Resharper 4.0 in now in beta previous: Easy extensibility: xUnit integration for DSL next: Testing DSL Syntax with Interaction Based Testing Just got the email about it. ReSharper 4.0 moved to a beta status. You can find the details here. Personally, I have been using a fairly old build, with relatively few problems. Comments 05/23/2008 01:40 AM by Eric Hauser You should definately get the latest. Starting with the one they labeled release candidate I have noticed a significant speed increase over the other nightly drops. 05/23/2008 06:24 AM by Petar Repac My team is looking for ways of increasing productivity. Could you or others give some estimation of productivity gain when using Resharper compared to using plain VS2008 ? Thanks in advance. Petar 05/23/2008 07:32 AM by Ayende Rahien 351.54% productivity increase. 05/23/2008 08:52 AM by Ilya Ryzhenkov They counted it here: http://blog.noop.se/2008/05/22/ReSharper+40+Beta+Is+Out.aspx So for that case, the number is something like 326% However, if we add live templates, create from usage, extract method refactoring, the number could be something like 400% or more. 05/23/2008 09:29 AM by Petar Repac 351.54% productivity increase. So you went to sleep and in the morning R# finished the project ? :)) 05/23/2008 11:56 AM by Petar Repac Joking aside, how did you get the 351.54 % ? 05/23/2008 12:55 PM by t800t8 I guess Oren calculated from the number of characters you need to type. 05/23/2008 01:18 PM by Alex Simkin VB.NET 9.0 programmers can ignore this announcement. 05/23/2008 01:29 PM by Petar Repac t800t8, My guess would be that R# keeps this statistic and shows it on demand. 05/23/2008 01:50 PM by Louis Or he could have pulled an absurdly precise number out of thin air as a zen way of highlighting out the impossibility of deriving such a distilled quantification that has any meaning. 05/23/2008 01:56 PM by Meowth I don't believe in such precise numbers. I hope this is not more than funny - to put such qualified numbers. BTW, how do you think how much MS can pay and will to Re# team to incorporate their work into VS.vNEXT? =) 05/23/2008 02:02 PM by Petar Repac Luis, Yes, I also was under impression that Oren was a little sarcastic. Anyway I wasn't looking for some precise number, but for general feedback in productivity gain from developers that use R#. Regards, Petar 05/23/2008 05:08 PM by paul where is the jetbrains ide 05/24/2008 02:25 AM by Marcin Seredynski Petar, remember that 83.27% of the statistics are made up on the spot ;). Although R# is a great tool and saves a lot of typing, majority of the work happens inside the developer's head. Productivity boost comes from a responsive environment that does not get into your way - R# is pretty good at making a good code editor out of VS2008. Ideally, I would like to have R# for Notepad++, to get faster load times :) 05/25/2008 03:51 AM by Lucas Goodwin I've seen atleast 3 times the increase in productivity in terms of refactoring operations. Move and Rename are unbelievably time saving. The other gains I've experienced have been more due to how well R# supports the TDD process via it's tooling. Auto-creation of methods, classes, etc. Saves a good deal of time and allows me to focus more on the design aspect of TDD. 05/25/2008 10:29 AM by Ulu Alex: don't they have a separate VB edition? By the way, has anybody worked with DevExpress' CodeRush? How does it compare to R#? 05/25/2008 05:53 PM by Petar Repac Ulu, As I understand it CodeRush is code generation tool so it shouldn't be compared with Resharper. DevExpress has Refactor! Pro and it is more suited to be compared with Resharper. 05/26/2008 11:50 AM by Mats Helander http://martinfowler.com/bliki/CannotMeasureProductivity.html I find that the productivity raiser in tools like resharper has a lot to do with how they help you deal with mistakes (think: rename). This means that a coder who makes a lot of mistakes may see a greater productivity increase. In other words, your devs may not become that much more productive with Re#. If you hired me, otoh, you could probably see something like a 5000% productivity improvement. Of course, I would charge a premium rate for such amazing productivity increasing potential! ;-) /Mats 05/28/2008 07:30 AM by Ulu So, anybody tried Refactor! Pro? Their list of refactorings looks pretty impressive.. Comments have been closed on this topic.
