So your POCO is acting as a base type for the Entity Framework's dynamically created subclasses. That's what I meant by "create a proxy around...

What is the exact problem with multiple inheritance?
...ects in memory.
Languages like C++ and Java and C# create a fixed address-based layout for each type of object. Something like this:
class A:
at offset 0 ... "abc" ... 4 byte int field
