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."

I developed a test .NET Core Web App to which I added the .doc to .pdf conversion tool GemBox.
Their documentation for Azure deployment combined with .NET Core is limited to non-existing and their support guys could not help me with a clear solution either.
The error I get:
HTTP Error 500.31 - ANCM Failed to Find Native Dependencies Common
solutions to this issue: The specified version of
Microsoft.NetCore.App or Microsoft.AspNetCore.App was not found.
I tracked down the problem to the following issue:
GemBox.Document for .NET Core 3.0 uses WPF.
Is it possible that App Service added a limited support for WPF?
Thanks,
Lorena
The latest released version of GemBox.Document have cross-platform support for saving to PDF which doesn't have a WPF dependency, see the release post or the ASP.NET Core example.
So, you can now use GemBox.Document on Azure services, such as App Service, Azure Functions, etc. without any issue.
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 have some issues deploying a Silverlight 4 application on a remote server machine. My application consist a Cosmopolitan theme (a master/child page model) that connected with 2 services to retrieve specific information.
The first service is pretty simple. It is an asmx service that sends back the User Logon name to the Silverlight application.
The second one is a LinqToSQL service that relay some information to some autocompletebox and search tool.
I have developed the application on my machine using a local SQL server. When I am testing locally with an address type like this one (http://localhost:4080), it is working perfectly. But when deploying on the server using the domain name, it is giving the error saying that the remote server returned an error: NotFound.
I followed and review every steps on of deployment but I still have a problem. I try by all means to find a solution to this problem. Of course go through the list of prerequisites provided on these sites:
http://msdn.microsoft.com/en-us/library/ff426912%28v=vs.91%29.aspx
First, I tried myself to deploy the application without having to disturb my network administrators that by installing the required dll’s in the Bin directory of my project. I have installed those 3 dll’s (System.ServiceModel.DomainServices.Server.dll, System.ServiceModel.DomainServices.Hosting.dll and Microsoft.ServiceModel.DomainServices.LinqToSql.dll). Of course, nothing worked.
I then ask the network administrator to install the WCF RIA services. Does he have to configure something other than installing the WCF RIA services? Is this service including the Microsoft.ServiceModel.DomainServices.LinqToSql.dll.
I suspect that my problem comes from a configurations file: ServiceReferences.ClientConfig or Web.config. But I have included the exact same information from the MSDN site of deployment so I do not see where my problem might be. Am I using the wrong technique to publish the project? I am publishing the site using the File System method and then after modifying the config file to point to the right domain name.
I am able to reach the services by typing the http://domainname/ MeritService1.svc. It is telling me that I can test with the svcutil.exe or slsvcutil.exe. Will I lose a lot of time testing this?
By the way, Fiddler does not give much information accept a 500 error code.
It seems that many developers have the same problem themselves but I do not know where to aim! Anybody have a clue?
Here are the specs:
Local machine: Windows XP,
Browser: IE8 with Silverlight
Server Machine: Windows 2003 with IIS 6, .NET 4.0 and WFC RIA installed.

WCF RIA Services - “Not Found” Error Message
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.
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.
