Modify the version information of a built .NET ass

Question

Is there a better way to modify the version information of a .NET assembly of the one I am currently using.

My current approach is the following.

I do disassemble the assembly with ildasm:

ildasm /nobar Riolo.WebUI.dll /out=Riolo.WebUI.il 

This will generated also a Riolo.WebUI.res compiled resource file, that I then open and modify with the user interface of Visual Studio, then I do reassemble the assembly back with ilasm:

ilasm Riolo.WebUI.il /OUTPUT=Riolo.WebUI.dll /RESOURCE=Riolo.WebUI.res /DLL /PDB 

There are various issues with this process, the main is obviously that I feel like shooting at a mosquito with a broadside of carronades, then that as I don't know how decompile .res files to .rc files with the command line, I cannot use a command line script, as I have to open Visual Studio to modify the .res file, which means it is very time consuming and somewhat error prone, and, last but not least, I do feel that roundtripping assemblies I may well end up loosing information, even if unwittingly, hence I am afraid I will early or later be bitten in some yet unforeseen scenario.
