I have hosted my silverlight service on the server. I have created a client application on my local machine referencing the silverlight service on the server. Everything compiles and work fine.
Now I coped the xap file into another silverlight application and tried to read the xap using the following code.
StreamResourceInfo _streamResourceInfo = new StreamResourceInfo(e.Result, null);
StreamResourceInfo _streamResourceInfoDll = Application.GetResourceStream(_streamResourceInfo,
new Uri(string.Format("{0}.dll", abc), UriKind.Relative));
AssemblyPart _assemblyPart = new AssemblyPart();
Assembly _assembly = _assemblyPart.Load(_streamResourceInfoDll.Stream);
UserControl _userControl = _assembly.CreateInstance(string.Format("{0}.MainPage", abc)) as UserControl;
this.Main_Canvas.Children.Add(_userControl);
Everything works fine. Now I added Navigation Framework to my application.
I modified the main page with navigation framework. In my main page I have
<navigation:Frame x:Name="ContentFrame" Source="/Views/abc.xaml" Grid.Row="1" >
When I Copy the modified xap on to the other application. It complains No xaml is found at the location /Views/abc.xaml.
Any help will be highly appreciated.
This answer is pretty comprehensive
But... if dynamic XAP loading is your thing, do yourself a favour and take a look at Jounce - It's an MVVM framework, but that doesn't mean you absolutely must use ViewModels.

I am totally to Silverlight and am Getting started. I finished the first of the Getting started series here and now seeing into HTML Bridge now over here. Visual Studio created a website for me when it created the new silverlight application. For the HTML bridge tutorial I created another silverlight page(Is this what i should create) and put some code into it.
Question
How do I embed this into a html page? ( I know how to do it using markup as well as javascript, I am confused as to how to get the application out of single xap file inside ClientBin directory)
With Silverlight you are dealing with a single plugin within a HTML page. That plugin is the single XAP file that the HTML page downloads.
Your Silverlight app may also have many pages, but its navigation is not the same as HTML navigation (it uses bookmark URLs to fool the browser into staying on the same page while it changes content). There is only the one HTML page involved.
Initially, just to test your new page, you can change the app.xaml.cs file to create your new Silverlight Page instead of RootVisual = new Main() etc. Long term you need one Silverlight application per separate plugin your require.
Update (from comments):
Pages in Silverlight are changed by substituting a visual element of the single main page with the contents of another Silverlight page.
You cannot simply replace the RootVisual (as that can only be set at startup).
Start with a new Navigation or Business application project to see the basics (navigation adds a lot of complexity, but once you see how it works it is pretty cool).
I have a Silverlight app made in Visual Studio 2010 and I want to put it on a website but I don't have the slightest clue how.
I've looked at all the msdn documentation and they all mention a .xap file that is the file you use on the website but there is no .xap and I can't find out how to compile my code into a .xap file.
Also, when I run the App and look at the source in the browser, it has my code compiled into the .xap file, but there is no .xap file!
So my question is simply how do you go about getting a Silverlight app on a website because I've been trying for hours and I can't figure it out.
A sample html or aspx page is included when you create the solution. This is the page that the browser navigates to when you hit F5. You can take that page as a basic example of how to embed a Silverlight app in a page. You should find it in the project folder.
Silverlight projects are commonly built into a XAP file when you hit "Build" in VS. This file lives in the bin/Release or bin/Debug folder and basically contains your whole application.
Steps to create a silverlight application Hosted in a web site,
Select Silverlight Application Template while adding new project in VS2010
When you click Ok, ensure that Host the Silverlight application in a new web site is Checked.(It will create a new ASP.Net web application to host the Silverlight)
If you haven't checked the Host the Silverlight application in a new web site option, you can add a new ASP.Net Web application project and then go to its properties and select Silverlight Applications option in left pane. Then Click Add, select your Silverlight Application to be hosted and click ok. You are done now.
But If haven't selected the Silverlight Application Template, then you might have created a Silverlight Class Library. It wont generate any xap file. It just gives a dll. So you need to recreate a project as mentioned above.
I believe that in Silverlight whenever you create a project, right at the beginning, it will ask you if you want to create a web app automatically. If you chose yes, something like YOUR_PROJECT_NAME.web will be created, go into that folder, you will find a folder called ClientBin.
The .xap file will be inside that folder.

