Cannot access files from Azure Web App - c#

We have created an Azure web app. We want to use this app to enable our site visitors to download appxbundle of our UWP app. We are able to put the files on the folder and can see them through FTP. However as soon we try to access the files by just typing the resource URI in the browser it throws an error at us stating:
The resource you are looking for has been removed, had its name
changed, or is temporarily unavailable.
I tried putting the file in the root directory as well but the error remained the same. From this blog we know that it can be done but somehow we are not able to make it work. Any idea how can we make it happen?

Turns out that MIME types need to be explicitly copied into the web.config file. You can check for these in the Visual studio as well but if you want to configure it manually then make sure you add the following lines to your web.config
<system.webServer>
<staticContent>
<mimeMap fileExtension=".appinstaller" mimeType="application/xml" />
<mimeMap fileExtension=".appxbundle" mimeType="application/vns.ms-appx" />
<mimeMap fileExtension=".appx" mimeType="application/vns.ms-appx" />
</staticContent>
</system.webServer>
Adding this snippet got us through the access error mentioned above.

Yeah, that's a regular case of MIME types.
Add the following to the section of your Web.config:
<staticContent>
<mimeMap fileExtension=".appxbundle" mimeType="application/xml" />
</staticContent>
Alternatively, try it with mimeType="application/octet-stream", depending on whether you want it to be downloaded or "inlined" (which for .appxbundle, i don't know what it means, maybe kick off install/open Windows Store?)

IIS 10 can't read web.config (try to deploy Blazor), Error 500.19 with 0x8007000d [duplicate]

I am replicating web application deployment and found several issues related to HTTP Error 500.19. My machine is running Windows 7 while the working development is using Windows 8. We're developing our Web Application using Visual Studio 2010.
First, I got error code 0x80070021, similar as posted here.
I update my web.config according to the accepted answer and then I got following error code (which is similar as posted here).
HTTP Error 500.19 - Internal Server Error
Error Code 0x8007000d
Config Source -1: 0:
I have read the symptoms definition in Microsoft support page and cause of the error is:
This problem occurs because the ApplicationHost.config file or the Web.config file contains a malformed XML element.
and the solution is
Delete the malformed XML element from the ApplicationHost.config file or from the Web.config file.
However, the web.config that I used is working perfectly in the original development environment.
Here is what I have checked and tried so far:
Install ASP.NET by calling aspnet_regiis -i
Set my application to use different application pool (ASP.NET v4.0, .NET v4, etc)
ApplicationHost.config file is still using default from Windows 7.
This is part of my Web.Config
<system.webServer>
<section name="handlers" overrideModeDefault="Allow" />
<section name="modules" allowDefinition="MachineToApplication" overrideModeDefault="Allow" />
<validation validateIntegratedModeConfiguration="false" />

</system.webServer>
I have read similar/duplicates/closed posts (around 13) posts in stackoverflow, tried all except the answer related to Ajax (is it related) and still have no clue on what the error is.
Does anyone one how to fix this error? (And if possible, a comprehensive lists of things need to be checked so we can reduce similar posts like this.) I am ready to provide more details.
Error 0x8007000d means URL rewriting module (referenced in web.config) is missing or proper version is not installed.
Just install URL rewriting module via web platform installer.
I recommend to check all dependencies from web.config and install them.
When trying to set up a .NET Core 1.0 website I got this error, and tried everything else I could find with no luck, including checking the web.config file, IIS_IUSRS permissions, IIS URL rewrite module, etc. In the end, I installed DotNetCore.1.0.0-WindowsHosting.exe from this page: https://www.microsoft.com/net/download and it started working right away.
Specific link to download: https://go.microsoft.com/fwlink/?LinkId=817246
Yes, for .net core apps, install dotnet hosting. This worked for me.
And here it is for .net6
And now if you need .net7
Install URL rewriting:
UPDATE - this is now available here (and works with IIS 7-10):
https://www.iis.net/downloads/microsoft/url-rewrite
Ensure you have the following set to 'Allowed' for your IIS server:
In my case, because I had reinstalled iis, I needed to register iis with dot net 4 using this command:
C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -i
In my case (.Net Core Web API) for this issue HTTP Error 500.19 – Internal Server Error 0x8007000d
First download dotnet-hosting-3.0.0-preview5-19227-01-win (.Net Core 3) or dotnetcore 2 hasting windows
https://download.visualstudio.microsoft.com/download/pr/5bed16f2-fd1a-4027-bee3-3d6a1b5844cc/dd22ca2820fadb57fd5378e1763d27cd/dotnet-hosting-3.1.4-win.exe
Any .net core 3.1 application either angular or mvc application would need this.
Second install it as Administrator
Open cmd as administrator, type iisreset, press enter
So refresh your localhost app

