ASP.NET and Source Code Appearing - asp.net

I have an older ASP.NET web-application using framework 2.0 based on Dot Net Nuke. The web-application used to compile and run but recently it compiles fine but instead of the application running in the browser, source code appears. What could be causing this type of behavior? Thank you.

Sounds to me like IIS is treating your .aspx files as static content.
Open IIS admin and make sure the .aspx extensions are mapped to PageHandlerFactory. Make sure the pages exist in an application (and not just a virtual directory). Easiest thing to do is open up IIS in a known good environment and compare the setup.
Also, make sure you have run aspnet_regiis with the appropriate .NET version.

Windows Server 2003 IIS Renders ASP.NET 4.0 pages as blank

I have a web project which works fine on my local development machine.
I copied the project to our UAT server, setup a virtual directory pointing to the project and configured it to run on .NET Framework 4.0. I even added the Default.aspx page to the Documents tab. I configured Directory Security to use Windows Authentication.
When i try to access any web page within this application, IIS responds with a blank page. I looked through the event logs and don't see any errors anywhere.
Can someone please help me understand what's going on and how to remedy this?
Thanks in advance!
If you're just seeing a white page with no errors in the event log, it sounds like it could be a problem with the application rather than the hosting environment.
However, there are a few things you could try to doing to troubleshoot this.
Check folder permissions. Try allowing "Everyone" access on your webroot folder and see if that makes any difference.
Confirm that the IIS path is set up correctly but putting a text file in your webroot folder, and then browsing to it and verifying that it's contents are displayed.
Create a basic test.aspx page without any script, just a "Hello World" bit of text, and try browsing to it. Confirm that it displays the correct content.
Edit web.config and turn off custom errors
Try re-registering the ASP.NET extensions with IIS using aspnet_iis (details here)
Hopefully, one of these tests will be able to give you some kind of detailed error message or more insight into the cause of the problem.
For IIS 6.0 on Windows Server 2003, after the install of .NET Framework 4.0, the process of creating Web Sites or Virtual Directories that run under .NET Framework 4.0 is as follows:
Create a new application pool.
Applications running under different
frameworks can't be hosted in the
same application pool, i.e. create
an application pool perf framework.
Next, if you are creating a local
intranet site or virtual directory,
ensure that you don't have "dots" in
the application name. Browsers
confuse the dots to be external web
sites, forcing them to run under
internet zone as appose to the
intranet zone.
Once you create your web site or
virtual directory, make sure that it
runs under an application pool
dedicated for .NET 4.0 applications.
Ensure that when creating your
website or virtual directory, you
click on the ASP.NET tab and select
version 4.0 from the drop down.
Then you may configure as per
normal, with any other additional
settings you may require.
Hope this helps someone experiencing similar issues. Took a while to figure out.

Compiled ASP.NET App Doesn't Parse Classic ASP

If I shove our intranet app live and let it be compiled on the fly without compiling it beforehand it works fine. If I publish the site by compiling it first using VS's built in publishing feature then every page works fine except for the classic ASP pages.
Anyone know why this would happen? We have classic ASP because there's thousands of pages, many migrated from old systems but we simply don't have time to convert them all (just before anyone starts saying "just convert them!").
Cheers!
When you publish the app, VS only copies the files needed by the app and/or referred in the project file.
Maybe the ASP classic pages depends on a file that it's not included on the published site.
To test it, publish the site, and then compare the files in the server with your local copy to check for missing files. (You can use a tool like Beyond Compare)
ASP classic isn't enabled by default on newer versions of IIS.
Here's how to enable it on IIS7.

