Silverlight Resource Tip
If you are building a default template for your custom control , then you would define it in a file called Generic.xaml and include it as a resource. When you do so , make sure that the custom tool and Custom tool namespace entries are cleared .Other wise , the template will not show up
If it looks like below ( note the Custom Tool entry), it does not work
This is how the properties should look for it to work
Note the entry for custom tool is cleared
