Thanks for the tip.

I had the same problem yesterday. I was too fast deleting the v2.0.... folder. Now after i copied the webdev.webserver from my second machine all is working fine again.

Cheers, Frank.

Thanks for the tip about the missing exe.  

Hi i am also facing same problem "Unable to connect to Visual Studio's Localhost Web Server", i have that "WebDev.WebServer.exe" file in my "C:\WINNT\Microsoft.NET\Framework\v2.0.50727" folder.

I am not able to detect exact cause to this problem.

I am not able to debug any web application.

Event Ctrl+F5 is also giving same error...

So, i get two error messages as below :

1. "Unable to find version of the runtime to run this application"

2. "Unable to connect to Visual Studio's Localhost Web Server"

Please help me out...

WebDev.WebServer.exe already exist but i replaced it with the one working on other machine...................It worked!!!!!!

I had a problem with .net 2005. When i install it and run it, it worked fine. I also restart my computer then also it was fine. But on another day when i come and run my project the same error comes. Then i again set up .net 2005. then it worked fine. But the same thing i have to do again and again setup of .net every day.

So suggest me the answer of my problem

Hi Rahul

My OS is Windows XP SP2

I am Admin on my box

My pc is part of Domain(Stand alone)

IIS is installed in my system.I have created a new project and began to run ,when trying execute from the internet explorer (http://localhost/....)    an error occured stating that it is wrong to use authinication mode  Windows in the web.config file

so what could be wrong i do not understand

Thanks so much for posting this!

I deleted the .NET2.0 folder earlier today to test a setup program's installer of the .Net framework. And after it installed I couldn't build my websolution anymore. Turns out I deleted this file! Thanks for the solution!

I get the same error message when I try to use the website menu->ASP.NET Configuration in the Visual Web Developer 2005 express edition to load the Web Site Administration Tool. I also get this if I right click on the open window and click "View in Browser". In All instances I get a local host Icon on my task bar Labeled ASP.NET Development Server, and a path such as http://Localhost:1548/WebSite2, which is the path to my website created by Web developer. If you right click on the Icon you get a dialog box with the following options "Run in browser", "Stop", and "Show Details". If you Click option 1 or 3 you get the above Error message "Unable to connect to Visual Studio's Local Host web server" but for option 1 the Internet Browser loads with a list of the files in the project which you can run to see if they will run in the browser for debugging. Option 3 does esentially the same thing but gives details about the physical path, the virtual path, Port Number, and the root URL which is a link you click on to do the same as option 1. With all these options I get the same error message as above every time I click any of the above options. Also I can not get the Web Administration tool to load and run no matter what I do. I have checked and all of the files and directories mentioned above are present in the right folders. I Have IIS installed on my computer and have tried loading and running the web administration tool in Visual Web Developer with IIS enabled and disabled but it makes no differance. I can run and debug aspx files from my virtual IIS directory with out any problems. Can Any body tell me why I am getting this error message and how to get the Web administration tool to run?    

i work on file system not on iis ,it was working fine

suddenly it started throwing this alert message--"unable to connect to visualstudios's localhost web server"

Same thing here. Windows XP Pro SP2 / Administrator, standalone. I created a new website in VWD2005 Express Edition, localhost/appname. When I go to Website-ASP.NET configuration it starts the ASP.NET Development server and in a while it throws "unable to connect to visualstudios's localhost web server:. I reinstalled .NET 2.0 and VWD2005 EE and it seemed to work fine. After an hour or so, same problem! I also did the aspnet_regiis thing as mentioned above. Help....

Sometimes, not always(!), I can start Menu-Website-ASP.NET Configuration AFTER I did a Menu-Build-Rebuild Website. Other times it gives me the error "unable to connect......" It also seems to depend on the portnumber that the localhost web server is openening. Windows Firewall is off. Can I shut down this webserver and always use IIS instead?

It gets even stranger.... I had two instances of SQLEXPRESS on my machine and I disabled the second one (SQLEXPRESS with FULLTEXTSEARCH enabled). Now my VWD is working fine! I can acces the ASP.NET configuration and I can use Visual Studio's localhost web server. I let you know if there are more problems from now on.

dude, i did something similar to what u did..i uninstalled VS2005 first without uninstalling the patch for WebApps.and then coz i cant uninstall the patch..i just tried to get stuff done by installing VS2005...ignoring the patch alltogether!one look at ur blog and i knew where i screwed up!!thanks a million dude!!

hi,

i am getting two errors like-

1.ASP.Net development server failed to start listening on port 1290.only one usage of each socket address is normally permitted

2.unable to connect to visual studio's localhost web server

i have installed VS2005 and i was working comfortably fine with the application yeasterday but today its showing me the above errors.i have that "WebDev.WebServer.exe" file in my "C:\WINNT\Microsoft.NET\Framework\v2.0.50727" folder.

