Usefull visual studio extentions
 

my favorite:
Visual Assist
Visual Leak Detector

what yours?

Devart Code Compare
both standalone and VS integrated.

The Visual Studio it's really complete. But I like this:

-Cosmos: to create a simple O.S in C#
-IronPython: to work with Python on VStudio.
-ReSharper: useful to make a better code.
-Telerik components: good design it's always good.
-Reflector plugin: to dissamble while you use VSudio.

I think this plugins are really useful.

me too, i'am using
- ReSharper for C#
- and Visual Assist for C / C++
programming

For Me,
ReSharper but The two annoying things about Resharper are
1. It's High Resource/Memory Usage.
2. it always wants me to use "Var" when declaring variable types and this gets on My Nerves.
Other than the above issues, Resharper is Swiss Army Knife for me.

could you put more info pls?

reflector
vmware

CodeRush is not bad but it is resource hungry. If don't have a fast PC, it can be really annoying.

VisualAssist for VS below 2012,
VMWare,
Intel Parallel Studio

ViEmu, for Vim funs
WinGDB, linux remote debugger

Using mostly Visual Assist X and Atomineer :)

Image Watch

CodeRush and Resharper, CodeRush is really good but needs a lot of memory

Visual Assit X
Cpp check integration

For C# - imo, nothing better then ReSharper & Reflector

Something a little out of the box though -- With PowerSpolit and Nishang PowerShell frameworks being as robust and extensible as they are, this VS extension may be of interest to you.

Visual Assist of course, VTune for optimization, but also Image Watch. It's simply invaluable when working on anything related to image/video processing.

that reminds me what is the latest version of vtunes that supports vs2013?

Visual Assist
Visual Leak Detector

Visual Assist but even that can take up quite a lot of memory resources on a very large project.

ReSharper
my favorite!

Go To Definition is very usefull extention for visual studio

resharper will support c++ too. when its out it will be awesome. EAP build were available afaik. more info here: http://blog.jetbrains.com/dotnet/2013/06/26/resharper-to-support-c/

Truth is, we need some competition for VAX, hope Resharper will be that even if many are compaining that at moment is kind of slow.

Visual Assist
TabsStudio (www.tabsstudio.com) << useful addon
PVS-Studio

this tabsstudio its really good thank you for letting know

CodeMaid is a quite handy extension as well: http://www.codemaid.net/
It adds several useful features related with refactoring, code editing and some other stuff. ;-)

Useful, but I do wish somebody would incorporate AStyle into a VS plugin. It's a really good program for formatting source exactly as you like it and is very configurable.

Yes, that one :). Wonderful, I had no idea it existed, and it let me put all my normal settings in. Perfect.
