Thank You!

No more LESS support in the latest version. But "LESS" is there on the product page, there's even a LESS-settings tab in the options. Thanks for ruining our work process.

This extension is #1 result in Google for "Visual Studio LESS".

PS. the new "ASP.NET and Web Tools 2012.2" only highlights LESS code, but does not compile it!! So your answer does not help!!

Amazing extension!

Nice tools, but unfortunately Typescript is left out of the recent update. So a lot of the functionality I used is not available anymore.

Unfortunately, VS Express doesn't support 3rd party extension. It's not a limitation of Web Essentials

Dropping support for TypeScript (without plastering that "little" detail all over the download page) has just cost me 4 wasted hours and sent me full circle back to the old Web Essentials.

1. Installed Web essential update
- lost TypeScript support

2. Installed separate TypeScript add-in from MS
- Does not build existing TypeScript files in project

3. Researched how to modify project to get it to build TypeScript files
- Still does not build existing TypeScript files in project

4. Created a new project minimal testbed to test TypeScript compiling
- ts files are added, with TypeScriptCompile option, but do not generate .js files at all. Tools | Options etc have no effect

5. Researched this new problem
- Gave up in disgust

6. Uninstalled TypeScript & latest Web Essentials

7. Installed old Web Essentials
- Luckily this was still in my download folder

8. Have now lost color-coding, intellisense and all those other features that made Web Essentials useful.
- Decide to write grumpy review :(

I have never had so much grief from one update. In future I will Google for problems with the updates before even thinking about pressing upgrade!

WebEssentials 2012 is a stellar extension. Being able to collapse JavaScript between {curly brackets} is very useful.

  • Markdown preview not showing anymore
    1 Posts | Last post November 11, 2015
    • When editing a markdown file, I used to have a split screen that shows the source and then the "generated" file in preview mode. However, ever since I closed and reopen the solution, I don't see the preview anymore. Is there a command to get it back?
  • Can't get Markdown to work

    • Which MarkDown dialect is used by WebEssentials?
    • While trying to install it tells me:
      "The extension 'Web Essentials 2012' requires a version of the .NET Framework that is not installed."
      Which one is required?

  • Error when using Re-Minify all CSS/JS files
    1 Posts | Last post March 17, 2015
    • I get this error:
      Microsoft Visual Studio
      Not implemented (Exception from HRESULT: 0x80004001 (E_NOTIMPL))
  • Permission Denied
    1 Posts | Last post March 12, 2015
    • I work in an environment where we have very limited permissions on our computer. I installed Web Essentials 2012 and created a blank .less file. The preview window is showing
      Compile Error.  See error list for details
      I pulled up the error list and it's showing
      LESS: Permission denied
      I can't find the error in any log or the event viewer so I don't know which account needs permissions to what folder. I tried giving everyone all permissions to the folder that contains the .less file just to see if that was where the error is, but that didn't do it. Does anybody know which folder it writes to? The temp asp.net folder maybe? Do you also know what account needs permissions? I don't have rights to modify the temp asp folder, so I'd have to put in a request with my IT department, so I can't really just play around and figure it out via trial and error.
      I've spent a few days trying to find an answer to this, but I'm not getting anywhere. If someone could point me in the right direction, that would be awesome.

  • SASS Compile Error Link
    1 Posts | Last post October 14, 2014
    • When you compile a not valid SASS files a Link Error is generated.
      This link is not connected to a running Web server.
      How can I customize this link.
      e.g. http://localhost:80/error.aspx
      Something went wrong reaching:
  • Recompile all less files doesn't work
    3 Posts | Last post October 11, 2014
    • Recompile all less files worked just fine, but when I've checkout fresh version into another folder it stop working (including recompile after build).
      If I open less file, change it and save (css is created) then this file works automatically since then just fine.
      Should I open each time I create a new repository all less files, or there is another way?
    • I have comitted only .less files, once I add corresponded .css, Web Essentials start works with it as expected.
    • The only way, find out for now is to commit .css files too. Though all my .css files are autogenerated and therefore it is a pitty, that I should commit .css along with .less and checkin .css on change of less too.
  • Minify CSS
    1 Posts | Last post September 30, 2014
    • On CSS minify, should there be an option to remove empty selectors?
