title: Is there a way to use reportviewer 9 in Visual Studio 2010 and still have rdlc designer support?
body: <p>I've got an annoying problem here. I've recently upgraded to VS 2010. I really like VS-2010 and I want to keep using it. However I ran into a problem. When I tried to open the rdlc files it bitched at me that my RDLC report files were the old version (used the vs2008 rdlc files) and it had to upgrade them to the new version to support the new report designer. After I did this reportviewer 9 was complaining it couldn't use these files, so I had to "upgrade" to reportviewer 10 which I've found is a complete piece of trash. It's so slow in rendering its pretty much useless to me. </p>
  
  <p>I really need a way to continue to use reportviewer 9 and VS 2010 and still have designer support. Can I open rdlc files individually with vs2008? Has anybody been fighting with reportviewer 10 lately?</p>
  
  <p>Alternatively if someone knows a magic fix to make reportviewer 10 render reports as fast as 9 I'd accept that as an answer as well.</p>