Subversion and using IIS for ASP.NET development

I'm a total newbie to SVN and haven't been able to find an answer for the following situation.
I have an ASP .NET 2.0 web app that I am developing. I am using my local IIS as the development web server (i.e. not the Visual Studio web development server). My development environment is VS2005, Vista, IIS7, TortoiseSVN / AnkhSVN. VisualSVN is installed on the server.
My .sln files and class libraries, etc. are located in the **C:\Localsource\Projects\ProjectName** folder, and my .aspx files are in my **C:\inetpub\wwwroot\ProjectName** folder.
I can set up the repository for **C:\Localsource\Projects\ProjectName** fine, but can't think of a way to set it up for the IIS folder as well in the same repository.
What's the best way for dealing with this development environment in SVN?
Many thanks,
Ant
In a solution in Visual Studio you can have a class library project which is usually in a directory underneath the .sln file.
In this case he also has a web project within the solution but NOT underneath the .sln file in the file directory structure.
He will be attaching to this project via HTTP not via local file path.
IIS will manage this as http://localhost/webapp and by default will place it in c:\inetpub\wwwroot\webapp. The files in webapp folder will not be in the repo as they arent in the hierachy of the solution and the class library. This is his question how to sort it out.
My answer is to move http://localhost/webapp to point to a folder that is underneath the .sln file and adjacent to the class library directory then it can all go in the repo.
Seperating the class library and the the webapp is best practice to aide code re-use and decoupling the logic from the web site.
Can you not just point IIS to C:\Localsource\Projects\ProjectName and set the permissions?
Hmmm - Good point. It was set up like this when I got here, and Visual Studio always creates websites in the wwwroot folder, so I assumed wwwroot was just where they had to go.
Maybe I'll have to think about doing a little rearranging...
Thanks!
The IIS folder is not the output of the code base it is part of the application. It's not CGI output or anything but actually the scripts to run the app!
This is the .aspx pages that will have user controls and HTML to actually run the application. Its part of the applciation but split away from VS Studio solution.
The easiest way is to have a solution and then C:\Localsource\Projects\ProjectName\WEBSITE.
Point IIS at that folder as well.
OK, I may be being stupid here but.. Why do you need to add the IIS folder (i.e. the output of the code base) to your repository?
Update
I think I should clarify this a bit more.. What I mean to say is I am not sure why the ASPX is seperate from the project anyway? What is wrong with an Web Project and n Class Library Projects in a Solution, added to your repository.. You then publish on each new release..
If it is simply a case of "it might be easier to roll back the published output" then so be it, I was just curious as I have not seen many people actually work that way.
Deployment of solutions in this structure would be a lot easier as well..
I think you might want to separate this into two problems, following this recommendation from Dillorscroft.
First, with regard to the material on your development server that is published to the production site, I think you need version control for that. First so you can roll back any page, and you can also decide when you have a stable level of the development site that you want to extract to production. (I would get that from the source control system into a site image and then synchronize that image with the production site.)
So, for the first part, we are talking about versioning the web pages and all of the custom server-side material that supports the web site.
Secondly, With regard to the development of components that are used on the site, they need their own development projects, since it is the result that goes to the development site, not all of the source, libraries, etc. that the component is built with. So these will have their own project development tree (think of it as if you were building a library that is to be used by other development projects, although in this case the other projects are web pages). So the only thing that should show up in IIS is the "deployed" component to the development site.
There seem to be three critical questions for you:
How development of tests that need to go against the web site is handled and where that is version controlled (assuming they do not belong on the web site itself)
How easily you can arrange to make sure that all content on the development web site is kept under version control and checked-in and -out appropriately. (This has to do with the tools you use to edit web pages and other server-side gunk other than components developed off to the side.)
Easily taking developed components from the projects that produce them to the development site and have them be checked-in there.
My solution to (2) and to version control of the development web site is to use Visual Source Safe integration with IIS and FrontPage extensions that places the site under version control. Components produced from other development projects are mapped to the server project by VSS sharing.
For SVN, I speculate that (1) you want to see if there is an SVN adapter that IIS will recognize as an external source-control system and, either way, (2) have a discipline that takes delivery of components from their construction projects into the overall web site project.
Rob,
Why do you consider an .aspx file an output of the code base?
It is part of the code base. It's not an output after compilation for instance.
Just wondered?

