Castle.DynamicProxy and Assemblies

[Brian Elcock]

I'm new to this. Please forgive me. It doesn't seem to matter what
reference I have where -- I continue to get the error. What would cause
this:

The located assembly's manifest definition with name
'Castle.DynamicProxy' does not match the assembly reference.
Description: An unhandled exception occurred during the execution of
the current web request. Please review the stack trace for more
information about the error and where it originated in the code.

Exception Details: System.IO.FileLoadException: The located assembly's
manifest definition with name 'Castle.DynamicProxy' does not match the
assembly reference.

                                       id = #value#

                       </dynamic>
               </select>

Thanks for any insight.
