Just updated to Update 3 along with WE. Now my solution is unusable when debugging. This is my only extension. If I uninstall Web Essentials, the freezing stops.

Can you please be more specific? What are you debugging - C#, JS or...? Can you please upload a repro project if possible?

Barryrowe commented 10 years ago

I am seeing the same thing. The project I'm running is an MVC 4 project, with C# settings, but is mostly JS interacting with a few controllers. I can't upload the project as it's an internal company application, but can answer any questions regarding other project settings.

This only occurs while running/debugging the application. VS runs smoothly if the application is not running.

I have 4 fairly small SASS files (.scss)

I have BrowserLink disabled.

Ditto - I can't upload but can answer any questions. Browserlink is disabled, I have a few LESS files. Seems like it freezes up on a consistent interval.

I also just noticed that even with the extension disabled, I get the same behavior, but with it uninstalled, it's fixed. This is confirmed multiple times after restarting VS.

Me too. Visual Studio is unusable when debugging. I have to wait 2-5 seconds between every key press. I'm running latest WE nightly. If I disable WE, debugging is fine again.

MVC 5 C# project. Using II Express. I have a few small SASS files (.scss).

I'm running Windows 8.1 with IE 11. I tried debugging with Chrome but no difference. Still micro-freezing.

The fans on my computer fire up when I press F5. CPU usage for devenv.exe stays at around 10-15% as long as I'm debugging.

Reproducible if you download the durandal starter kit on a clean slate and try debugging with WE installed / enabled. http://durandaljs.com/get-started.html

This is making development awfully hairy for our team - do you know how long a fix might take or should we seek alternative tools for the time being?

Guys, does v2.3.5 (nightly) make it better or worse?

Barryrowe commented 10 years ago

I have been unable to test the nightly build. I am running VS2013 Premium Update 3 (Version 12.0.30723.00 Update 3) and get an error when trying to install (2.4 it looks like is the current latest):

this extension is not supported on the current product.

I have also noticed that I only get this slowdown AFTER i have a problem with the extension failing to properly compile SCSS files. Here is the best detail I can give:

  1. Have a project with a main.scss file, everything is acting normally.
  2. Add a _base.scss file with some common variables and @mixins
  3. Save _base.scss (get an error about not being able to compile, possible syntax error, but it's trying to hit a compiling service at localhost and not getting a response)
  4. Add @import 'base'; to main.scss
  5. see the same errors about failing to compile and possible syntax errors
  6. Close the solution
  7. Close Visual Studio
  8. Open Solution
  9. Alter _base.scss and save (just adding a space or newline is enough)
  10. SCSS hopefully compiles (sometimes I have to restart VS more than once before this works with a valid scss file)
  11. Now my SCSS files are working, but when I'm running/debugging the app, VS is really lagging and almost unusable until I stop the debugger.

version 2.4 requires Update 4 RC
