Load operation failed for query GetUser

[Gerhard]

I have a Silverlight Business Application that runs fine in my development
environment, but in IIS I get a Load operation failed for query GetUser error
with details:

at System.Windows.Ria.OperationBase.InvokeCompleteAction()
at System.Windows.Ria.OperationBase.Complete(Exception error)
at System.Windows.Ria.LoadOperation.Complete(Exception error)
at System.Windows.Ria.DomainContext.CompleteLoad(IAsyncResult asyncResult)
at
System.Windows.Ria.DomainContext.<>c__DisplayClass17.<Load>b__13(Object )

This is on the same machine that the development is done on.

I set all except basic system references to Copy Local. I published using
copy all project files. Still get this error.

I'm on a Windows 2003 Server with all updates run on it.

How can I fix it to run through IIS?

Thanks.

You can probably get more info on the error using fiddler.
I would guess your problem lies in configuration of IIS.

In my case, it resolved with making the server admin that the Application
Pool was using and admin on SQL Server also. Doesn't make a lot of sense,
but it worked.

You're relying on windows authentication for database access?

In my case, it resolved with making the server admin that the Application
Pool was using and admin on SQL Server also. Doesn't make a lot of sense,
but it worked.

So, you're using Windows authentication on SQL Server, which causes IIS
worker process user account to be used? Maybe, you should be using a SQL
Server user-id and psw for the Entity Framework or Linq-2-SQL connection
string when creating the model. That way, you'll have no problems with logon
to SQL Server with the app.

Is not that ASP.NET and WCF RIA service cool? It has value that I can
introduce to my development team.

Hi, I am facing the exact similar error. Prior to hosting the app I did the following:
Copied the DLLs to bin folder.
Added <trust level="Full" /> to Web.config
Set connectionString as follows: <connectionStrings><remove name="LocalSqlServer" />
<add name="LocalSqlServer" connectionString="Data Source=<SQLSERVER>;Integrated Security=false;Initial Catalog=<DB>;User ID=<USERID>;Password=<PASSWORD>" providerName="System.Data.SqlClient" /> </connectionStrings>
Authentication <authentication mode="Forms" />
ASP Setting <serviceHostingEnvironment aspNetCompatibilityEnabled="true" />

Now when I have hosted the application on a server I am geting this Load operation failed for query 'GetUser' error.
On fiddler i can see a HTTP/1.1 500 System.ServiceModel.ServiceActivationException generating at response headers.
I have configured IIS on my machine and hosted the application there. I see the same error. But in my local machine fiddler shows a 404 not Found error at response headers. It also tells me the error occured while trying to access the AuthenticationService.svc/binary file.
Let me give an overview of my application structure.
I am using an ASP.net membership provider to handle custom user validating logic against my Database. and I have not done anything on my autogenerated AuthenticationService service. in my VS environment, everything is working perfectly. What I am doing wrong?
Please help.

Somehow I have missed a few lines. I have modified the connectionstrings as:
<connectionStrings><remove name="LocalSqlServer" />
<add name="LocalSqlServer" connectionString="Data Source=<SQLSERVER>;Integrated Security=false;Initial Catalog=<DB>;User ID=<USERID>;Password=<PASSWORD>" providerName="System.Data.SqlClient" /> </connectionStrings>

I Have a solution,
