I found several versions of an IIS-free Cassini webserver built by Microsoft. I\'d use it but I\'m unsure of which one is best, since there are many forks/builds:
My work is based on Dmitry Robsman's Cassini the 4.0 version of my VB port is based on the latest version i could find at that time on Dmitry's page he knows i made a VB port of his work as he send me an e-mail with CC to Lisa Feigenbaum to thank me for it .
I have never received feedback of annyone with complaints that something did not work , it just suited my needs just how it is ( so no need to work on it ) , i know there was in the past a CassineEX where the EX stood for Extended i downloaded the thing and at first wanted to use that one however it was pretty bloated in my opinion, i jut wanted a simple small and as fast as possible webserver, i did not needed log functions and all the other stuff that was implemented in the EX version .
But as you see i still support the VB version of Cassini it is not dead or left behind ,,, :-)
