Came into work this morning and discovered that my local asp.net developmentn server has stopped working. Im getting the following page :
[Code]....
Im running visual studio of my personal PC withing my company's network.
I have a Web App (VS 2010 Beta 2, using VB) and it works flawlessly on the development system. When I publish it, everything works fine unless I use an update panel. If I use the update panel, and try to use something such as a dragpanel, I get the following error.

Using VS2010 Pro, I started up an web site and got the message "WebDev.WebServer20.exe has stopped working" - a very similar problem was reported at

I checked C:WINDOWSassembly and found that System 2.0.0.0 was missing (again!), reinstalled it but still got

I had the strangest bug yesterday while trying to debug in vs.net 2005....
I had an '05 web application. I clicked the "Run" button to start debugging, and the webpage popped up fine. I could run through the pages fine. Everything seemed fine....UNTIL!
Until I tried to start inserting breakpoints into my code. The application ignored them. In addition, I noticed my little green visual studio "Start Debugging" arrow (which is normally greyed out while in debug mode) was green. It was as if visual studio completely detached itself from my website I was trying to debug.
After playing around with it for a while, I realized I also had a vs.net 2008 solution open as well. My '08 solution wasn't in debug mode or anything, it was just sitting there open. I just happened to close it, not thinking anything of it, and presto! My 2005 debugger started working again!
So basically, I can't debug an '05 solution (or at least a web solution, as that's all I tried) while I also have an '08 solution open.
i have installed latest vs 2010 ultimate on windows 7
it works fine but as i want to close a website it sayas vs has stopped working restart/debug
what should i do?
I recently ran into some strange problems. Changes to files that are not code-behind (and not gets compiled to a DLL) should not require you to recompile the whole website, and this has never been I problem for me. These should actually get compiled dynamically when you first access the resource, e.g. the first time when browsing an updated aspx-page in the browser.
But yesterday, during development of a website, I noticed that even the smallest changes in html, javascript or anything in the .aspx-files doesn't get reflected when I save and reload the page in my browser. Rebuilding doesn't help either, actually I'll have to do a "Rebuild All" (in Visual Studio 2008) in order to see the changes. This applies to all aspx-files in my project.
I tried with minor changes on files in another web application project on the same server, and there it works as it should. Something must has happened to this particular application, but I cannot figure out what. Do you have any ideas on how to solve this?

I have a zillion warning messages when I view my webform "Validation (): Element 'menu' is not supported" and every "<asp:WhatEver" tag has a green squiggly line under it.
It looks like this:

I am using IE8. I installed IE development tool bar when i used IE7. Right now Developemnt tool bar is not working in IE8 browser.

