Silverlight Plug-in Error Messages


This topic lists the error messages that come from the native code implementation of the Silverlight plug-in, and the native code level of the object tree and the XAML parser. The error messages are mainly relevant if you use the JavaScript API technique for error handling (OnError) or for general script-level debugging during development.


Note   Handling errors for the JavaScript API is described in the topic Error Handling.


The error messages might not be relevant to managed user code exception handling with the UnhandledException event. However, in many cases, native errors can occur when you make managed calls to members that use functionality in the core. The native errors might be useful debugging clues during the development phase to determine what aspect of the managed call is not working as expected.


The following table lists the error codes and corresponding error messages. The error messages are displayed only when you have the Silverlight developer runtime installed. For more information, see Silverlight Tools. The end-user runtime provides error codes only, but you can use the following table to look up the corresponding error message.


In many cases, the error message will provide sufficient information for you to diagnose and resolve the error. However, some errors are rare and do not provide an explanatory error message. Additionally, some errors can occur in a wide variety of situations, or due to unforeseen conditions. This makes it difficult to provide general-purpose troubleshooting documentation for plug-in errors.


If you encounter an error that you cannot resolve using the information in the following table, you can find additional help on the Silverlight forums by searching for the error code. If you do not find an existing post that describes your situation, create a new post that includes the error code and describes your scenario. These forums are regularly monitored by the Silverlight product team and developer community, and provide the best way to troubleshoot specific error conditions.
