A few weeks ago, I mentioned the Reference Assistant extension for Visual Studio in my blog. I've been working closely with Darren Stokes to produce a Visual Studio 2010 version. Darren was quickly able to put together a VS 2010 version of his product and has it packaged up as a VSIX file. That means you can now go to the Extension Manager UI in VS 2010 Beta 1 and download Reference Assistant.
You can also get it directly from the VS Gallery from here but I'd suggest finding and downloading it from the Extension Manager instead :)
We have a few more VSIP partners who are getting ready to also ship their extensions online so keep an eye out for that.
