In my solution I have a MVC project. Then I added a Silverlight project. When I added the Silverlight project, I set to include it in the existing web application (MVC project). 

It added an `.aspx` page that contains the Silverlight component. The problem is that I cannot debug into the Silverlight code when I start the ASP.NET MVC application. I set a breakpoint in the `Application_Startup` function in the Silverlight code, but it never stops there. On the breakpoint I have a tooltip:

> 
> The breakpoint will not currently be hit. No symbols have been loaded for this document
> 
> 
> 

How do I fix this problem?
