I have the wcf service package, waiting to be put in IIS. Everything goes fine when I create a virtual directory on the default website and etc. But when I try to access the path in Chrome I get an error:
It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS.
When I comment this section:
<serviceHostingEnvironment aspNetCompatibilityEnabled="true"
multipleSiteBindingsEnabled="true" />
I can access the directory but not the service. Any idea?
I tried a little more and figured out what I was doing wrong. I can't create an virtual path under the Default Website. I had to create my own site, which appoint to the folder where my WCF files are storage. Something like this:
appcmd add site /name:WcfService1 /id:2 /physicalPath:C:\WcfService1 /bindings:http/*:8080
This way the virtual directory will be marked as an applicattion and everything will work just fine.
I'm currently struggling with httphandlers in IIS.
I'm developing a website in .NET4 in VS2010 and Cassini. In this website, i have a gallery, whose pictures are loaded through my handler.
For example http://mywebsite.com/Gallery/123/Pic1.jpg
My HTTP Handler gets the id 123 and returns the picture from the database (simplified).
So, everything works fine in Cassini (VS integrated webserver) and in IIS7 in "integrated mode". Pictures are loaded like they should.
But I have to deploy this site on a shared hoster, who is using IIS6.
After many searching and own logging, I found out, the the request isn't routed to my handler, and so I get a 404 from IIS.
My definition which is enough for IIS7 integrated mode:
<system.web>
<handlers>
<add verb="*" path="Gallery/*/*" type="[coorect Type spec]" />
</handlers>
</system.web>
For IIS7 in classic mode I had to add
<system.webServer>
<handlers>
<add name="ImageHandler" verb="*" path="Galler</*/*" type="[type]" modules="IsapiModule" scriptProcessor="c:\windows\Microsoft.net\framework\v4.0.30319\aspnet_isapi.dll"/>
</handlers
</system.webServer>
This last config only works whith the stuff in the module and scriptprocessor attributes...
But this config doesn't work in IIS6....
Can anyone help me ?
The issue is that IIS6 typically decides what ISAPI handler to pass the request to by using the file extension. So it sees .jpg and tries to serve a static file from that path. This is also what IIS7 refers to as classic mode. And you'll note you are referencing aspnet_isapi.dll in your configuration because it needs to be told what should handle this. Once you've passed it into aspnet_isapi, the asp.net http handling pipeline kicks in and you can execute your handler.
The easiest fix would be to find a host that supports IIS7. Failing that, you could see if they have any url rewriting options. With that, you could rewrite things so that you append an .ashx on the url, which will let IIS6 grab it and put it into the asp.net pipeline and your handler would fire. You could also see if they allow wildcard mappings, but that is a very tall order for most shared hosts.
I am developing a simple wcf service for test. When I test this service with my local IIS 7.5, then it works properly. But when I host it in web IIS, I receive this error:
The type 'WcfServiceLibrary1.Service1',
provided as the Service attribute
value in the ServiceHost directive, or
provided in the configuration element
system.serviceModel/serviceHostingEnvironment/serviceActivations
could not be found.
And my ServiceHost is:
<%# ServiceHost Language="C#" Debug="true" Service="WcfServiceLibrary1.Service1" %>
Please help me resolve this problem
Because I couldn't find this suggested in any of the questions I looked through for this, adding my case here:
I had this problem when I manually changed the namespace in the file MyService.svc.cs, and did not change the Service name in the corresponding file MyService.svc - turned out that it needed to be Service="namespace.classname".
Try using the assembly qualified type name.
This is [Fully Qualified Type Name], [Assembly]
Where [Fully Qualified Type Name] is, in the most common cases YourNamespace.YourType
And [Assembly] is, in the most common cases YourAssemblyName, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null
It gets more complicated than this (generic types, nested types etc) - but unlikely to be so in your case.
If your application is using the default build options, then I'm going to hazard a guess that the directive should be something like this:
<%# ServiceHost Language="C#" Debug="true"
Service="WcfServiceLibrary1.Service1,
WcfServiceLibrary1,
Version=1.0.0.0,
Culture=neutral,
PublicKeyToken=null" %>
Although you'll probably want to get rid of the newlines there.
Also, make sure your dll has actually been deployed
I had the same issue only when publishing my service but it worked locally.
It turned out to be that the service was referencing a DLL that wasn't being deployed. It's a super special case because it was a system dll (System.Web.Helpers) and thus the project didn't even have a reference to it and thus the "Copy Local" wasn't set to true.
IIS defaults to expecting to see the svc file in the virtual directory, and the binaries inside a bin folder (as marc_s commented).
However, the default build configuration for WCF Library projects is to build inside a bin/Debug folder (or bin/Release). You can change the Output Path to 'bin/' on the project properties Build tab.
Changing this resolved this error for me today.
I had this same problem after I deployed a working service to a new location (new site) in IIS. In inetmgr under the Default Website tree, I hadn't right-clicked the new site and selected Convert to Application - all working now!
Finally my problem solved.
I removed the service directory in my host and created a new virtual directory in the host space. Then I copied my service in new directory where I created it.
