Oleg Tkachenko has created a visual studio's plugin for XSLT. You can read all about it and get to his download from his blog: http://www.tkachenko.com/blog/archives/000703.html
Note: it only works with Visual Studio Code Name "Orcas" Beta 1, and you MUST have the SDK installed.
I've downloaded all of the above and am excited about future builds of this plugin. Currently it has the ability to complie XSLT into DLLs. I'm not as interested in that as I am some of the other features to come, but we do have a few projects where I think it may come in handy.
Current list of planned and already implemented IronXSLT features includes:
- XSLT Library Project (Visual Studio project type for compiling XSLT into DLL)
- XSLT Refactorings
- Multiple XSLT engines
- XSLT Profiler
- Extensive library of XSLT code snippets
- XPath Intellisense
- Visual XSLT builder
- XSLT2XLinq and XLinq2XSLT converters