I don't seem to have the WebDev.WebServer.exe in my C:\Windows\Microsoft.NET\Framework\v2.0.50727 folder. I seem to remember reinstalling .NET framework a while ago, and just tried to use ASP.NET Configuration from the Website menu... am getting the same "Unable to connect to Visual Studio's Localhost Web Server" error. No sure what I need to install, uninstall. Is there some way I can extract this file without uninstalling and re-installing?

Thanks!

Hi,

   I've got the message ("unable to connect...")trying to run website in file system.

   When I tried "aspregiis -i" it said that "setup has detected some errors".

   When I checked  the setup log file, I found 4 "failure" messages:

   - Failure Cleaning up registry: CleanupRegistry failed with HRESULT 80070002: 'The system cannot find the file specified.  '

   - Failure Waiting for service to start: WaitForServiceState failed with HRESULT 8007041d: 'The service did not respond to the start or control request in a timely fashion.  '

   - Failure Starting service: w3svc: StartServiceByName failed with HRESULT 8007041d: 'The service did not respond to the start or control request in a timely fashion.  '

Hi, Rahul

When I open in VWD 2005 a localhost website ("http://localhost/mysite") and press F5, it runs good.

But when I open site in file system("C:/mysite) and press F5 or Ctrl/F5 it gives the message ("unable to connect...")

Michael

when I create new site in LOCAL IIS mode it works fine. when I create even very simple page in file system (C:/WebSites/simple.htm) it is unable to connect ...

I reloaded VWD 2005 Express Edition, made sure WebDev.WebServer exist, but nothing changed. I guess my ASP.NET is not installed properly.

I tried to correct it but failed.

Michael

Maybe I need to correct my .NET Framework, and then reinstall ASP.NET?

Michael

Everything was working fine. Then, i made some changes in date to do some experiments. first i forwarded the date by few months. Then, put it back to current. In the meanwhile, it started giving these errors:

- asp.net development server failed to start listening on port 1038 an attempt was made to access a socket in a way forbidden by its access permissions

- unable to connect to visual studio localhost web server

I have verified the existence of file WebDev.WebServer.EXE at this path: C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727

its there.

can anyone give me some idea?

rahulso's brilliant suggestion of checking the pID in netstat and killing the process in the Task Manager solved my problem. It was a process called 'SR_Service.exe' which is to do with my VPN client.

Thanks Rahul :)

Thanks

Hi every body I want to till you that I was have this problem and I try alot of solutions to solve it but without any benefits but I found that the reason of this problem is this file that called WebDev.WebServer

that is exist at the path

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727

that when I get it from my friend from his pc and replace the new with the exist file I found that the program become very nice

and run all the web appliction without any problem

so that I put the new file  in host server to download it and to solve your problems.

hi all,

this is  Dilip,i am facing a huge problem, i did everything but it is still there.

My problem is

At the time of Debug for Windows application it gives error as "the application failed to initialize properly (0xc000007b)" and

for Web application it gives error as "unable to connect to visual studio's localhost web server"

Due to this i can not work on either Web  or Windows application at all.

I read several solution but all just hit and try methods but it won't help me. All say they just solved their problem by some luck but no one got exact solution.

I reinstalled VS 2005 and Win -XP both doesn't help and also format my machine then install fresh copy of both.

Also Reset IIS and install framework 2.0 but it won't help me.Even i don't have any firewall installed but same problem persist.

I also copy WebDev.WebServer.exe from my friends machine to my machine but no luck.

Please give some genuine solution, not just hit and try solutions.

I can not work on any type of application.

If this problem persist that means Microsoft VS 2005 and XP has some serious bug inside.

Please .......Provide  me solution.

I suffered the same issue "Unable to connect to Visual Studio's Localhost Web Server", and I have resolved it now.

It was due to a FIREWALL program installed on my PC.

so please make sure to uninstall or close any such program if running.

Ok  another fix to try....

After you have verified that you have the WebDev.WebServer.EXE file and can double click it and it returns with help information.

Take a look at your hosts file in the folder...

C:\Windows\system32\drivers\etc

Open Hosts and ensure you have an entry such as the following...

127.0.0.1       localhost

For some reason mine was garbled and I hadn't even touched it.