I am able to select the tool bar. But it does not dispaly anything to debug...
I'm a .NET specialist working with a PHP/Flash programmer to deliver an app via IIS. After jumping through 17 hoops of fire and defeating a gargoyle in a gruesome battle to the death, I managed to get my IIS 7.5 server to cooperate with PHP, and now if you browse to my public web site, you can see the Flash objects happily doing their behind-the-scenes stuff with PHP, whatever that may be.
But... when I'm debugging my app using the VS Development Server, that still apparently doesn't know how to cope with PHP: I'm getting the same HTTP 405 (Method Not Allowed) errors that I was getting on IIS before aforementioned gargoyle breathed its last ("The HTTP verb POST used to access path '/php/blah.php' is not allowed.").
So, what do you have to do to get the VS Dev Server to play nice with PHP?
When debugging my website project I usually go to start options in the web project's properties and select 'Don't open a page' and 'Use custom server' with a url that's in my host file pointing to my local IIS.
Even when I do this though visual studio still spawns it's own Development Server instance every time I hit f5.
Also for web application projects that have shared ascx files for instance Visual Studio will also launch an instance of Development Server each time I debug the solutions for each for these projects. This results in a million instances of Development Server running on my machine at any given moment.
Is there any way to disable development server for a given project completely? Without pointing it to a localhost sub application?
I'm getting "Cannot connect to ASP.NET development server" almost every time I stop the ASP.NET server before restarting the project in debug mode. It can take between 15 seconds and 2 minutes to get the error message, and Visual Studio is frozen.
Sometimes I get three in a row, and I have to wait 2 minutes each time, or go into Task Manager and kill to process. Then I have to start Visual Studio 2010 again, which is at least three times slower than Visual Studio 2008 to open.
It's *extremely* annoying. I know I don't have to close the server if the code has changed, but sometimes I simply want to restart my website in debug mode (there is a cache on most web service calls, so this clears the cache). A workaround is to add "foo" code to a class and restart the project.
I'm running Visual Studio 2010 Professional on Windows Server 2008. I'm running the Visual Studio Power Tools too, with the latest update.
Under IIS I would have to do a special configuration to support PHP. I have also found a number of references related to previous versions of VS which state that the development server would not, hence my question. Will the development server run the following PHP script server side in the header? Are there special configuration requirements?
<head id="Head1" runat="server">
<script type="text/javascript" src="http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php"></script>
A number of developers trying to create Silverlight apps intergrating Facebook have ran into the same wall with the MS Facebook SDK, and are struggling to determine the cause. I am assuming the script file contains the integration functions.
i want to know how do i deploy ASP.NET web applications on client machines which runs with the visual studio development server rather than configure it in the IIS on the client machine? I know its possible and telerik also uses this approach.
View 1 RepliesI'm getting this problem with one of my web projects. I've looked at [URL] and other suggestions around the place, none of which apply here. The odd thing is, it's occurring with *one* of my new web site projects, but not another one. Odd again is that they're both 100% fresh sites, created with the "New Web Site" option in the File menu, within a day of each other, and nothing has been done to them, apart from a bit of "hello world" html. WebSite1 was created first, and Cassini worked when I first created it the other day. A day later, I created WebSite2 and Cassini worked (and still works) with that one.
However, when I open WebSite1, I get the above error code - again, it was working fine the other day, and WebSite2 works fine. I've compared their .sln file - so differences apart from the VWDPort number used, and of course the path to the site and various GUIDs. Everything else is identical. Same with comparing web.config files. No differences there at all. So I'm stumped - why would Cassini start up fine with WebSite2 (and subsequent sites I create) but suddenly stop working for the WebSite1 project, when it was working ok a couple of days ago?
I'm attempting to run/debug an ASP.NET MVC project under .NET 4.0 using VS2010's Dev Web Server. The server appears to spawn successfully and an instance of IE Explorer opens. However, the browser never seems to find the page. The browser just "spins" showing only a white page...no error message.VS is configured to randomly select a port, although I get the same results when configuring numerous static ports.The ASP.NET project is the start-up project.
View 2 Repliesng an application that listens on port 25. My application will work as a SMTP server receiving emails. I am aware that I can just enable IIS SMTP feature, but for my current project, I needed to do in this way.If I can send emails to visual studio development server which has a private IP, my debugging will be much easier. Is there a way to send emails to VS development server?
View 1 RepliesWhen viewing an asp.net page in visual studio 2008, the asp.net development server icon shows up in the system tray. It can be stopped by right clicking on it and select "stop". In Visual Studio 2010, I do not see the icon any more. where the asp.net development server is? How to stop it?
View 3 RepliesI have a test website with VS 2008 that just uses code behind files, such as Foo.aspx.cs. Thus, the web server compiles them on the fly. The problem I'm running into is I can't use any C# 3.0 features. If I do:
[code]....
Then VS will work fine (everything gets highlighted and Intellisensed), but when I run the site it just throws up compiler errors..
Is there a way to fix this, or do you have to compile a DLL to target the 3.0 runtime? If so that's insanely lame.
Not too long ago I was given a new PC with windows 7 Professional on it. Before, I had vs 2008 running on win xp which worked OK. I started getting error msg (Unable to connect to ASP.NET development server) after I installed vs 2008 (version 9.0.30729.1 sp1 vs team system dev. edition) and ran one of my projects and even a simple test project. The first msg shows the syntax of webdev.webserver with an example in the bottom. I can get this error by running the project or by showing any page in the browser. I noticed that file WebDev.WebServer.EXE does not appear in the folder C:WindowsMicrosoft.NETFrameworkv3.5. If that's the only reason why I am having this problem than how can I fix it. I was told that .net framework 3.5 works on top of .net framework 2.0?! I just want to sort out this .net framework mess on my new machine. I am willing to uninstall all .net framework and start fresh. Another thing that I am willing to try is to get from a coworker the WebDev.WebServer.EXE (from the .net framework 3.5 folder) and see if it works.
View 2 RepliesI noticed a layout issue on the web app I'm working on, and in trying to correct it via the stylesheet I realized that the development server is not recognizing any changes I make to the .css file. As confirmation, I saved a blank stylesheet (which should have removed all styling), cleared my browser cache and rebooted my development machine and the original styling remained. It seems some version of the stylesheet is "stuck." The stylesheet is referenced in my master page, and the path specified is correct.
View 2 RepliesI'm using the Visual Studio Development Server, with a specific port. Is there a way to add a virtual directory to it?
EDIT:
I'd like to be able to add one or more virtual directories to arbitrary physical directories. For instance: [URL] would map to C:, [URL] etc.
Debugging using the ASP.NET Development server is extremely slow to initialize. The behavior I'm getting is that if I launch the DevServer from VS2008, the first attempt to load a page takes minutes. After that, it's fine. Before the first page load, the DevServer UI responds to input normally (I can bring it up from the status area, use its context menu, and move the window around) until the first page load comes in. Then it shows the busy cursor (spinning blue ring) for 2-6 minutes before finally completing. There is no significant processor or I/O activity during this. After that, it runs normal speed, quite fast.
