c# offers a nice way to document your c#-code. But I don´t find any nice viewer. I search something like the java-doc-viewer in eclipse. This viewer allows you to browse in the java-doc just by moving your mouse over eg. a class-name.
Does someone know a good extension for Visual Studio 2010 that contains such a viewer?
I have the “Productivity Power Tools”-Extension installed. But it hasn´t a real doc-viewer either.

And this is the best I can find for VisualStudio:

You try using CR_Documentor, if you don’t mind installing Code Rush (alone for that purpose; you only need the free "DXCore" actually, checkout the project’s homepage for more information).
Note that this tool doesn’t require a prior generation of the documentation using tools like Sandcastle. It works by simply placing your cursor in a API comment block, e.g. that of a method.
Obviously, this has some drawbacks, for example, links to other items (e.g.
<see/>or<seealso>will be rendered as a link, but don’t work as such).This is what it looks like:
I was using it once, way back when it was still maintained by the original author Lutz Roeder, and it did it’s job well. I have not been using it since.
Update: You could also use ReSharper, which provides a "Quick Documentation" feature.
