I'm trying to use the current SL beta version of the samples #1 and #2 with the SL 2.0 RTM runtime and am getting the following error message "Failed to load the application. It was built with an obsolete version of silverlight".

How can I workaround this problem when using the SL 2.0 RTM bits.

This occured when i was updating from silverlight 2 to silverlight 3. i have tried re installing and updating but nothing worked. thanks to the error none of the silverlight project shows any output. every silverlight testpage is blank. Would be happy to welcome any help regarding this issue.