A repair of the DotNetCore hosting bundle did the trick for me. :/
Installing ASP.NET Core Runtime Hosting Bundle solved the issue for me. Source: 500.19 Internal Server Error (0x8007000d)
Kind of late to the party here, but I have just been struggling with the exact same issue (symptoms) and cursing the lack of error detail reporting.
It worked fine on IIS 8+ machines but Win 7 got these INSTANT HTTP 500.19 errors.
For me it was as silly as having an unsupported configuration element in the config file:
<applicationInitialization doAppInitAfterRestart="true">
<add initializationPage="/" />
</applicationInitialization>
So while running old web.config files worked fine, I just diffed them and started chopping away at new blocks until I got the page to start loading. Had I seen this as an answer I would have gone this route immediately as I knew none of the popular solutions were relevant. So there you go :)
I turn on .Net Framework 3.5 and 4.5 Advance Service in Control Panel->Programs and Features->Turn Windows features on or off.it work for me.
Problem solved. Here are the steps that I tried:
Enable the 32-bit application in IIS -> Application pool -> Advanced settings
Copy System.EnterpriseServices.dll and System.EnterpriseServices.Wrapper.dll from C:\Windows\Microsoft.NET\Framework\v2.0.50727 to the application bin folder
Do comments/uncomments to sections on the web.config and found that problem related to the referenced DLL.
The config that I commented the previous one that I added:
<section name="handlers" overrideModeDefault="Allow" />
<section name="modules" allowDefinition="MachineToApplication" overrideModeDefault="Allow"/>
Add the required FasterFlect.DLL used by Combres.DLL v2.1.0.0 to the application bin folder (shall download the full zip from Combres codeplex, because the required fasterflect DLL V2.0.3732.24338 cannot be found in fasterflect codeplex) and other DLLs. For convinience, use the full Combres.DLL (1,3MB)
Check that the DLL versions and public key tokens are configured correctly in web.config using tool, e.g. .NET Reflector
I understand that this error can occur because of many different reasons. In my case it was because I uninstalled WSUS service from Server Roles and the whole IIS went down. After doing a bit of research I found that uninstalling WSUS removes a few dlls which are used to do http compression. Since those dlls were missing and the IIS was still looking for them I did a reset using the following command in CMD:
appcmd set config -section:system.webServer/httpCompression /-[name='xpress']
Bingo! The problem is sorted now. Dont forget to run it as an administrator. You might also need to do "iisreset" as well. Just in case.
Hope it helps others.
Cheers
For me, it was all about setting up my web server to use the latest-and-greatest tech to support my ASP.NET 5 application!
The following URL gave me all the tips I needed:
https://docs.asp.net/en/1.0.0-rc1/publishing/iis-with-msdeploy.html
Hope this helps :)
I had this problem with a brand new web service. Solved it by adding read-only access for Everyone on Properties->Security for the folder that the service was in.
I had the exact same error. It turned out that it was something was caused by something completely, though. It was missing write permissions in a cache folder. But IIS reported error 0x8007000d which is wildly confusing.
I have the same problem when I was trying to publish asp.net core 5.0 web app on my local IIS and the solution was to add the following inside System.webserver tag in my web.config file
<applicationInitialization doAppInitAfterRestart="true">
<add initializationPage="/" />
</applicationInitialization>
Reinstalling ASP.NET Core Runtime - Windows Hosting Bundle Installer made the trick for me... I belive the "ASP.NET Core Module" was missing.
For me I had a web.config file in one my root folders, this config file was for the live server so removing it allowed the site to run on the dev server.
So check for any web.config files in folders too.
In my case, i have installed dotnet hosting but error change to HTTP Error 503. The service is unavailable, but after install windows update KB2999226 and dotnet sdk, its work!
follow the procedure chronologically or it might fail due to missing or errors in redirecting.
install Runtime bundle e.g.. dotnet-sdk-7.0....
2.turn asp services on and internet services"Turn Windows features on or off" to enable IIS
3.install web hosting bundle iis 7.0 e.g dotnet-hosting-7.0.2...
this worked for me

