binding - Can't get .NET Policy DLL to redirect application to newer assembly -

my background in technical back upwards had resulted in me putting far much info in post, leading nobody beingness interested in reading it, imho, more info improve less.

there basic , fundamental assembly binding , redirection i'm missing. i'm trying create policy dll redirect applications have compiled against older version of assembly newest version. nil seems work. i've outlined steps take below. i'm not using visual studio, command line tools included .net framework , windows sdk. can tell me why, in step eleven, when run application compiled against v1.0.0 version of assembly, application not redirected towards v2.0.0 assembly registered in gac?

as follow along did, you'll have take note of directory i've executed commands in.

i more happy rtfm answer, if you'd kind point tfm i'm supposed read.

thanks in advance, reg

turns out whole problem day 1 lack of double quotes around :

culture=neutral

i alter .config file read

culture="neutral"

and worked charm. error in assembly binding debug outlog log indicated parse error in xml config file have been handy, , might have saved me 2 days. oh well.
