Trying to use a DLL that returns a list of tasks in the W2k3 server's Task Scheduler. Works great when I use it in a C# console app on the server, and using it on my computer (ASP.NET Dev Server), but when doing the same thing through the Silverlight-WCF RIA on the W2k3 server, it just wouldn't go. Silverlight returned "Object reference not set to an instance of an object" whenever it calls that DLL.
Fired up the Service Trace Viewer:
System.ServiceModel.FaultException`1[[System.ServiceModel.DomainServices.Hosting.DomainServiceFault, System.ServiceModel.DomainServices.Hosting, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35]], System.ServiceModel, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089
Might it because I'm using a DomainService class, its hiccuping? Any particular security permission or config on IIS that needs to be done?
update:
Tried one last thing .... Identity impersonation to my domain username and password works! So what is the best way to set up IIS to get this to work?
Just stuck with using a Windows dummy account using identity impersonation. Don't like it, but it works.

I have a WCF self-hosted service, using NetTcpBinding with callbacks and transport security on Windows Azure, with a production certificate and a domain redirect.
Before renewing my developer license, everything worked. After, I'm getting this exception in the Reference.cs file:
The type 'Microsoft.VisualStudio.Diagnostics.ServiceModelSink.Behavior,
Microsoft.VisualStudio.Diagnostics.ServiceModelSink, Version=4.0.0.0,
Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' registered for extension
'Microsoft.VisualStudio.Diagnostics.ServiceModelSink.Behavior'
could not be loaded.
My colleague has yet to update her dev license, and everything still works for her.
Any idea why this is happening ?
Deleting the project and re-downloading it from source control solved the problem. No idea what happened...
I'm try to work on WCF to sync the mobile database with server database. I was using this tutorial. When i try to debug I got 'File or assembly name 'System.Data.SqlServerCe, Version=3.5.0.0, Culture=neutral, PublicKeyToken=3BE235DF1C8D2AD3', or one of its dependencies, was not found.'. I try to remove the reference and add again but still the same.
Below is the screen short of System.Sata.SqlServerCE.
Over a year ago I had been working on a WCF service, which I wrote using VS 2008. It runs under a Windows service, which I also wrote. It’s been running there ever since. And unfortunately, other projects/priorities have come up, preventing me from continuing with that project, until now.
Now I’m trying to get back to it. However, this go around I’m trying to find out if I can use VS 2010 and .NET 4, instead of .NET 3.5. I’ve brought up the command prompt, to run SvcUtil, to get the wsdl information, which I’ll put into the config file for the new WPF app I’m trying to get started writing. Only thing is, I keep getting an error, saying that I can’t reach the server, etc.
So, I copied the .exe.config file from the server to my machine, where I could edit it with SvcConfigEditor. I’ve made those changes, put it back onto the server, and got an error while trying to run SvcUtil, but worse than that I didn’t see the .svclog files I expected to see. So I got into the server’s Services app. I found the Windows service I wrote a year ago; saw that it was running, and stopped and started it again.
Now I’ve got a different problem. My Windows service starts, but then stops immediately. I get this message saying that the service had started and then stopped, and saying that sometimes that happens with different sorts of services, like Performance Logs and Alerts services. I’ve checked the event log on the server, and then only thing there related to this Windows service is that it entered the start state and then entered the stopped state.
Ah, after attempting to start it 4 times, it finally gave me an error in the event log! (Why didn’t it do that in the first place? And who says that trying to do the same thing over and over again, and expecting different results is a sign of insanity, when clearly the first 3 times it didn’t register anything in the event log, but on the 4th try it did.)
Here’s the error:
Event Type: Error
Event Source: Service1
Event Category: None
Event ID: 0
Date: 5/4/2011
Time: 10:14:46 AM
User: N/A

and here’s the new section of code put into the .config file by SvcConfigEditor:

