Has anyone seen this error before? "The root type was not expected. The following type was expected: "Application'." I've refactored some user controls into their own project/assembly (Created the project as "Silverlight Class Library") and when I open one of the .xaml files in Blend it throws that error and won't show anything in design. Have found one other person post this a year ago on the Silverlight forums with no answer. I'm sure I've done this before without error. Any ideas? cheers, Stephen ________________________________ Support procedure: https://www.codify.com/lists/support List address: [email protected]<mailto:[email protected]> Subscribe: [email protected]<mailto:[email protected]> Unsubscribe: [email protected]<mailto:[email protected]> List FAQ: http://www.codify.com/lists/ozsilverlight Other lists you might want to join: http://www.codify.com/lists -- net noobie(tm) ========================= What is the 'Clean Feed'?
