After opening the VS a few days ago, "Visual Studio.net has detected the specified web server running is not ASP.NET1.1. You will not be able to run the ASP.NET web application or service", it is true that Best can't help but know. After re-installed the VS, the situation is still search, and the search is searched on 9CBS. I found that the problem was originally set to "IP Address" in the IIS's website attribute into a specific IP. If it is changed (all unallocated ), It is said that this problem is not a version of the problem.
In the future, everyone will have the same problem as me, and there may be the following:
1, first determined if it is 1.1
2. Set "IP Address" into all unallocated
3, in the IE connection setting, put the local address without using the proxy server.
4, run the ASPNET_REGIIS -I
