search .net framework
but you can only run .net application. you must get .net framework sdk to dev .net app.
i suggest you that install a vs.net2003,and then,you will have all tools required for .net
you can read the file(i foget the name),2000 or advancer WIN OS is supported.of course you must have IIS installed...
good luck.vs.net IDE is the best tool to dev .net app.