This question was answered in the comments but there is a gotcha that I've seen in Visual Studio 2010 that could result in a similar situation.
Even if the target framework is set to version 3.x for a WCF project, using the 2010 SvcConfigEditor will automatically insert "System.Diagnostics.XmlWriterTraceListener, System, Version=4.0.0.0..." although it should be inserting "System.Diagnostics.XmlWriterTraceListener, System, Version=2.0.0.0..." This will bite you when deploying the altered web.config to an IIS hosted service where the AppPool is not configured to use the .NET 4.0 framework. The fix is simply edit the web.config back to "Version=2.0.0.0".
I'm working with a WCF service in Azure, which uses Windows Live ID authentication with the recent deviceid requirements. When I host my WCF service locally in the compute emulator, it works properly, but when I deploy the cloud service to Azure and call it the same way (from another project that uses the WCF service as a service reference), I get the error:
Could not load file or assembly 'Microsoft.IdentityModel, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.
I found this post : http://social.msdn.microsoft.com/Forums/en-US/netservices/thread/cd139b5c-ad12-4298-af2f-1b2d0136a977
But there are a few problems:
1. I don't seem to have access to Microsoft.IdentityModel, only System.IdentityModel. I'm not sure why it's searching for something in 3.5 at all, as I'm building in .NET 4.0.
2. When I choose to "copy to local" on System.IdentityModel, it doesn't change anything.
Any help? I would appreciate it!
Best Regards,
Andy
The answer to this question is here: http://social.microsoft.com/Forums/en-US/crm2011beta/thread/951f97df-77b8-4659-8032-6a71161a730c.
The CRM 2011 Beta SDK (versions after Dec. 15th) have some helper code that registers the deviceid on Azure. If you're not working with Microsoft Dynamics CRM 2011, the helper code can still be used to help you see how it's done.
I am developing an application based on .Net Framework 3.5 sp1 and hosted on windows server 2008(64bit).
While browsing wcf service (.svc) locally every things is ok but while browsing with full domain URL, it got an error.
local address is like this: http://localhost/MyService.svc
and domain address is like this: http://MySite.ir/MyService.svc
by the way pages (.aspx) and other files work correctly both on localhost and with domain address.
any Idea would be appreciated
Here is detailed error:
HTTP Error 404.3 - Not Found
The page you are requesting cannot be served because of the extension configuration. If the page is a script, add a handler. If the file should be downloaded, add a MIME map.

Please make sure you've activated WCF components from here.
Or alternate and easy way is, go to control panel -> Turn Windows feature on or off -> and make sure you've all the options ticked as mentioned in below screenshot.
You might need to activate each box and accept in case you get errors when activating all features at once
OK, here is the answer:
Go to Handler Mappings | Add Handler Manager --> And then add below information
Request Path: *.svc
Type: System.ServiceModel.Activation.HttpHandler, System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089
Name: svc-Integrated
If anyone has this issue on Windows Server 2012, Bill Moon's answer here solved it for me:
"For Windows Server 2012... From the Server Manager, click on Add roles and features, select the appropriate server, then select Features. Under .NET Framework 4.5 Features, you'll see WCF Services, and under that, you'll find HTTP Activation."
I have windows 10 in my laptop and using visual studio 2015 for WCF development. WCF is running fine in visual studio but when hosted in IIS I got the same error.
I checked IIS handler. svc extension was missing. So I tried to add new handler in IIS as suggested by Mori in first answer. I didn't find type "System.ServiceModel.Activation.HttpHandler".
So I opened "Turn windows features On or Off" and installed features as highlighted in screen shot.
This worked for me.
If you're using .Net 4.x, the PublicKeyToken is 31bf3856ad364e35.
However, following this post about installing WCF Services properly in IIS, the handler was set up for me.
I wanted to add this as a comment to the answer but didn't have enough rep for it. I tried running ServiceModelReg and aspnet_regiis.exe with various flags and added HTTP Activation feature but it still didn't work. Even using the Handler mapping UI in IIS didn't work since it could not find System.ServiceModel.Activation.HttpHandler. What finally worked was adding the handler Mori mentions manually to my web.config file.
<system.webServer>
<handlers>
<add name="svc-Integrated" path="*.svc" verb="GET,HEAD,POST,DEBUG" type="System.ServiceModel.Activation.HttpHandler, System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" modules="ManagedPipelineHandler" scriptProcessor="" resourceType="Unspecified" requireAccess="Script" allowPathInfo="false" preCondition="integratedMode" responseBufferLimit="4194304" />
My project was running .Net 3.5 and IIS 7.5 on Windows 7 and IIS 7.0 on Win Server 2008 R2.
Try unchecking WCF HTTP activations from "Turn Windows featured on or off" window (See here) and re-install by going to
%windir%\Microsoft.Net\Framework\v3.0\Windows Communication Foundation\
and execute ServiceModelReg -i
