good soft,I like it
by gwblue on May 4, 2014 at 4:25 AM
Great integration with VS2013. I have used stylecop from VS2010. It helps keep me inline with a consistent coding guideline but also lets me evaluate other developers code. Using this tool during code reviews helps keep the engineers looking at the code objectively and not personally.

Works like a charm ;-)

Still excellent!

This is awesome with resharper!
by toddlergenx on Apr 1, 2014 at 2:19 PM
Wouldn't code without it!
by TheMouthOfACow on Mar 24, 2014 at 3:19 PM
Excellent tool, I use it on all projects I am involved in. I really appreciate the quick updates to support new ReSharper releases!
by objo on Mar 11, 2014 at 11:22 AM
One of the tools which is always installed besides after resharper when setting up a new development machine.. Awesome tool.. keeps the whole code in same style.. no matter if the code is written in India or US.. :) Amazing.. thanks a lot for this awesome tool..

Best Tool since ReSharper :-)
by Jeg_Ispin on Jan 10, 2014 at 9:39 AM
This is a great tool! I use it everyday.
by koistya on Nov 27, 2013 at 5:49 PM
Incredibly helpful for the development work that I do.

8.0.2000? VS2013?
by MS_DaveH on Oct 17, 2013 at 11:09 PM
It just works.
by ShaunLuttin on Oct 16, 2013 at 8:48 AM
When is support for 8.0.1000 expected? Thanks!
by johankr on Sep 17, 2013 at 7:56 AM
Great tool, fast support for R#8, good job!
by nhx on Jul 26, 2013 at 1:16 PM
Awesome to create common rules through all development team.
by solasoft on May 26, 2013 at 10:34 PM
I have been forced to use StyleCop in a couple of companies and I'm sorry to say it is not a tool I would recommend to a developer with good standards It integrates well with resharper and I find some of its rules useful. There are however many rules that feel pretty trivial: not allowed to leave two blank lines, comments have to start with a space (not compliant with the default VS automatic comment button) etc You can still disable those warnings and leave the formatting to the Resharper cleanup tool (ctrl + E,C). so that would be ok However my main complain are rules that I simply believe your code worse like: - fields variables don't prefix with _ so they are confused with parameters and it forces you to use "this." keyword all over - Dummy comments not giving any information This rules makes the code more verbose and MORE difficult to read, defeating the initial purpose of the application. Furthermore while resharper does a great job finding bugs (e.g. unused variables) stylecop not only will not help you there but it may actually hinder you.
by blackForest on Dec 7, 2015 at 9:48 AM
As I could check it's fully compatible with ReSharper 8.2
by JohanTG on Jun 24, 2015 at 7:38 AM
StyleCop is an Awesome tool for developers to know what to follow and what not to ...... it helps my team a lot and brings code consistency in our projects.
by susantasahu01 on Jun 13, 2015 at 6:17 AM
StyleCop and ReSharper are a great combination. However, I can't seem to install StyleCop with a clean install of the lastest build of ReSharper. I'm going to assume however, this will be updated to work with the latest and greatest at the time of Visual Studio 2015's release as this also doesn't work with that either.
by jamescroft on May 24, 2015 at 8:25 AM
Uninstall leaves menus in VS changed, hidden options, Visual Studio errors; generally a poor uninstall experience. It would be nice to have more control over what StyleCop is actually doing, as the default install is very difficult to integrate into an existing codebase that doesn't follow all the rules. Possibly an installation option that is 'change nothing, let me decide what to turn on' would go a long way to helping this user experience be better.
by naviwhack on Feb 17, 2015 at 1:43 PM
Stylecop is excellent, but I need to get an earlier compatible with R# 8.0 But the link for previous versions is currently broken. Please investigate and correct it. Thanks. I'm trying to download this version:
by derekadk on Oct 21, 2014 at 12:55 AM
Some of the checks are useful, but some others I find bothersome. If I CHOOSE to change my environment to differ from the StyleCop 'conventions' I don't want StyleCop to tell me that my way of writing code is considered 'bad conduct' some examples: 1. I use _variable to assign my private fields -> this avoids the typos when working with properties. Stylecop practically forces me to change my way away from the settings I set in Resharper just because YOU think it's bad. 2. I place my fields and properties in the same region (one region per property and one region per method group). StyleCop forces me to place all my fields before my constructors. This leads to inefficient code. If I remove a property, all I have to do is delete the region and poof my field disssapears also. I don't have to remember to remove the field. I have otherthings to do than constantly check my code for 'missed items' YOU'RE AN ADDON TO RESHARPER AND NOT THE OTHER WAY!!!!!!!!!!!!!!!!!!!! If Resharper rules changed, it's because the USER changed them and it's not up to you to tell the user that his way of working is wrong, it's just different. StyleCop should be about consistency and not dictatorship.

Brilliant for defining code quality standards and ensuring your whole team sticks to it.
by AliRuss on Aug 18, 2014 at 10:32 AM
Stylecop is one of the tools every developer should know and use.
by BLJ on Apr 1, 2014 at 5:50 PM
Best tool ever. Every day use, of course. We use it in our company and we all love it.
by the_Crispy on Dec 14, 2013 at 7:10 PM
Sometimes crash (freeze) VS2010 and VS2012 with R#
by build_your_web on Sep 5, 2013 at 10:01 AM
Anyone else getting this problem? I think its fixed in the latest releases.

