From Java and Eclipse I'm used to @inheritDoc that allows to use the same documentation as in the base class/method.
How can I accomplish something similar in C# and Visual Studio 2010?
It doesn't exist in vanilla VS. Your best bet is ghostdoc or similar. This is available in the Extension Manager, or here
Even this question is a few years old and it was specifically for Visual Studio 2010. For all those that land here by Google, I would like to add an answer that I found and that holds true for Visual Studio 2015 in combination with Sandcastle Help File Builder (SHFB):
/// <inheritdoc/>
can be used to inherit the docs from a base class or an interface.
Here a link to the Sandcastle Help File Builder (SHFB) documentation: Using the <inheritdoc /> Tag
ReSharper not only provides shortcut keys to copy base class comments, but it actually includes <inheritdoc> comments in its custom intellisense the way you want. This only works if your whole team is using ReSharper of course.
Usage of <inheritdoc> is explained well here
Resharper provides shortcuts to copy the XML documentation from base classes.
My addin, AtomineerUtils will duplicate documentation from overrides of base class and interface methods/properties, from overloads in the same class, and for parameters it will also look for same-named parameters used elsewhere in the same class.
You may also be able to use extension XML commands like <inheritdoc> or <include> if you want to duplicate the text in external documentation (Sandcastle, Doxygen, etc), but I'm not aware of any way of "dynamically" inheriting documentation for "internal" use (intellisense etc)
I ended up creating a tool to add support for replacing the <inheritdoc/> tag by post-processing the XML documentation files. Available at www.inheritdoc.io (free version available).
NDoc3 is based on NDoc, and is a code documentation generation tool for .NET developers. The goal is to make a fast, extensible, multi-platform .NET documentation tool which supports all of the .NET languages specifications including but not only, C#
