Hi,
I'm currently on Chapter 16: managing Users with the WSAT. I'm unable to open the Web Site Administration Tools in my browser, so I open it manually by right-click the "ASP.NET Development Server - Port 64837" icon in the system tray and select "Open in web Browser". The "ASP.NET Web Site Administration Tool" webpage open up, but with an error message on it: "An error was encountered. Please return to the previous page and try again." There is no information about the error.

I'm running VS2012 Professional on Windows 7 SP1 64-bits.

Any idea what might be the cause?

Thanks and have a nice day.

Why can't you open WSAT in your browser?

Hi,
After some testing, I manage to open the WSAT in the browser and below is what I observed:
1) If my browser was running before I click the "Website->ASP.NET Configuration" in the VS, the WSAT page did not open... the browser become the active program, but nothing happen. If I open the WSAT page via the system tray icon, WSAT page open with the above error message show in the page.

2) If my browser was not running and I click the "Website->ASP.NET Configuration" in the VS, the browser run and after a while, show the WSAT page without error.

Not sure why, but at least I can now continue the "Try IT OUT" (hopefully).

Have a nice day.

Interesting. You may also want to consider trying a different browser. Not sure which you're using now.

Hi,
Only FireFox had this issue. I'm using FireFox 19.0.2.

Internet Explorer had no such problem... a new instance of the Internet Explorer will run and show the WSAT correctly.

Google Chrome also no problem... a new tab will open amd show the WSAT correctly.

Have a nice day.
