First, the error message "unable to configure the project is not debug" when debugging the ASP.NET application
symptom
When you debug an ASP.NET application in Visual Studio .NET, the following error message may appear:
Error While Trying to Run Project: Unable to Start Debugging on The Web Server. The project is not configured to be debugged
For ASP.NET projects, verify that you have a valid project file called 'Web.config' for the URL specified and 'debug' is set to 'true' in that file. For ATL Server projects, verify that the 'DEBUG' verb Is Associated with your isapi extension. WOULD you like to disable future attempts to debug asp.net Pages for this project?
the reason
This error occurs mainly because of the following reasons:
The ASP.NET application has no web.config file. The execution license property of the current project folder in the Internet Service Manager is set to not.
solution
To resolve this issue, use one of the following methods according to your specific environment:
If your project doesn't have a web.config file, add a web.config file to the directory containing the ASP.NET application. If you work in Visual Studio .NET, use the item in "Project Explorer" in the Project Explorer, click Add new item, and then click the web configuration file.
If your project already has a web.config file, and the debug property in the "Compilation" section of the web.config file is set to True, follow these steps to set the execution license property of the project folder:
1 Launch "Internet Service Manager" and click the item you want to try to debug. 2 Right-click the item and click Properties. 3 Click the Directory tab. 4 If there is no in the execution license list, click "Display Script" and then click Apply.

the reason
This error occurs because users trying to perform remote debugging users are not members of the Debugger User group on the Microsoft Internet Information Server (IIS) server. Solution To add the appropriate user to the Debugger User group, follow these steps in the web server: 1 From the Windows Start menu, point to the program, point to Administrative Tools, and then click Computer Management. 2 In the left pane, click to expand your computer management, system tools, and local users and group nodes. 3 Click the group and double-click the debugger user. 4 In the Debugger User Properties dialog box, click Add. 5 In the Select User or Group dialog box, select the appropriate user, and then click OK. 6 Click OK to exit the debugger User Properties dialog. 7 Turn off the Computer Management Explorer.

6. Unable to debug an ASP.NET web application
symptom
When you debug an ASP.NET application in Microsoft Visual Studio .NET, you may display the following Microsoft Development Environment Error message:
Error while trying to run project: Unable to start debugging on the web server.The server does not support debugging of ASP.NET or ATL Server applications.Run setup to install the Visual Studio .NET server components.If setup has been run, verify that a valid URL has been specified.You may also want to refer to the ASP.NET and ATL Server debugging topic in the online documentation.Would you like to disable future attempts to debug ASP.NET pages for this project?
the reason
This error may occur if the Microsoft .NET Framework settings or installation is not completed correctly. When this error occurs, an application map of the ASP.NET file extension (such as .aspx) is not properly configured in the Microsoft Internet Information Service (IIS).

Note: You must replace Windows Directory in this path with the correct directory of your system.
7 If the application map entries are not found, follow the steps in the "Solution" section.

Verify that you are a member of the Administrator group and the Debugger User group on your computer. Non-administrators do not have the correct permissions of debugging the ASP.NET assist process (ASPNET_WP.EXE).
sweat! ... I finally finished, I hope to have some effects on users and users debugging with vs.net, less detours!
Remove the IIS mapping after deleting and reinstalling IIS
Overview Installs the Microsoft .NET Framework Software Development Kit (SDK) or Visual Studio .NET, the Internet Information Services (IIS) mapping is created to create associations for ASP.NET's new file extensions and settings. These settings will be incorrect if you do not install IIS when running an SDK or Visual Studio installer or after running an SDK or a Visual Studio installer. Expected phenomenon when trying to view the ASP.NET page.
When you try to create a new ASP.NET web application in Visual Studio .NET 2003, you receive the following error message:
Visual Studio .Net Has Detected That The Specified Web Server IS Not Running ASP.NET VERSION 1.1.You Will Be Unable to Run ASP.NET Web Applications Or Services.
More information
To fix the IIS mapping for ASP.NET, follow these steps: Run the ASPNET_REGIS.EXE utility: Click Start, and then click Run. In the "Open" text box, type CMD, then press Enter. Type the following command at the command prompt, press ENTER: "% windir% / microsoft.net / framework / version /ASPNET_REGIIS.EXE" -i
In this path, the version represents the version number of the .NET Framework installed on the server. When you type this command, this placeholder must be replaced with an actual version number. Register ASPNET_ISAPI.dll: Click Start, and then click Run. In the "Open" text box, type the following command, then press ENTER: Regsvr32% WINDIR% / microsoft.net / framework / version /ASPNET_ISAPI.DLREGSVR32 will return registration results.