In my silverlight application I want to open a xaml in a new web browser. how can I do that?
with HTMLPage.Window.Navigate it is just aspx pages - maybe I can convert xaml to aspx?
10x!
a XAML page cannot be shown in a browser window. What Silverlight do actually is showing the Silverlight program within an < object > tag in the aspx (or html) page; nothing more.
In your silverlight project, if you chose to host your project in a new web site, you will see a second project with both a htm and aspx file that hosts that object that links to your xap file.
So basically, you need to create a second Silverlight project that will be hosted in a different aspx page. Then in your main silverlight project your can open that new aspx page in a new web browser window.
I added a Silverlight application to my ASP.NET website. Visual Studio made a new silverlight project and added its xap to the ClientBin folder under the project of my website. So both the projects are under one solution.
My Silverlight app is supposed to read an xml file and I was unable to make it access the file from the client bin folder under the website project. Adding a reference to that project does not work since it says only references to other silverlight applications can be added. Right now its working when the file is under the silverlight project but not when it is under the website project.
how can I make it read the file from website project?
The project structure is
WEBSITE1 (solution)
-WEBSITE1 (project)
-ClientBin
-file0.xml
-silverlightchart.xap
-SilverlightChart
-file1.xml
I can access file1.xml using
XDocument document = XDocument.Load("file1.xml");
I want to access file0.xml but no path works for me, for e.g,
XDocument document = XDocument.Load("~/ClientBin/file0.xml");
and WEBSITE1 is the startup project
You should be able to read a file from the ClientBin folder simply enough without needing to do anything special. At a guess I would say the you have accidentally set the Silverlight application as the startup project. In this scenario you want the website to be the startup project then either have the Silverlight apps test page marked as the start page or to navigate to the silverlight page once the browser has started.
Edit
The problem you have is that the Load method is synchronous but Silverlight does not support synchronous access to web resources. Hence passing a Uri to the Load method will only work if the that Uri can be fulfilled by content in the Xap. Thats why an Xml file in the silverlight project works because it ends up in the Xap.
To fetch Xml from the site you need to do this:-
WebClient client = new WebClient();
client.DownloadStringCompleted += (s, args) =>
{
XDocument document = XDocument.Load(args.result);
SomeFunctionToContinueWithDocumentProcess(document);
}
client.DownloadStringAsync(new Uri("file0.xml", UriKind.Relative);
// code exits here but _document won't be loaded yet
I'm making a WebPart for SharePoint that will instantiate a Silverlight UserControl and feed it some data. My problem is that when I have created my sample-WebPart and just instantiate a Silverlight control, the webpart, when added to a page or displayed in the webpart gallery, instead of rendering blank, renders an error page saying "File Not Found". No clue in the logfiles to what file was not found or why this error is thrown. Here is my code:
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.SilverlightControls;
namespace TestSLWP {
public class CustomWebPart1 : WebPart {
protected override void CreateChildControls() {
Label lblHello = new Label();
lblHello.Text = "Hello";
Controls.Add(lblHello);
Silverlight sl = new Silverlight();
}
}
}
I've added references to System.Web.Extensions and System.Web.Silverlight to the project. They are in the GAC, and the webpart is written and compiled on the same computer that SharePoint resides. If I change the CreateChildControls() to be:
protected override void CreateChildControls() {
Silverlight sl = new Silverlight();
sl.ID = "CustomWebPart1SL";
sl.Source = "/Silverlight/CustomWebPart.xap";
this.Controls.Add(sl);
}
I get the same error. Also if I remove the first slash in sl.Source I get the same error, even though the file is present in a virtual directory in the same application pool as SharePoint. I therefore, and because the error comes with just instantiating the Silverlight object, believe that the file that cannot be found is not my XAP.
What file can't SharePoint find and what can I do about it?
Here's the error message:

Hi I found a complete walk through on how to get Silverlight web parts get running on your application: http://www.vbforums.com/archive/index.php/t-557072.html
As you can see there are added some more things to the web.config beside your assembly registration.
Enabling SilverLight requires a lagre amount of web config modifications. Did you add those?
There could be the problem with your storage folder with silverlight control. You must register path to this storage as safe in web.config (for example find in web.config line with "~/controltemplates").
