I am new to Sharepoint. I wrote a simple RIA MCF silverlight app which runs all the queries right on my server. Now I tried make it available on a Sharepoint testing site. I loaded the xap file but Sharepoint throws me tons of load operation exceptions when it tries to load the app, apparently having problems with the EDM in the app. What do I need to do here? Is the xap the only thing I need to load on the shared documents folder?
Thanks.
Justin,
There are few steps you need to follow to load the Silverlight XAP in sharepoint.
You need to create RIA service as an independently hostable web application (.svc)
Follow the guidelines available here
Once you have the solution ready. Host service on IIS and make sure that it is functioning correctly.
Configure the .svc in the web.config of the hosting web application and access the same in your silverlight application as below
new LoggingContext(new Uri(ConfigurationManager.AppSettings["LoggingServiceUrl"]);
Load the xap on sharepoint site and in the configuration section provide links to .svc services.

Last year someone reported encountering this problem ("The Silverlight project you are about to debug uses web services. Calls to the web service will fail unless the silverlight project is hosted in and launched from the same web project that contains the web services.") and accepted the answer to "set the web project which hosts the Silverlight application to be your startup project."
I'm seeing the same message, but think the solution might have to be different. I am building in VS 2010 a Silverlight application to access the Google Weather API, with VB as the code-behind. The API will return a XML file with data for the specified city (ex., "http://www.google.com/ig/api?weather=london,england"). The Solution Explorer only shows my VB/Silverlight project ("GetWeather"), and the Project Properties dialog box shows the Startup Object as "GetWeather.App" -- the only choice. I'm trying to use a WebClient object to make the call and an XDocument object to parse the return. But I repeatedly get the above error message, with no other result. What am I doing wrong?
Thank you in advance!
I would add a simple Web project and configure it to host the Silverlight app. You'll need to host the app somewhere anyways, so why not create a stub ASP.NET application in your solution? The easiest way is to create a new Silverlight app solution selecting an ASP.NET web project as the host, and then copying your existing code to that solution. Then you should set the web project as the startup one. This should make debugging a lot easier.
Besides, do remember to configure the client access policy to enable cross-domain calls. Check out this article
I am trying to convert an existing silverlight application to use a MVC web application versus a regular asp.net web application.
I have taken a look at fiddler and it is not able to access the domain service methods as the service does not exist (this is because these files are autogenerated once they are called with ria services). But with MVC since it looks for the controller if files don't physically exist we are getting this error.
I have tried to ignore svc files by:
routes.IgnoreRoute("{allsvc}", new { allsvc = #"..svc(/.*)?" });
and also have tried;

With no success. Has anyone been able to successfully do this, if so, how?
Thanks in advance.
I'm attempting to deploy a RIA services 1.0SP1 project that has been precompiled with a Visual Studio 2010 Web Deployment Project. When I deploy the application to IIS using Visual Studio, the application runs fine. However, when I use a web deployment project to precompile the application, the first call to a RIA services service on the same system fails. An error similar to this is produced:
Load operation failed for query 'Login'. The remote server returned an error: NotFound.
It appears that the "NotFound" error happens frequently in RIA Services applications, as per this question. Using Fiddler, I discovered the error is a true Not Found error on the server, where as the service cannot be found. I also attempted to reference the URL of the service directly, which failed.
Searching the web, the comments on this post point to there being known problems with web deployment projects and RIA Services and this post points to the issue being a problem with Virtual Path Provider that RIA services uses to map the incoming requests to the proper domain service.
My question is, is it possible to get a RIA Services Web application working with a Web Deployment Project? Are there configuration changes required to make this work? One of the referenced sites mentions manually creating .svc files, is this the correct approach for solving the problem?
Here's what I could find. RIA does not support deployment in a Web Site project. This is an intentional decision that is evident in the tooling (you cannot add RIA to a new SL application that you're linking to a Web Site). My best guess is the precompiled deployment option can interfere with the execution of RIA's Virtual Path Provider.
I can't find anything that confirms the VPP will not run, but here are the sources that lead me to the conclusion.
1) From http://msdn.microsoft.com/en-us/magazine/cc163675.aspx
"Note that the .aspx files in the deployment directory are just marker files with no content. They have been left there to ensure that a file with the endpoint name is present in case the "Check that file exists" option for the .aspx extension in an IIS app is set."
2) From http://forums.silverlight.net/forums/t/218547.aspx#531318
"When you build and deploy your RIA services website using web deployment project then you have to copy a dummy page with .svc extension file under "ClientBin" or create a folder "Services" and paste the file there."