How can I use the "Publish" function in Visual Studio 2008 without erasing the contents of the target folder?

When I use Build->Publish Web Site in Visual Studio 2008, most of the time it compiles the site, and then simply asks me "All files in the target folder will be deleted. Continue?" (or something to that effect). On occasion, however, when publishing a project in Visual Studio, I would get a dialog box that would give me the choice of replacing the folder's contents completely, or simply replacing changed files with newer version.
I much prefer to publish without completely obliterating the folder, because the deployed application creates user files and cache files as it's been used that I don't want to take extra steps to preserve. However, I'm not sure why Visual Studio doesn't always give me this option. Is this a setting somewhere I can change? Is it tied to the version of .NET I'm using?
Any insight is appreciated!
Edit - Followup on 2009-01-20
I still haven't figured this out, but here's some more information.
Here's what the publish function looks like for one ASP.NET project on my Win XP desktop:
And here's what it looks like for a different project on my Vista laptop:
Notice the radio buttons in the second screenshot that allow me to choose to either delete the contents of the folder prior to publishing, or merely to overwrite matching files. I'd like to have these options for every project.
Both computers are running Visual Studio 2008 Professional (version 9.0.30729.1 SP, according to Help->About). The exact same version. And I doubt the OS difference is causing this functionality change. It's got to be a setting somewhere, right? Does anyone know?
John is right, the only difference is one of your projects is a Web Site Project and the other is a Web Application project. You will not see the "convert to web application" option unless you are in a Web Application project. I know... it is very misleading. The reason behind this stems from the the way you convert to a web application project. If you plan on converting it(which can be a real pain in arse, depending on how it is set up) then you need to be aware of a few differences:
In a Web Application project everything is pre-compiled all the codebehind pages will be compiled into a .dll ---- In a Web Site Project nothing in the project is pre-compiled, the compiler will compile everything to ensure it is valid but none of the compiled pages are uploaded. When a user first attempts to access the site each page is compiled into its own dll. This means in a Web Site Project you are able to upload a single codebehind file.
Namespaces - In a Web Application project namespaces are created by default in a Web Site Project they are not. So you may have to spend some time adding them if you plan on converting them.
Project files - you will notice that A Website Project does not have a "cproj" file a Web Application project does.
I have converted a few of these project I find they go fairly smooth as long as there is not a lot of code in the "app_code" folder. You can give it a try and see how easy it is, if it looks like it is going to be a pain, I would suggest FileZilla just FTP it and save yourself some headache.
Good Luck
That dialog is different for Web site projects and Web application projects. In my MVC projects (Web application projects), I see the additional options. In my regular ol' web site projects, I see the first dialog posted.
Not sure if this option will be suitable for you but you could use the copy website function from the solution explorer. Click on the "Copy Website" icon at the top of the solution explorer.
I think the real answer to your question is that you should put your user files and cache files somewhere else.
When publishing a web site Visual Studio is designed to make sure that the target folder contains your web site files, and absolutely nothing else.
Apparently this feature is coming in VS2010 - that's what Vishal Joshi announced at TechEd EMEA in session "PDC307: Microsoft Visual Studio 10: Web Development Futures"
The site has been updated from the site in the updated layer.

Could not load type 'XXX.Global'

