I've got thumbs down for messing up with windows registry from my friends, saying mostly they replace an assembly and do not expect to remove registry information as next thing to removal of assembly is installation of latest one into GAC for them.
But nobody can stop me giving next version of GAC browser. I've got a 'good' idea about integrating Native Image Compilation through/with GAC Browser itself.
Presently there is no way you can see if you dearly assembly is Natively Compiled or not. I think it would be nice to represent that in GAC Browser search result :)
