Recently, I got a chance to migrate my project from vs2003 to vs2005, I got some trouble when I tried to upgrade my llblgen data assembly from .net 1.1. to .net 2.0 assembly.

The problem is I was using the EntityCollectionBase2 in the old project, but I found it's not supported under the .net 2.0 because it's changed to a generic class.

Is this TRUE? If it's this, that means I can not upgrade this assembly to .net 2.0 which is VERY sad for me.....

Can anyone help me at this point?

try using IEntityCollection2 instead.

Is this the only way to play around it? If it is, then that means I can not upgrade the project.

see this similar thread:

there's also a Migrating your code section in the official documentation, migrating your code is very straightforward for the majority of cases, let us know if you hit a wall.

Change code using ENtityCollectionBase2 to IEntityCollection2 You then can keep on using the same code and have all the features at hand.
