Blend + SketchFlow for VS 2012 -- no go-live license

Question

For projects involving .NET 4.5, Microsoft has provided the preview of Blend + SketchFlow for VS 2012.  However, they've made it clear that this is for evaluation only, and contains no go-live.  My understanding of that means that there is no license to create or work on projects intended for the real world. Am I correct in this assumption?

They have also indicated that for .NET 4.5 projects the tool for Blend users to use is Visual Studio 2012.

Being on the design side, and having relatively little experience with VS2012, I'm learning the ropes of it. There are a lot of tools now built into it over VS2010 that Blend has (document outline, property explorers, visual template editing). 

One thing that escapes me though (and I'm aware this isn't really a BLEND question, but thinking there are other blend users out there in a position like myself) is how to edit a style stored in a resource dictionary that isn't accessible by editing the style of a parent object?  For example, I can right click on a combo box and access my style visually that's stored in the resource dictionary.  Right below that in the xaml, I have another style I want to edit, but isn't used anywhere--how do I get THAT style to render in the IDE for design-time editing?

Any tips/hints would be greatly appreciated.