Migrating a project from ASP.NET 1.1 to ASP.NET 2.0 and I keep hitting this error.
I don't actually need Global because I am not adding anything to it, but after I remove it I get more errors.
The reason I encounter this issue is because I change the build configuration. When I set a web project to x86, it changes the output path to bin\x86\Debug. However, the output path should be bin and the web server won't find the binaries because of this.
The solution thus is to change the output path of the website back to bin after you change the build configuration.
There are a few things you can try with this, seems to happen alot and the solution varies for everyone it seems.
If you are still using the IIS virtual directory make sure its pointed to the correct directory and also check the ASP.NET version it is set to, make sure it is set to ASP.NET 2.0.
Clear out your bin/debug/obj all of them. Do a Clean solution and then a Build Solution.
Check your project file in a text editor and make sure where its looking for the global file is correct, sometimes it doesnt change the directory.
Remove the global from the solution and add it back after saving and closing. make sure all the script tags in the ASPX file point to the correct one after.
You can try running the Convert to Web Application tool, that redoes all of the code and project files.
IIS Express is using the wrong root directory (see answer in VS 2012 launching app based on wrong path)
Make sure you close VS after you try them.
Those are some things I know to try. Hope one of them works for you.
I've found that it happens when the Global.asax.(vb|cs) wasn't converted to a partial class properly.
Quickest solution is to surround the class name 'Global' with [square brackets] like so (in VB.Net):
Public Class [Global]
Inherits System.Web.HttpApplication
...
Deleting the existing global.asax file and adding a new one, clears out this error. This has worked for me many times.
If your using visual studio 2010 this error can occur when you change the configuration deployment type. The 3 types are x86, x64 and Mixed mode.
Changing to mixed mode setting for all projects in solution should resolve the issue. Don't forget to delete the bin, Lib files and change the tempdirectory output if your an ASP.NET website.
This just happened to me and after trying everything else, I just happened to notice on the error message that the app pool was set to .Net 1.1. I upgraded the app to 2.0, converted to web application, but never changed the app pool:
Version Information: Microsoft .NET Framework Version:1.1.4322.2490; ASP.NET Version:1.1.4322.2494
This one drove me completely insane and I couldn't find anything helpful to solve it. This is probably not the reason most people have this issue but I just hope that someone else will benefit from this answer.
What caused my problem was a <clear /> statement in the <assemblies> config section. I had added this because in production it had been required because there were multiple unrelated applications on the same hosting plan and I didn't want any of them to be affected by others. The more correct solution would have been to have just used web config transforms on publish.
Hope this helps someone else!
Changing the address's port number (localhost:) worked for me :)
I fixed this error by simply switching from Debug to Release, launch program (It worked on release), then switch back to Debug.
I tried just about everything else, including restarting Visual Studio and nothing worked.
I had this same problem installing my app to a server. It ended up being the installer project, it wasn't installing all the files needed to run the web app. I tried to figure out where it was broken but in the end I had to revert the project to the previous version to fix it. Hope this helps someone...
In my case, a AfterBuild target in the project to compile the web application was the reason for this error.
See here for more info
Removing Language="c#" in global.asax file resolved the issue for me.
In my case, I was duplicating an online site locally and getting this error locally in Utildev Cassini for asp.net 2.0. It turned out that I copied only global.asax locally and didn't copy the App_code conterpart of it. Copying it fixed the problem.
When you try to access the Microsoft Dynamics NAV Web client, you get the following error.
Could not load type 'System.ServiceModel.Activation.HttpModule' from assembly 'System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089
This error can occur when there are multiple versions of the .NET Framework on the computer that is running IIS, and IIS was installed after .NET Framework 4.0 or before the Service Model in Windows Communication Foundation was registered.
For Windows 7 and Windows Server 2008, use the ASP.NET IIS Registration Tool (aspnet_regiis.exe,) to register the correct version of ASP.NET. For more information about the aspnet_regiis.exe, see ASP.NET IIS Registration Tool at Microsoft web site.

Ensure compiled dll of your project placed in proper bin folder.
In my case, when i have changed the compiled directory of our subproject to bin folder of our main project, it worked.
Had this error in my case I was renaming the application. I changed the name of the Project and the name of the class but neglected to change the "Assembly Name" or "Root namespace" in the "My Project" or project properties.
Deletin obj, bin folders and rebuilding fixed my issue
I had this problem.
I solved it with this solution, by giving CREATOR OWNER full rights to the Windows Temp folder. For some reason, that user had no rights at all assigned. Maybe because some time ago I ran Combofix on my computer.
