I reinstalled VS. and IIS Web server and after that I don't have that error message.
But still there's converting version problem exsit.
There's no .aspx files but only showing files are .cs
This one doesn't let me compile since I don't have no 'start up' project to compile it.
When I was using VB
.net and had another incident like this before.
What I did was, first I made project name first then copied all the files into that directory except, global.asax, assembleinfo then it is bring up aspx pags.
but still program is not properly.