Resource file is not working properly on IIS

I have 2 resource file.. one is default for english and another one is for chinese.
The web app is working fine with VS but when I published it on IIS its not showing chinese language.
I tried other solutions available on stackoverflow but nothing seems to work yet.
I can find resources.dll inside zh(bin) folder on IIS.
Is the error because of there was only one designer file generated that is Resource.designer.cs or something else.
I have made the required changes in Resource File properties like making the class public and build action.
IN web.config I changed
<globalization enableClientBasedCulture="true" uiCulture="en-US" culture="en-US" />
from false to true.
Please ask if Any other information needed to solve this issue.
Please give me some advice on this.
When I published it in the beginning the App_GlobalResources didnt get copied on server. I was able to see a resource dll for chiese in bin folder on server but it was of no use I think. doing republishing of website on my server after some changes, got me the desired result. here are the things that I changed -
I went to properties of resource file and changed -
Build to - Content
Copy to output directory - copy always
custom Tool- PublicGlobalResourceProxyGenerator(made both resource
file public)
and then in web.config I changed
<globalization enableClientBasedCulture="false" uiCulture="en-US" culture="en-US" />
to
<globalization enableClientBasedCulture="true" uiCulture="en-US" culture="en-US" />
Then I published it and got the chinese option working.

'The controller for path '/favicon.ico' was not found...' error

We're building an ASP.NET MVC 4 app in Visual Studio 2015. The app uses Elmah.MVC for exception handling. We're three developers; for two of us it's working fine on localhost, but one developer is getting this error (captured by Elmah):
The controller for path '/favicon.ico' was not found or does not implement IController.
This post provides a solution, and I've modified the routes to include it and the developer in question has synced his code:
routes.IgnoreRoute("{*favicon}", new { favicon = #"(.*/)?favicon.ico(/.*)?" });
Now nothing shows up in Elmah but the user continues to see a generic error:
500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed.
What could be going on? Thanks.
Update 1: Ripped out the Elmah stuff from Web.config and just had the developer load the app. It gets into an infinite loop trying to authenticate the user, similar to this.
We're using OWIN-MixedAuth, and the issue is more than likely on the IIS Express settings. I'll have the developer try it tomorrow and confirm:
Highlight the project in Visual Studio
Open the 'Properties' panel on the right (or press F4)
Set 'Windows Authentication' to 'Enabled'
Set 'Anonymous Authentication' to 'Enabled'
As the name suggests, it's mixed auth, so both types of authentication have to be enabled.
Update 2: The OWIN-Mixed Auth issue has been fixed. Now, it has something to do with these three HTTP modules in Web.config used by Elmah:
<httpModules>
<add name="ErrorLog" type="Elmah.ErrorLogModule, Elmah" />
<add name="ErrorMail" type="Elmah.ErrorMailModule, Elmah" />
<add name="ErrorFilter" type="Elmah.ErrorFilterModule, Elmah" />
</httpModules>
When we comment them out, the one developer is able to get onto the site. What do these modules do? Why would they cause a problem?
Finally resolved the issue. We had to make two changes:
We're using OWIN-MixedAuth, and part of the issue was on the IIS Express settings (under "Development Server" section):
Highlight the project in Visual Studio
Open the 'Properties' panel on the right (or press F4)
Set 'Windows Authentication' to 'Enabled'
Set 'Anonymous Authentication' to 'Enabled'
Another part of the issue: a corrupted applicationhost.config file used by IIS Express:
Ensure you're showing hidden files in Windows Explorer.
Go to the root of your project via Windows Explorer.
Open the hidden .vs folder.
Go to config > applicationhost.config, make a backup, and open it in Notepad (Notepad++ is better).
Compare it to a working applicationhost.config file from one of our machines. We found lots of old sites that were listed in the config file which were not being used anymore.
Once cleaned up, launched the app and it worked.
Add this to your global.asax file.
routes.IgnoreRoute("favicon.ico");

