My website is developed in ASP and I want to use word press with it for blog posting. Is it ok to use it ASP website or there is WP version available in ASP?
There's no particular reason that you can't have your site in ASP and the blog in PHP. You can use PHP in a windows environment. Heck, you could even do an A-Record for a subdomain point it to a completely different machine to host your blog if you wanted to. You could also buy hosting at typepad or wordpress and map your A-Record-forwareded subdomain to it. Lots and lots of options.
