You cannot open ASP.NET Web application project after deployment

You create an ASP.NET Web application project, and then you deploy the project on another computer. When you try to open the deployed project, you may receive the following error message:

To work around this problem, use any of the following methods. For more information about each of these methods, click the method to view the procedure.

• Manually copy the project files to the deployment computer
• Deploy the project by using the same virtual directory name
• Rename the Webinfo file and the project files

Manually copy the project files to the deployment computer

1. On the deployment computer, create a folder named Project1 in the C:\Inetpub\Wwwroot folder.
2. On the deployment computer, create a virtual directory named Project1, and then map this virtual directory to the C:\Inetpub\Wwwroot\Project1 folder.
3. Copy all the project files from the devserver computer to the C:\Inetpub\Wwwroot\Project1 folder that you created on the deployment computer.
   
   Note devserver is a placeholder for the name of the development (or source) server.

Deploy the project by using the same virtual directory name

When you deploy the project by using Microsoft Windows Installer, change the name of the virtual directory of the project to be the same as the name of the virtual directory of the original project (Project1). By default, the virtual directory name that the Setup wizard provides is the name of the Web Setup project (WebSetupProject1).

For more information, see step 5 of the "Run your Web Setup project on a remote (deployment) computer" section of this article.

Rename the Webinfo file and the project files

After you deploy the project by using a Web Setup project, rename the Webinfo file and the project files to map to the virtual directory of the project. To do this, follow these steps:

1. In Microsoft Windows Explorer, locate to the C:\Inetpub\wwwroot\WebSetupProject1 folder.
2. Rename the following file, depending on your project:
   • If you are using Microsoft Visual C# .NET or Microsoft Visual C# 2005, rename the Project1.csproj.webinfo file to WebSetupProject1.csproj.webinfo.
   • If you are using Microsoft Visual Basic .NET or Microsoft Visual Basic 2005, rename the Project1.vbproj.webinfo file to WebSetupProject1.vbproj.webinfo.
3. Rename the following file, depending on your project:
   • If you are using Visual C# .NET or Visual C# 2005, rename the Project1.csproj file to WebSetupProject1.csproj.
   • If you are using Visual Basic .NET or Visual Basic 2005, rename the Project1.vbproj file to WebSetupProject1.vbproj.