Now I can browse the .svc file for service and my client will consume the service.
I don't understand why this problem occurred! I am a little confused!
The answer marked as answer is very difficult to understand. In fact, although it led me to solve my similar problem, I don't know if that's because I accurately understand what the writer was meaning.
I was finding if I pointed an IIS application on my development machine to the actual project directory in which resides the web.config, MyService.svc, and bin folders necessary for the WCF Service Application it just wouldn't work, and was throwing this error. This is despite quadruple checking every setting and ensuring that things were equivalent to other simple, working WCF Applications.
Ultimately, I solved the problem by publishing to a different directory rather than depending on the project files and directory themselves.
Perhaps it was because the files were open in Visual Studio as I was trying to run the WCF application through IIS? I don't know, but the Visual Studio provided localhost:59871/... was working. I don't know if that instance is using the project files or a temporary published version.
Check whether namespace and class written in "Service" of "SeviceHost" is correct .It should be Service="namespace.classname" .
Another reason for this issue is often when a wcf service is moved from one directory to another, and the svc file has not been updated... easiest solution is to double check your .svc file and make sure the service definition is defined correctly.
As I can't up vote #jeromeyers answer at the moment, I want to add that this is the solution that I found for this issue.
Someone had copied and pasted a svc file and associated contract and code files to a new project, but they had not updated the namespaces and class names everywhere. Very frustrating tracking this down as it started with this error :
" name was started with an invalid character. Error processing resource 'file:///C:/...
<% #ServiceHost "
when trying to right click on the .svc file and doing "View in browser".
Even though this is slightly different than the question (not web iis): I got here through search because I was getting this error trying to Debug my service -- if you have multiple services inside a single solution, this error will occur if the solution in question is not built yet, and therefore the DLL not created when you try to access it. So to anyone out there make sure if running locally that the entire solution is built!
had this problem running a test project that was embedded in my solution.
I had to view in browser, then copy that link to a new service reference (delete the old one) then paste it in rather than using the discover utility button in the service reference.
Strange as well, after looking and trying others suggestions, i was still getting the error saying the:
The type ', provided as the Service attribute value in the ServiceHost directive, or provided in the configuration element system.serviceModel/serviceHostingEnvironment/serviceActivations could not be found.
Sure we all get large project with a lot of DLLs. Turned out some of the older components in my solution were targeting .Net 4.5, and newer dll were build with 4.5.1. When the 4.5 dlls referenced the 4.5.1 dlls .... Not sure why i was the happy little guinea pig to be the first on my team to find this. While the fix was obvious and easy enough, just all the dlls to target the same .Net runtime.
Just wish Visual Studio would notice DLLs within the same solution should all target the same .Net runtime and generate a warning/error when building especially with we have a solution and a project reference and the runtimes don't match...
Be sure your compiled dlls are moved to service(IIS directory)
directory.
For example, sometimes Jenkins doesn't move them automatically.
I had the same issue when i uploaded my working localhost service to a new location on host.
I create a new Virtual Directory and published my Service to it via Visual Studio(FTP). Problem Solved.
It happend the same to me and the solution was creating a forder named "bin" and place the dll inside of it. Then, refresh the website on IIS and that's all
I had this problem too, and what did the magic for me was to restart the IIS.
This is a very weird error.
First time hosting WCF Service Application, in IIS ?
Many have solved their problems one way or the other. However if everything is your solution is correct and your error is about host your app in IIS, then ensure your physical path in IIS when you add your website is pointed to the "bin" directory of your solution as seen below in the screen shots.
Please look at https://msdn.microsoft.com/en-us/library/ms733766(v=vs.100).aspx
You need to do 2 things to be able to Host the Service on IIS, or even on Visual Studio's itergrated IIS_EXPRESS.
1) Update the Web.Config to include ServiceActivations
change:
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
to
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true">
<serviceActivations>
<add service="API.Service1" relativeAddress="Service1.svc"/>
</serviceActivations>
</serviceHostingEnvironment>
2) You need to create a directory called App_Code in the root directory.
You now need to move the Service (ex: Service1.svc) from the root directory into the App_Code directory.
So you will have App_Code\Service1.svc
If you browse the Service
http://localhost:63309/Service1.svc it should work.
on the web application, I am using a NHibernate helper that looks up the session that was opened in a httpmodule (and committed there also).
<property name="current_session_context_class">web</property>
In the console application, what do I do?
Your options are: "call" & "thread_static". Have a look at this for more detailed explanation on all available contexts:
http://nhibernate.info/doc/nhibernate-reference/architecture.html#architecture-current-session
In order to have your library work for both a web and a console application you have two options:
Based on a application setting in the App.config and in the web.config have the Session Factory built accordingly by setting the current_session_context_class property manually in the code and remove it from the hibernate.cfg.xml file.
Include a in the web application's web.config and in the app.config of the console application. This way you can have the current_session_context_class property set to different values. If I am not mistaken the in the web.config and in the app.config overrides the values of the hibernate.cfg.xml. If I am wrong then you will just have to include in the web.config and the app.config the complete and remove the hibernate.cfg.xml file from your library.
