SYMPTOMS

When you try to create a Microsoft ASP.NET Web Application project or an ASP.NET Web Service project, you may receive the following error message:

Cannot create the offline cache in 'C:\Documents and Settings\UserName\VSWebCache\ServerName\ProjectName'. Unable to create a disk-based web at "C:\Documents and Settings\UserName\VSWebCache\ServerName\ProjectName" because its parent web would not be a disk-based web. Create the disk-based web elsewhere, outside of your web server's document hierarchy.
Note UserName is a placeholder for your user name, ServerName is a placeholder for the name of your Web server, and ProjectName is a placeholder for the name of your project.

Note The word "web" should be "Web" in this error message.

CAUSE

If the root folder of your hard disk drive (such as drive C) that contains the Microsoft Windows folder contains Microsoft FrontPage Server Extensions (FPSE) folders (such as _vti_pvt and _private), FPSE assumes that the whole hard disk drive is a server-based Web. Therefore, you cannot create any disk-based Webs in the hard disk drive with FPSE.
Back to the top

RESOLUTION

To resolve this problem, delete all FPSE folders (such as _vti_pvt and _private) from the root folder of your hard disk drive (such as drive C).

STATUS

This behavior is by design.

MORE INFORMATION

Steps to reproduce the behavior

  1. Verify that the root folder of your hard disk drive (such as drive C) that contains the Windows folder contains FPSE folders (such as _vti_pvt and _private).
  2. If the root folder of your hard disk drive does not contain FPSE folders, copy the _vpi_pvt folder and the _private folder from the C:\Intepub\wwwroot\ folder to the root folder of your hard disk drive.
  3. Try to create an ASP.NET Web Application project. To do this, follow these steps:
    1. Start Microsoft Visual Studio .NET.
    2. On the File menu, point to New, and then click Project.
    3. Under Project Types, click Visual Basic Projects or click Visual C# Projects.
    4. Under Templates, click ASP.NET Web Application.
    5. In the Location box, type http://ServerName/ProjectFPSE1.

      Notes
      • ServerName is a placeholder for the name of your Web server.
      • ProjectFPSE1 is a sample ASP.NET Web Application project.
    6. Click OK.

      You may notice the error message that is mentioned in the "Symptoms" section of this article.

In my case, I didn't have any of those _vt folders so I looked elsewhere for the cause, which turned out to be due to the fact that my C drive had run out of space. When I freed some space up (by compressing the HTML Help folder) everything worked fine. Thus, I suspect that your suggestion may have worked in some people's case because of the same reason.

If I have a decimal in the URL of my web service, it gives me an error [cannot create an offline cache in "C:\path\to\drive.1" invalid character in url "/C:/path/to/drive.1"]

Contd. 3/4/2009 11:59 PM entry this is the case when the project path and virtual path are not same. e.g. Path is C:\CodeBase\Module1.1\Server1.5 and Virtual path is http://localhost/MyApps/1.5/Server/... If the actual path and virtual path are in sync, there will be no issue.
