There is a prompt when you build a web application when you build a web application, in addition to the most stupid method - reloading VS.NET, the causes and solutions of the problem are as follows:
1. Your web server uses fixed IP: Determines your "Internet Information Service" to use the "default Web site" and its IP address in its properties "(all unallocated)", not your own IP address. Then retry in returning to vs.net, perhaps can be resolved.
2. The above method cannot solve the problem, consider the solution in MSDN, as follows:
Visual Studio .NET cannot be determined whether it is an ASP.NET version 1.1 on the web server computer. This error may occur in several different situations. Please check if you belong to the following:
Make sure the .NET Framework version 1.1 is installed on a web server computer. For more information, see Visual Studio .NET software requirements. If the ASP.NET is already installed on a web server computer, it is still encountered that this error may be a configuration problem. In order to correct problems installation or configuration, ASP.NET utilities named ASPNET_REGIIS can be used. This command line utility can be found in the path similar to the following: C: /Windows / Microsoft.Net/framework/v1.1.nnnn/
Where nnnn represents the four internal version numbers. Find in the highest version number. Run the utility using the / I switch:
ASPNET_REGIIS / I
Tip You can open the command window directly from the correct directory of the command. From the "Start" menu of Windows, point to Programs, Visual Studio .NET 2003, "Visual Studio .Net Tools, then select" Visual Studio .NET Command Tips ". Type ASPNET_REGIS / I after the window is opened.
