Silverlight 4 Hosting - ASPHostPortal :: Deploying a Silverlight 4 Application Connected to a Database

clock November 9, 2010 09:08 by author Jervis

This article shows how to deploy a Silverlight application 4 connected to a database. We are going to use IIS 7.5 to do it.

This is the error message:

"System.ServiceModel.DomainServices.Client.DomainOperationException: Load operation failed fore query 'GetProducts'.... Failed to generate a user instance of SQL Server due to failure in retrieving the user's local application data path. Please make sure the user has a local user profile on the computer. The connection will be closed"

And I assume that you have finished your Silverlight app using VS 2010 and .NET Framework 4.0. We have a few views and an MDF database in our App_Data folder. It would look like this:



Now, we are going to deploy our application. You can see this figure below:



This will open up a dialog window. We can create publishing templates. Let’s just choose the location where we are going to publish our application (our computer, a web server, FTP…). I like to check the “delete existing files in the destination folder before publishing” option. Click the Publish button.

Now we are ready to work with the IIS configuration (I'm using Windows 7).

Let’s open the Windows Start Menu, and type “inetmgr” in the search box. The IIS Manager Window will show up.

Go to the MIME Types.



In the appearing list, we’ll need to include the following types (XAML, XAP, XBAP) as shown in the image below:



Now, in the left menu, let’s go to Sites, and let’s add our Web Site (as default site, virtual directory… based on our own needs). When done, let’s click in our application, like this:



In the menu that appears on the right side, we’ll click the “Advance Configuration” link. Now, in the dialog, we’ll click in “Application Group”, and you’ll notice that a button with three dots will appear on its right. Click that button and you will see another dialog. Select ASP.NET v4.0, as shown in the image below:




If ASP.NET v4.0 is not selected, and you leave
DefaultAppPool as I did in the beginning, you will get the following error message every time your application tries to connect with the database: “There is an error in the service with the Get function..”


So, now that we selected our Application Group, let us configure it. In the left panel (back in the IIS Manager Window), right above our Default Site, we’ll see “Application Groups”. Click it. A list will appear in the center panel. Let’s open the ASP.NET v4.0 and select the right framework version. Click ok and select it again, but instead of opening it, this time we’ll go to the right panel, and we’ll click on “Advance Configuration”:



Change the Local System and select Network Service, as shown in the image above. And that’s it! Now we are able to access our data from our Silverlight 4 application without getting any error from the Web Server.

Hope this post can help!!

Silverlight 4 Hosting - ASPHostPortal :: Error Message – Load Operation Failed for query “GetUser”

clock November 9, 2010 04:54 by author Jervis

Sometimes we get this error when running WCF RIA Services.

“Load Operation Failed for query “GetUser”
.

This is always an annoying issue with Silverlight deployment to do with connection strings and domain authorizations. Basically it’s a very generic error that pops up if you’re using the in-built standard asp.net model, such as the RIA services models of .net/silverlight development using aspnet authorization and registration.


Why it can happens?

1. Your development system is using a local SQL Express database which works fine when your on your own machine, but once its online, it’s still trying to find the same LocalSqlServer or localhost, and obviously cant. You can get round this in your web.config, using stuff like:
     <remove />    <add connectionString=”etc etc”.>

2. Or possibly you have all the connection strings point to the right places, but your new server database doesnt contain all the necessary aspnet tables/framework. Theres some tools that are located in your windows/.net folders, such as aspnet_regiis.exe, which if you search for online, you willl get details on how to use them to automatically configure/update an sqlserver with the all the necessary aspnet objects.

3. You haven not deployed necessary references to the webserver, especially ones such as the System.Web.Ria, System.Web.DomainServices and System.ComponentModel.DataAnnotations. You can select them in your visual studio project and mark the Copy Local propery to True.

4. Also if you have any services mapped from server to client, such as WCF Services, make sure when your publishing to update their bindings/endpoint addresses in the client, as they will be still looking for those services on the localhost development server.

5. Also make sure you use a valid crossdomain.xml and clientaccesspolicy.xml on your web project/deployment. If you do a websearch for these two filenames, you will get lots of examples of various settings to use that might be relevant to your site operation
.

And, you have to check your IIS settings that sometimes cause the issue, like allowed IIS authentications (anonymous, impersonation, forms, etc).

The other alternative that you can consider is you can use mix of setting of the correct IIS authentication allowing anonymous and forms, and making sure the default connection strings were update correctly. As for the stuff on our server, please (if possible) remove ASP.NET authorization from your application and please write your own custom authorization, so it’s not even trying to update the local sql server for the inbuilt ASP.NET stuff
.

Hope this post can help you.
