.net-3.5

Hi all

I am converting an ASP.Net 2.0 Project to compile for .Net Framework 3.5 and facing the following compiler error for assembly reference...

InternalXmlHelper.vb(9,0): error BC30560: 'ExtensionAttribute' is ambiguous in the namespace 'System.Runtime.CompilerServices'.

It appears that there are duplicate assembly references one from 2.0 and the other from 3.5 but i have double checked it and its not the issue..

I have also googled around...with no success..

I have sure that i am doing some tiny mistake in additiona or removal of references,,,Is there any special thing that needs to be checked or done when compiling asp.net 2.0 project under .Net Framework 3.5 ?

Kindly help.

Thanks

Regards
