Hi,

 I recently installed Visual Studio 2008 Standard Edition and the Visual Studio 2008 Silverlight Tools Add-On. However, I'm having trouble debugging. I can't put a breakpoint anywhere in code ( it becomes an empty red circle and says: "No symbols have been loaded for this document" ). It has been suggested that I go to "Start Options..." by right clicking on the web project and checking the "Silverlight" box under the Debugging section, however I don't have that check box. The only box I have is ASP.NET.

 
Anyone know what the problem is?

Thanks in advance!

 

 You need to add silverlight link to your Web Project. Take a look at this thread:

Hello,

This is a known-issue for VS 2008 standard user. Removing and re-adding Silverlightlink will solve your problem..

Hmmm, removing and then re-adding my Silverlight link doesn't seem to do anything.

Maybe I'm missing a step:

1. Right click on my web project and select "Start Options..." ( noticing under the "Debuggers" section there is only a check box for "ASP.NET" )

2. Select "Silverlight Links" from the options on the left and remove the only Silverlight link I have ( proj.Silverlight.Main with a "Path in Web" as '/' )

3. Re-add the Silverlight link by selecting "Link to an existing Silverlight project in the soluction" and choosing the only one I have in the drop down list ( proj.Silverlight.Main ) keeping the "Destination Folder" as '/' and both of the check boxes under "Link Options" ticked. It asks me if I want to replace the .html test page I already have....I say "Yes".

4. I go back to the "Start Options" menu from the left column....but unfortunately there is no "Silverlight" checkbox under the "Debuggers" section :(

5. I even try doing a full re-compile and setting a break point but get the same error.

Maybe I'm doing something wrong in the process of re-adding the Silverlight link?

Any help would be great! Thanks!

Yup, the check box for "Enable Silverlight Debuggin" is checked. I've tried unchecking it and then re-checking it just to make sure, but no luck there either. :(

The application startup doesn't get hit. We have a test page that is the main .html page set as the startup page to use when debugging. And the web project is also set as the startup project.

It still won't let me put breakpoints anywhere ( saying that debug symbols haven't been created for the application yet ).

Try to delete the ClientBin folder under your Web Project then rebuild your web project. By the way, can you see the .Xap file in that folder?

What is in your main.html page? Could you show the silverlight object tag in your main.html page?

Deleting the ClientBin and rebuilding didn't seem to do the trick either.

Here's the main .html silverlight object definition:

<!-- Runtime errors from Silverlight will be displayed here.
    This will contain debugging information and should be removed or hidden when debugging is completed -->
    <div id='errorLocation' style="font-size: small;color: Gray;"></div>

    <div id="silverlightControlHost">
        <object id="slCtlHostObj" data="data:application/x-silverlight," type="application/x-silverlight-2-b1" width="100%" height="100%">
            <param name="source" value="ClientBin/proj.Silverlight.Main.xap"/>
            <param name="onerror" value="onSilverlightError" />
            <param name="background" value="Transparent" />
            <param name="windowless" value="True" />
           
           
            <a href="http://go.microsoft.com/fwlink/?LinkID=108182" style="text-decoration: none;">

            </a>
        </object>
        <iframe style='visibility:hidden;height:0;width:0;border:0px'></iframe>
    </div>

I don't see anything wrong. Now I have no idea why you can not debug. Usually removing/re-adding silverlight link should fixed it. Is your page working at all (even you can not debug it)? Do you see the silverlight loaded on your page?

Your project build mode is "DEBUG", right?

Hmmm, ok :( Yeah, the silverlight page works correctly. The only thing that doesn't work is the debugging.

If anyone has any information on what might be happening please let me know! Any help would be greatly appreciated! Thank you!

Hehe, yup, it's on DEBUG mode with MIXED PLATFORMS.

 Maybe I'm beating a dead horse here...but anyone have any ideas? I'm up for trying anything to be able to debug at this point :)

Yes. That's a known issue. We have discussed about this issue in this post. http://silverlight.net/forums/p/14211/47204.aspx

 Yes.

• Open your project in VS 2008
  
• Open Solution Explorer
• Right-click on your web project.
  
• Find "Add Silverlight Link" or "Remove Silverlight Link"   << This is very important step. Let me know if you can't find
  
• If you get "Add Silverlight Link" on content menu, please select it.
  
• If you get "Remove Silverlight Link" on content menu, please select it. then, right click again. So, you will get "Add Silverlight link" this time. then, select this option.

Yes, I've tried removing and re-adding the Silverlight link from the right click menu as well as from within the property pages. Neither seems to do the trick.

The weird thing is the right click menu gives me the "Add Silverlight Link" even though it is already linked. If I click on "Add Silverlight Link" and then click "Add" in the popup that follows, I get an error saying: "The project proj.Silverlight.Web already has a Silverlight link to the selected project at destination folder of '/'. " So even though there is a Silverlight link already present, it never gives me the right click menu option of "Remove Silverlight Link". However, I CAN remove it from within the "Property Pages" popup by selecting "Silverlight Links" from the left hand menu and then selecting the project and clicking on "Remove".

Yes.

Can you try to create "new" project?

• Then, go to "Property Pages" and remove "Silverlight links"  (There shouldn't be any error.)
• Right-click "Add Silverlight Link" (There shouldn't be any error too. Let me know if you get the error)
• Clean the solution.
• Re-build the solution.
• Set the breakpoint in Page.xaml.cs
• Run the project with F5.

Yes, that works!

I was then able to get my project debugging correctly. I feel really stupid now, here's what I was doing wrong: When you first startup the project your breakpoints become empty circles for a few seconds before they "re-enable" ( guess I'm used to standard windows applications where that doesn't happen ). I was simply getting frusturated and killing the project as soon as I saw that they became empty circles. After that I focused to much on there not being a "Silverlight" check box under the "Debuggers" section of the property pages without simply trying more breakpoints and seeing if they hit.

Thank you, thank you, thank you! Sorry to take peoples time on this! Much appreciated!

Good. :) I'm glad to hear that your problem is solved. :)
