Ms sql2005 was just installed yesterday. Due to the old version of vs2005, you must change the number of versions when installing sql2005. Program And components, including. net framework2.0, because sql2005 is a Chinese version, it must be installed.. Net framework2.0language package. It can be found that the setup.exe error occurs at the time of installation. There is no way to download one online. net frameworr2.0 Chinese package, finally skipped a sql2005 installation program, successfully installed.
Start to run vs2005, but when F5 or Ctrl + F5" ASP. NET development server failed to start listening on port **** ", And then jump out of the warning box" Error Unable to connect to visual stutio's localhost Web Server ", I found a lot of information online. The main solution is:
  • Does the fileWebdev.webserver.exeExist in c: \ windows \ Microsoft. NET \ framework \ v2.0.xxxxx?
  • Is Ie your default browser? Make sure in Internet Explorer, tools | Internet Options, Connections tab, LAN Settings, that you have 'Bypass proxy server for local addresses 'checked if you are using a proxy server.
  • If Windows Firewall is running check Windows Firewall settings. Turn on the option on the exceptions tab to "Receive notifications when firewall is running". It's possible firewall is blocking webdev.webserver.exe
  • What happens when you press Ctrl + F5 instead of F5 to run the site? CTRL + F5 is 'run without debugging'
  • What do you see in your browser when you type the address http: // localhost: 80?

    Then follow the prompts above to find a solution. But none of them are found.
    Later, it was found that the original. Net framework2.0 version was too low. reinstalling. Net framework2.0 could not solve the problem,You can only create a new solution. After adding the previous project, no problems will occur during running.However, this is so troublesome that no simple solution has been found.