Ajax FileUpload Route/Querystring - DirectoryNotFoundException

I have a WebApp with an upload section.
To upload the files to a sql database I'm using a Ajax Toolkit Fileupload control.
I always get a similar error as in this post, but after hours of testing, I figured out what is causing my Problem.
My upload control is located on the SidDetails.aspx page and if open the page directly
with
foo.com/Pages/SID/SidDetails.aspx
I'm able to upload files.
but if I access the page via the route
foo.com/SID/My/1
I get a 500 internal server error
So I checked the link of the page that is causing the exception
foo.com/SID/My/1/?contextKey={DA8BEDC8-B952-4d5d-8CC2-59FE922E2923}&done=1&guid=BD327457-2013-1E97-6ADE-28612D63758E
For me, it looks like that is the problem, but I don't know how to fix this.
I already tried adding a route with query value
But i don't know if this is how you would approach it.
Could not find a part of the path 'C:\Windows\TEMP_AjaxFileUpload\E0E386A6-F5B5-1012-F6E5-1872E4D6EF69'.
Thats the exception that is thrown by the upload control.
I would like to keep the routes but how can I fix the problem?
I'm using Visual Studio 2012, .net 4.5 and AjaxControlToolkit 7.0930
Kind regards
CarnVanBeck
I run into this too, and after going crazy I fixed it.
Download the ajaxtoolkit source code project and open it.
Change the following row:
this._uploadUrl = 'AjaxFileUploadHandler.axd';
to:
this._uploadUrl = '/AjaxFileUploadHandler.axd';
Rebuild the project, get the new .dll and copy it to your /bin directory.
This will fix the issue, giving the right path to the handler.
PS: I came to this as:
I noticed some strange duplicated calls to the handler, happening only in routed paths
(like www.site.com/projects/edit/mypage), where uploads failed.
I noticed that in a test page, placed in the home dir of my site, the uploader was working fine.
Then I came to this page and noticed the mentioned row.
If your app is running in Integrated Mode pool, you have to add this lines in the web.config file:
<system.webServer>
<validation validateIntegratedModeConfiguration="false"/>
<handlers>
<add name="AjaxFileUploadHandler" verb="*" path="AjaxFileUploadHandler.axd"
type="AjaxControlToolkit.AjaxFileUploadHandler, AjaxControlToolkit" />
</handlers>
<validation validateIntegratedModeConfiguration="false"/>
</system.webServer>

MVC4 Bundles returns 404

I have a project that works with bundling when you run it from within visual studio. However, after you do a deployment, the bundling handler never seems to pick up the route. It ends up going to the static file handler instead, which returns a 404 response.
Any ideas? I see the optimization assembly in the bin of the website under IIS.
It's using the 4.0 app pool and integrated mode.
I'm wondering if anyone has any ideas or suggestions?
Thanks
----- update based on questions -----
VS2012
targetFramework="4.5"
I also added some code into the view to show which modules were loaded and I can see the bundle module listed there.
BundleConfig is the default provided when using the Internet Application MVC4 project template.
The site is being deployed into the root. It's odd as when I set EnableOptimizations = true (due to running in debug mode via visual studio F5), it works perfect! I can navigate to content/css and it spits out the combined css.
I deploy it over and everything else works, but bundling!
I've just hit (and solved) this problem.
Make sure your bundle's virtual path can't be confused for an existing directory or actual file name. In my case, I'd coded it as:
bundles.Add(new ScriptBundle("~/bundles/main.js").Include( ...
But when I changed it to
bundles.Add(new ScriptBundle("~/bundles/main").Include( ...
it all started working.
Updated Answer on 11/17/2013
This is caused by the fact that the default MVC routing only handles * instead of * . *, i.e. IIS or IIS Express's applicationhost.config has the following:
<add name="ExtensionlessUrl-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" responseBufferLimit="0" />
So to workaround it, we can add the following to the web.config:
<system.webServer>
<handlers>
<add name="UrlRoutingHandler"
type="System.Web.Routing.UrlRoutingHandler,
System.Web, Version=4.0.0.0,
Culture=neutral,
PublicKeyToken=b03f5f7f11d50a3a"
path="/bundles/*"
verb="GET"/>
</handlers>
</system.webServer>
For more information, you can reference the following:

ASP.NET MVC Url Route supporting (dot)
Old wrong answer:
Basically, DOT is generally not allowed in virtual path when IIS parse URLs.
This a Link mentioned the following URLScan AllowDotInPath parameter:
By default, this option is set to 0. If this option is set to 0, URLScan rejects any request that contains multiple periods (.). This prevents attempts to disguise requests for dangerous file name extensions by putting a safe file name extension in the path information or query string portion of the URL. For example, if this option is set to 1, URLScan might permit a request for http:// servername/BadFile.exe/SafeFile.htm because it interprets it as a request for an HTML page, when it is actually a request for an executable (.exe) file with the name of an HTML page in the PATH_INFO area. When this option is set to 0, URLScan may also deny requests for directories that contain periods.
Even I got the same error.
Adding <modules runAllManagedModulesForAllRequests="true" /> under <system.webServer> in web.config file solved the problem.
I had the same problem even with sample MVC application. I saw the default template bundles the style-sheet with css name which i guess IIS does not likes resulting in 404 error.
Changing the bundle name from css to APPCSS will resolve the issue for me.
