Most usefull extension. Thanks.

I just want to report that latest WE 2012 update to version 2.5.1 does not recognize .less and type script files. I have been tried to uninstall WE and delete settings file then install hadn't fixed anything. Reset whole visual studio settings hadn't too.

Anyone experienced same problem ? How can i fix this problem ? :((

Update: Now i understand that those features currently removed at 2.5 version : (((

We just released the ASP.NET and Web Tools 2012.2 which restores and improves both LESS and CoffeeScript. Get it here: http://go.microsoft.com/fwlink/?LinkId=282650

V2.4.5 supports .coffee file, but doesn't support .less file, v2.5 doesn't support both. why?

Because both LESS and CoffeeScript will be rolled into an official release going out tomorrow morning.

Very useful addition to Visual Studio. Works well in combination with TypeScript. Thanks Mads.

Code manipulations in the TypeScript editor make this extension to hang the VS 2012. Had to uninstall it. Piece of shit.

Fantastic tooling improvements for web developers. Quickly becoming my most cherished extension for VS 2012. Thanks for your hard work!

by Adamlay12233 | February 08 2013

This greatly increases efficiency, and saves time. All these features are combined and integrated really well with Visual Studio, and I've never had any issues with it.
Many thanks for this extension!

Excellent

by drobertson | January 28 2013

Love it, very useful stuff. It fits right into the web work I am doing and is a great help. Would have given you 5 stars, but the incessant updates are killing me. I can't believe I am actually asking for this, but please don't update so often. It seems like every few days Visual Studio is nagging me about another update.

Please don't stop doing the improvements, they are great, but please push them out less frequently. I often just barely notice any difference but I have to reset my system when I do the update. It really kills my flow and when I realize the update didn't have anything useful for me it is frustrating.

I give this an Almost Perfect with a few reservations.

I like Web Essentials 2012 a lot in terms of functionality. However the updates have been so frequent recently that it's getting annoying. It's not that I don't appreciate the effort to fix issues timely but the update notification of VS is so intrusive that I feel obliged to do it right away. So suddenly I find myself installing updates and restarting VS, far distanced from the actual work I was about to do. All for a bugfix I don't experience and a feature I won't use. Please go back to releasing major updates only.

Incredibly useful. This extension is worth getting even if you just want it for LESS editing and nothing else. It might be nice if in the LESS editor, the CSS panel scrolled with the LESS panel, or if it had a search bar.

@Kommundsen You can change the location of the menu item by going into Tools > Customize > Commands, select Build from the "Menu bar" dropdown, select Web Essentials and Move Down (or do whatever else you want to it).

by LEllingsen | January 18 2013

by Kommundsen | January 17 2013

Very nice extension with a lot of good features. I would give this five stars if not for the extremly annoying location of the Web Essentials item in the BUILD menu. I would prefer it to be located further down or as a separate menu.

  • @importing several files fails (thread bombs)
    2 Posts | Last Post Mon 11:26 PM
    • I have a couple of .less files that do no more than facilitate the inclusion of smaller less files -- such as a responsive grid LESS file that sets up media queries and then imports each break, in a total of 6 @import calls (one for grid setup, one for design, for Desktop | Mobile | Tablet). 
      
      When I try to save these files I notice a cscript.exe thread getting up to about 2GB of RAM and then breaking. Is there anyway I can debug this extension to give a better understanding of where this breaks? I get an empty error that simply states 'LESS: '
    • I'm a dummy. The issue I was having was from not using @import-once. I believe @import-once is removed in the latest version of LESS so that's probably why I decided to remove them from my code.
  • @import of files outside current project fails with 404
    12 Posts | Last Post Mon 10:32 PM
    • Hi!
      
      Just upgraded from 2.5.1 to 2.6, and all our cross-project imports stopped working. Like this:
      
      @import "../../../../Themes/MiP.Theme/Styles/mip-mixins.less";
      
      This worked before but now gives the following compiler error:
      LESS: Couldn't load themes/MiP.Theme/Styles/mip-mixins.less (404)
      
      Can you fix this please? :) Or tell us what we're doing wrong. Or provide some kind of workaround. We are not very keen on duplicating all our less files... :)
      
    • Has this been addressed, or is there a workaround?
    • Same problem here.
    • The interesting thing is that LESS is supposed to be handled by Web Tools now since 2.5. Reverting back to the 2.5.1 download from http://vswebessentials.com/changelog fixed my problem. I imagine both Web Tools and Web Essentials have some conflicting dependency for path resolution. 
    • Reverted to 2.5.1 also and all seems well... for now.  Just wish I knew if this is a bug in 2.6 or an intentional change.
    • I am seeing this issue in 2.6 inside of the same project - rolling back to 2.5.1 has not resolved the issue.  Think there may be a remnant lurking somewhere after the uninstall.
    • 3 cycles of uninstall and reinstall later - 2.5.1 now functioning as expected.
    • See this thread for the description of the issue and for a possible workaround: http://forums.asp.net/p/1900852/5371528.aspx/1?p=True&t=635022256782196589
    • Alternatively you can just downgrade the less compiler from v1.3.3 to v1.3.1 which fixes the issue. See here:
      
      http://stackoverflow.com/questions/15691713/less-compiler-and-relative-import-references-not-working-in-web-essentials-2012
    • The "Replace with original 1.3.0" workaround here http://forums.asp.net/p/1900852/5371528.aspx/1?ASP+NET+and+Web+Tools+2012+2+bug+in+resolving+imports+in+LESS+files+workaround+included worked for me.
      
