We use svn revision for the ProductBuildPart of our FileVersionInfo . Because we're above revision 65536, we had to mod the number. To compensate, we stick the real number in the AssemblyInformationalVersionAttribute. This is easy enough when we build the assemblies from source.
However, we have an assembly generated by SGen for performance. Is there an easy way to change/add an AssemblyInformationalVersionAttribute on an already built assembly?
