report server rdl files in visual studio 2008

hacked my way through this mostly by accident; if you rename a .rdl file to .rdlc, then you can open the file in visual studio 2008 and use the same GUI for report file edits that you have in 2005. you don’t get the data and preview tabs, so you need to make data source edits manually in notepad, but if you find yourself with only vs 2008 and need to make .rdl edits, this is a good way to get some GUI help--
