entity framework 4 - Can't use code generators because of "object reference not set to an instance of..." -

What could be the reason for this behavior?

I get the ADO.NET EntityObject / Poco / SelfTracking generator and I am not only set to "an example of object reference object" error

I can add the Oracle Provider I have been using EF4 and I have already prepared the code with AdamGen 2, but right now I am present. I would like to generate POCO classes from the AMMX file which was made above the existing database.

I have never used this feature, but you can see exception stacks / internal exceptions It can help you track the exception source so that it can be easier for users.

Or maybe it's a broken relationship or maybe some line of your Patial-Class constructor or other function is throwing this error.