      It looks like the problem is really with Web Tools. I imagine that Web Tools or Web Essentials or both fiddles with the scripts in that directory so reveting to 2.5 reverts the 1.3.3 script to 1.3.0
    • This bug remains in Web Essentials 2.7 as the LESS version is still 1.3.3 and has not been reverted (though the script file name is less-1.3.0.js).
    • Reverting to v1.3.0 in Web Essentials 2.7 doesn't work for me. Instead, it just keeps creating threads that go to compile the LESS but just consume memory.
  • JSDoc and IntelliSense
    2 Posts | Last Post Sun 4:09 PM
    • Is there some magic setting to get JSDoc comments to be parsed for IntelliSense?  I can't seem to get this working in 1.7.  I have a simple test file with the following:
      
      /**
       * Does something.
       * 
       * @param {string} myParam
       */
      function doSomething(myParam) {
      
      }
      
      Inside the function, myParam seems to have no type information.  Outside, inline documentation just spits out the whole unformatted comment block for doSomething.  Anyone have any ideas how to get this to work?  Thanks!
    • I am having the exact same problem.  JSDOC does *NOT* work as described.  Am I missing something?  I am using the exact same format as dornif:
      
      /**
       * Does something.
       * 
       * @param {string} myParam
       */
      function doSomething(myParam) {
      
      }
      
      But when attempting to use 'doSomething', Intellisense just dumps out the entire comment block (/* ... */) above the function instead of providing the intellisense I expect for each parameter.
  • Compile Jade to Html
    1 Posts | Last Post May 11, 2013
    • Jade is a really nice alternative to typing Html manually. The best Jade engine is in node, but to get to use it for non-node apps aswell using it as a pre-processor would be a nice alternative. WebStorm already does this http://stackoverflow.com/questions/15492624/auto-compile-jade-in-webstorm-on-windows 
  • SCSS/SASS support?
    2 Posts | Last Post May 06, 2013
    • Hello , 
      
      Do you plan on bringing a SCSS/SASS support any time soon ? there is another plugin for that , but it doesn't feel as polished as yours and it brings a ton of other features that i don't really need.
      
      Thanks!
    • I would like to echo the sentiments of Aviatrix. I use the "other" plug-in and it doesn't feel as polished as this (and I pay for it). I don't like LESS as much as SCSS (a.k.a. SASS) and that other plug-in is the only one of it's kind to work with visual studio.
  • css files not showing nested under less file.
    1 Posts | Last Post April 28, 2013
    • I have WE 2.6 installed on my work and home PC's, both with VS 2012.2. The css files show linked under the less file on my home PC, but not on my work PC. Both MVC 4.0 apps. Is there a setting I'm missing?
  • Rename page codebehind bug
    2 Posts | Last Post April 28, 2013
    • I have noticed that when I rename an aspx file, the code behind drops the .aspx part and visual studio does not nest the file. Through trial and error I managed to find out that it is Web Essentials 2012 that is causing the issue and with the Plugin disabled it doesn't occur.
    • I can confirm the bug and it's REALLY annoying one :(
  • CSS bundle crash VS2012
    1 Posts | Last Post April 25, 2013
    • Hi,
      
      Making a CSS bundle crashes VS2012 if one of the CSS files do NOT belong to the project.  On a whim, I added the CSS to the project and the error no longer occurred.

  • Build TS on save options crashes web essentials
    3 Posts | Last Post April 16, 2013
    • Hi,
      
      with build typescript on save checked, whenever I now build my project the output from web essentials (ver 2.6 vs2012) contains the following exceptions ;

      Any ideas, I've uninstalled and reinstalled without any success.
      
      Thanks,
    • sorry that should have been 'with compile on build' switched on, this is an mvc 4 application.
    • This seems to be related to out web project, which contains the typescript files, being contained in a solution folder. 
      
      remove it from the solution folder and place at the root of the solution, and it works fine.
      
      
  • Version 2.6 crashes VS2012
    1 Posts | Last Post April 16, 2013
    • Hi,
      
      we've just started using Web Essentials with VS2012 for a new project and thus also started building our CSS from the ground up using LESS.
      
      Unfortunately, we've then been scratching our heads as to why rebuilding our solution didn't also recompile all the LESS files even though exactly that was configured in the LESS options page.
      
      I then threw Reflector and another instance of VS2012 at it and found out that our web app being in a solution folder instead of the root of the solution was the culprit - could you perhaps add recursing into solution folders when looking for projects to compile?
      
      Also, while doing that I found that VS crashes with a "file not found" exception at LessProjectCompiler.MinifyFile when compiling the LESS files during building when the associated minified file is missing and minification is activated. I assume if the file doesn't exist it should just be created... :)
      
      (The reason for that was that we didn't want to check the generated files into our Subversion repository so after a fresh checkout those files will always be missing, and having to touch each of them once to have the minified files generated is iffy...)
      
      Hope this helps.
      
      Kind regards
