Windows Phone 7 Download Versions

For windows phone开发者_如何学C addon, do I have to install the express tools download? There isn't any add-on for users who already have Visual Studio RTM? I can't find that anywhere... I don't want to have to install express tools, there's probably an option, but curious if anyone has found that alternative download anywhere.

Thanks,

Brian

Yeah, I was miffed by that too. Don't worry, Express and VS2010 sit side-by-side just fine and if you just use 2010 normally everything works. Just install the tools and trust that everything will be okay. :)