I use it on all my projects development !
by GillesTourreau on Apr 23, 2013 at 6:08 PM
Excellent and very handy tool. Must have.
by Destroer on Mar 11, 2013 at 6:08 PM
Thank you !! Great tool !!
by niko78 on Mar 1, 2013 at 12:53 PM
Not using it, is not an option!
by gsscoder on Feb 19, 2013 at 2:40 PM
Nice job with JetBrain, but still need a lot of resource for large file.
by Lez4dev on Jan 19, 2013 at 3:30 PM
Great release, good job! (R#7.1)
by paulkohler on Nov 15, 2012 at 12:26 AM
I love it.
by cristianmad on Nov 14, 2012 at 12:25 PM
Excellent work! It should be used by every team that wants to ensure that a common programming form is used all across their code. 100% recommended! It should check other languageslike: JavaScript, T-SQL, HTML, CSS. I know there are other tools but this one is really easy to learn and use and a common place to configure all code rules could be the best.
by ffernandez on Nov 14, 2012 at 12:12 PM
Helps distributed teams write consistent code. Many thanks.
by LouO on Nov 7, 2012 at 5:34 PM
Crashes when trying to use on large projects. Unable to use to scan a full project. Added my details to the bug report and going to revert to prior version to see if it is fixed.
by AJH16 on Oct 16, 2012 at 8:55 PM
Great extension, makes writing consistent code so much easier. I will try to get my company to adopt this ASAP.
by mareklinka on Sep 30, 2012 at 9:28 AM
This is a must have esp with R#7 and many thanks for VS2012 effort. Did notice I have to reset my styles in resharper to get 4.7 working tho, but that was just a click on the reinstall.
by dougthompsonwdr on Aug 29, 2012 at 6:34 PM
A great way to get a large team to write code; helps avoid stylistic differences.
by stevecooperor on Jul 5, 2012 at 1:34 PM
Thanks , I love this and special thank for 2012 RC compat
by ashwini47 on Jun 8, 2012 at 12:06 PM
The support for this project over codeplex is top notch. Kudos to Microsoft/andyr for not simply open sourcing their code by throwing it to the wolves but ensuring that the project stays alive. Keeping up with EAP's and RC's is a major bonus!
by felickz on Jun 6, 2012 at 4:02 PM
Thanks for the hard work Andy. This version works great! Running on VS 11.
by vincentw56 on May 30, 2012 at 7:55 PM
Excellent tool. Thank you Andrew for your hard work. I very much appreciate the integration with Resharper 7 EAP with
by TATWORTH on May 30, 2012 at 12:23 PM
After clean installation of this release it didn't change the VS 2010 templates for web project (It does on class libraries). And also the StyleCop commands didn't add to project context menu of the VS 11 Beta. (Note: R# 7 beta was installed on VS 11 Beta)
by amirkarimi on May 27, 2012 at 1:02 PM
StyleCop is the best tool ever! Andy is super dedicated and responsive.
by StealthMonkey on May 16, 2012 at 10:05 PM
Fantastic tool for maintaining consistent code formatting in shared projects. It helps I agree with alomost all the default rules, with the noticable exception of the "spaces not tabs"! If you share code between developers consistent style is a must, this tool makes that automatic.
by stensones on May 1, 2012 at 12:48 PM
Thanks for keeping this tool alive though all of the changes with R#. This tool is essential part of our development. Just installed v4.7.17 and everything is working flawlessly.
by kobelsem on Mar 23, 2012 at 1:52 AM
Localization is working great !!
by pbaelen on Mar 21, 2012 at 3:50 PM
Great tool! Thanks for it. Makes code easier to read .
by DerSkuggan on Mar 19, 2012 at 8:17 AM
Besides Resharper is one of the most useful tools for C# developers. A must for any development team that follows best practices and coding standards.
by alexpop on Feb 24, 2012 at 9:38 AM
Just about as good as it gets. Superb release with all the stability you can get, thanks to continuous dedication to unit testing.
by soygul on Feb 23, 2012 at 12:05 PM
Since 6.1.1 is officially out, it'd be great to have a corresponding release of 4.7 to work with it without the installer warning.
by ajthomas on Feb 21, 2012 at 9:14 PM
One of the most useful tools ever! A must have!
by andrescor22 on Feb 15, 2012 at 3:51 PM
Looks like this version is working fine.
by thoughtcriminal on Feb 7, 2012 at 12:48 PM
Great work on constantly improving the release. Would be perfect once the R# dependency on a stable release of theirs established as well, but this is best that can be done.
by ercenk on Feb 2, 2012 at 5:23 PM
Spot on good work. And for those complaining about the expiry of R# 6.1.38 just go and download the latest EAP from I'm using without any issues
by cjrodwell on Feb 1, 2012 at 8:48 AM
I have been waiting for the vs11 support, by the way i updated the Attrice check in policy to use this version if anyone want it.
by jmzamudio on Jan 9, 2012 at 6:20 PM
StyleCop make VS2010 to Crash!! I don't know how was old version of this app but I installed StyleCop and each time I run the SyleCop the Visual Studio 2010 crashes. I guess that's not such good app after all.
by Gil_Epshtain on Aug 7, 2013 at 3:10 PM
Does not uninstall properly, and intentionally hides itself from Visual Studio's extension list.
