Getting Xaml parse exception (AG_E_UNKNOWN_ERROR [Line: 97 Position: 84]) after upgrading

[Hector]

I upgraded to the latest release of Telerik Rad Controls for Silverlight and I am now getting this error.  Line 97 right in the middle of a MenuItem .  It seems that the Telerik.Windows.Controls.Navigation namespace is causing the error because I was getting a similiar error with the RadWindow and they both are in the same namespace.  Is there something wrong with my XML code?

I figured it out.  In an effort to thin out the XAP file because it was currently at 4.2MB, and it was taking a while to download whne initializing, I was removing unused references.  One of the dlls I removed was Telerik.Windows.Themes.Office_Silver.dll and this is what was causing the error.  As soon as I added it back on, it was working fine.

Are there other things I can do to make the XAP smaller?

Hello Hector,

There are several ways to reduce the XAP size. Here are some of them:

1. Don't include images in the XAP, download them at runtime
2. Don't reference any dlls that you don't specifically need
3. Use application library caching. More info you can find here:

Hope this is helpful. If you have more questions please let me know.
