Assembly attribute issue

[william]

Hi, everyone,
I'm using VB.NET to developing COM+. THere are a few classes under one
project. when I compile it, I got error
"System.EnterpriseServices.ApplicationNameAttribut e' cannot be specified more
than once in this project, even with identical parameter values.", and
warning "Warning: The dependency 'ADCDataAccess, Version=1.0.1790.31794,
Culture=neutral, PublicKeyToken=14c45b235ab55f19' in project 'ADCAsset'
cannot be copied to the run directory because it would overwrite the
reference 'ADCDataAccess, Version=1.0.1829.30525, Culture=neutral,
PublicKeyToken=54d11f9b3b7371b9'.". Sometimes I got error about strong name
"Couldn't find path of adc.snk" even though the file exists there.
What could be the problem?
Note: I put a few <Assembly: ....> statements in each class, some of them
are same. Even I put AssemblyKeyFileAttribute in each class with same file
name. Is that ok? Basically, what kind of attribute should I put in class,
and what kind of attribute should I put in AssemblyInfo?
Thanks.
