Problem with WIF and WCF Dataservices

Question

I'm running into a problem with the WCF dataservices loading in a different AppDomain when running in Azure. The WIF dll is working (other parts of the site also work, and copy local is true)

Because it's a different appdomain I get errors like:

Unable to find assembly 'Microsoft.IdentityModel, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.

SerializationException: Unable to find assembly 'Microsoft.IdentityModel, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.]
   System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage(IMessage reqMsg, IMessage retMsg) +4767763
   System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData& msgData, Int32 type) +1725

]
   <CrtImplementationDetails>.ThrowModuleLoadException(String errorMessage, Exception innerException) +50
   <CrtImplementationDetails>.LanguageSupport.Initialize(LanguageSupport* ) +169
   .cctor() +33

How can I fix this?

When adding an STS to a project and run in the cloud I get the error of

Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.1

Server Error in '/' Application.

Unable to find assembly 'Microsoft.IdentityModel, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.

 

Steps to reproduce error:

1) I took the hands-on lab "introduction to windows azure" and started with excercise 3, deployed to the cloud - works

2) Run the ADD STS wizard, change <deny anonymous> to <allow anonymous> deploy, receive error missing IdentityModel.dll

3) Add reference to microsoft.identitymodel.dll, set copy local to true, deploy to cloud, new error

 This seems like an Appdomain problem, how do I fix this?

Answer 2

Hi Erik. It might be useful to see if the Federated Authentication in a Windows Azure Web Role Application lab from the Windows Azure Platform Training Kit works. Running the lab’s dependency checker and setup script may tell you something.

Hi Erik,

>3) Add reference to microsoft.identitymodel.dll, set copy local to true, deploy to cloud, new error

What is the new error? Could you post a demo project that can reproduce this issue (work locally but failed after deployment to cloud)?

Hi Allen,

The new error is in my post above, just read it carefully, it looks like the .NET error "could not loud assembly", but this one has a stack trace with some remoting in it.

I used the standard GuestBook demo application from the WAPTK (intro to azure, exercise 3), NO code changes

Added an STS reference (to an appfabriclabs ACS)

and after the deploy (with copy local to true) I get this error.

Answer 5

Hi David,

In the Federated Authentication in a Windows Azure Web Role Application lab there are no calls to a WCF Data Service, just a simple page displaying some user information. I did this lab in the past and it works (just like all the labs in the WAPTK)

In the setup script is nothing special. And to fix my problem, you need a setup script running in the cloud...

Hi,

Just a thought, could you use elevated startup task to add this assembly to GAC? Does it work?

Answer 7

Yes, installing to the GAC makes it work, but that's just working around the problem.

That means that I need to register all components to the GAC.
Vittorio mentioned a new EULA which allows us to redistribute WIF with our app.

My question remains, WHY does WCF Dataservices use remoting and uses another AppDomain.

>That means that I need to register all components to the GAC.

Not exactly. I think only assemblies like this specific one need to be added to GAC.

>My question remains, WHY does WCF Dataservices use remoting and uses another AppDomain.

Please provide your implementation about the WCF Data Services and let me know where/how WIF is used. Some code snippet/config is required to answer this question.

It's exactly from the sample GuestBook_Data project:

 public IEnumerable<GuestBookEntry> GetGuestBookEntries()
        {
            var results = from g in this.context.GuestBookEntry
                          where g.PartitionKey == DateTime.UtcNow.ToString("MMddyyyy")
                          select g;
            return results;
        }

 public class GuestBookDataContext
        : Microsoft.WindowsAzure.StorageClient.TableServiceContext
    {
        public GuestBookDataContext(string baseAddress, Microsoft.WindowsAzure.StorageCredentials credentials)
            : base(baseAddress, credentials)
        { }
 
        public IQueryable<GuestBookEntry> GuestBookEntry
        {
            get
            {
                return this.CreateQuery<GuestBookEntry>("GuestBookEntry");
            }
        }
    }

WIF is configured (Add STS reference) but no other WIF code is used to trigger this error.

Could be that the WCF dataservices try to add the (WIF)securitycontext to the call and serialize that?

Hi Erik,

Could you send the repro project to me to test? My email is allenc at microsoft.com

Answer 11

Still not sure WHY WCF dataservices uses a different AppDomain, but the supported solution to add WIF to the GAC is through Windows Update:

Register this Startup task, together with the WIF msu file, set copy to output to true.

@echo off

sc config wuauserv start= demand

wusa.exe "%~dp0Windows6.1-KB974405-x64.msu" /quiet /norestart

sc config wuauserv start= disabled

Answer 12

We're experiencing this exception also, but we're not using using web services in our app. 

Our diagnosis so far has isolated the problem to calling RoleEnvironment.GetConfigurationSettingValue() in a web role deployed using Full IIS (as per http://blogs.msdn.com/b/windowsazure/archive/2010/12/02/new-full-iis-capabilities-differences-from-hosted-web-core.aspx).

The remoting is presumably the the interop between w3wp.exe and WaIISHost.exe.

Microsoft.IdentityModel is referenced with copy local true, so how is it that WaIIHost.exe cannot load/locate it?

Answer 13

Hello Erik, 

 

Can you walk me through or guide me to the steps that are required to register this startup task? 

 

I am getting "Unable to find assembly 'Microsoft.IdentityModel, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'" error while running the application which is deployed on Azure. 

The application works fine on Dev Environment and I've ensured that the Microsoft.IdentityModel has Copy Local set to true.

Thanks,

Harish

Answer 14

I got it. Thanks Erik.

Nice to hear you've got it working

I've also blogged about this solution here:
