I can’t find any other good toturials, so I’ve had a go myself – I have created a model and then I’m creating new POCO Entity, but I got the bellow error:

Error 1 Running transformation: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.IO.FileNotFoundException: Unable to locate file

What is the problem? I think it can’t find the model mapping, if this is the case, how do I resolve this?

Check this article for error description and how to deal with it. It is problem of path substitution when creating POCO template from Add item in Visual Studio.
