Visual Studio | ASP.NET configuration error

Question

I have a problem that I struggled with for a week. Now i give up! I really can't figure out how to solve it. Each time I open the ASP.NET configuration in VS10, the first one appears with this error: ** An error was detected. Return to the previous page and try again. **

If I then click: How to use this tool

so it happens: ** Tool runtime

As a security measure, the Website Administration Tool expires after a period of inactivity. Changes to the machine.config or web.config file may also cause the tool to restart. Restart the tool to continue setting up your website. **

Who can answer me what is happening here?

Answer 1

"Special characters in the path may be a problem, according to reports." as said above by Dave Svirsky

THIS worked great for me! I had a special character (" # ") in my path to the folder that I deleted, and deleted spaces for good measure! I get an error message . The tool is disabled among other errors when accessing the WSAT (website administration tool) from the ASP.NET configuration menu item.

Answer 2

I saw a message somewhere else saying that the problems were resolved when the default browser was changed to Internet Explorer. I am using Firefox and have the same problem. When I changed the default browser in IE, the configuration page came up without problems. But it will not work twice in a row without entering and each time setting the default browser in IE. When I return to Access to the Program and By default, "Use current browser" is selected. I have to reselect IE and then it will work once.

Judging by the Connect website, this error is reported and is not entirely clear:

Special characters in the path may be a problem, depending on the messages.

Answer 4

This is what worked for me.

I am using Visual Studio 2010 trying to create a membership role. I tried to use ASP.NET configuration in Visual Studio.

Install the "Default Browser" in Internet Explore.

For this:

• Right-click on one of the .aspx pages that you have in the Solution Explorer.

• Select "Browse with ..."

• Select Internet Explore and click "Set as Default."

• Close the window.

• Go back and click on ASP.NET Configuration

• This will automatically open Internet Explorer.

Solution: D

I assume what I did wrong, used Firefox as the default browser with Visual Studio. I guess Visual Studio works well with Internet Explorer, since Momma and Daddy combined them (and also how cute)

Answer 5

The problem may be with the application pool with spaces. After googling, I managed to work around the problem by manually adding the application path to the URL, i.e.

http://localhost:{your_port_here}/asp.netwebadminfiles/default.aspx?**applicationPhysicalPath={path_to_your_application}&applicationUrl=/** 

Answer 6

As a firefox user, I closed firefox and then executed the option "ASP.NET Setup" in VS2010. It automatically opens firefox (default browser), and now I see the contents of the WAT page.