"If the [published] WebSite project does not work, go to the folder, delete the PrecompliedApp.config"
I am using a silverlight with wcf and when I use the .web project then it runs but when use the silver light project to run the following exception throws:
An error occurred while trying to make a request to URI 'http://localhost:9000/Services/BLWCFSvrc.svc'. This could be due to attempting to access a service in a cross-domain way without a proper cross-domain policy in place, or a policy that is unsuitable for SOAP services. You may need to contact the owner of the service to publish a cross-domain policy file and to ensure it allows SOAP-related HTTP headers to be sent. This error may also be caused by using internal types in the web service proxy without using the InternalsVisibleToAttribute attribute. Please see the inner exception for more details.
I want to use the silverlight project to debug my code
Thanks in advance
In order to access network resources from Silverlight, the domain hosting the resource must provide a client access policy file; this is designed this way for security reasons. See here for details: http://msdn.microsoft.com/en-us/library/cc645032%28VS.95%29.aspx
I think your problem is different that just having the clientaccesspolicy.xml, the fact that it runs under the web project, means that you are delivering policies, if you have those added as seperate files under the web project then they wont be deployed when you run the SL3 app seperately, but im sure you figured this out and you're delivering the policies via WCF using webHttp binding (RESTful style), if not, you should.
I think the problem is that when you run the webproject, it builds to your local IIS and executes from there, IIS will allow the SL3 app to communicate with ports/addresses different from the ones that the site is hosted on
when you run SL3 app natively, VS2008 auto generates a test html site for it to be hosted in with some default settings, and uses VS2008 built-in hosting service, which does not allow communication to an address/port different from that of the hosting address. (even though Silverlight is a client side library, VS2008 can do this)
so if you want to run the Silverlight application natively, meaning actually executing the XAP, you can deploy it to IIS, and configure IIS to deliver XAP files, or just install it and run it out of browser and let it update from IIS the deployed version
Just copy a clientaccesspolicy.xml file (for an example take a look at this post; you can even use this sample) into the root of your webserver (eg: c:\inetpub\wwwroot\).
This should help.
I have solution containing silverlight project, wcf service project and other projects of C# i want to have one app settings file from where all projects can load settings. Which will be useful in case of db interaction, logging etc..
Currently i m changing all app settings file in all projects.
I have used Nini successfully for some time now. It allows you to put all your config settings in a central file which can then be referenced from all your server-side projects, be it web applications, scheduled jobs, wcf services etc. For the Silverlight client apps, I created a WCF configuration service. All the different Silverlight apps access this service at startup to load their settings. This means that the server-side apps only need to know the location of the Nini configuration file, and the Silverlight clients only need to know the url to the configuration service (transferred through the in the .aspx page). The configuration service then accesses the Nini config file and returns a collection of ConfigurationSettingEntity objects. These just contain a key and a value. Of course it is of extreme importance to make sure that all sensitive settings (e.g. db connection strings) are never transferred over the configuration service. Nini allows you to divide your config file into sections. I have three sections currently. One for the Silverlight clients ("ClientSettings"), one for server-side settings only ("ServerSettings") and one that contains any shared settings ("CommonSettings"). This way you can make sure that the configuration service never returns anything from the ServerSettings section. This has worked really well for my purposes.
