As the title suggests, my IISExpress will recompile everything if I make a change to any of the javascript (or css, cshtml or typescript files). This means I have to wait 15 to 60 seconds to see a javascript change reflected in the browser.
It happens in both Visual Studio 2013 and 2015.
I assume there's a configuration problem in Visual Studio, the project or IISExpress, but I have been unable to figure out what to change, or even where to start looking.
Any help or guidance is greatly appreciated.

I'm using Node.js tools for Visual Studio 2015. All ES6 features under Node.js tools options are turned on. I've tried turning them off too. I've also tried setting JavaScript files not to display syntax highlighting.
Visual Studio displays tons of errors for files containing ES6 JavaScript (the content of the files are actually just fine by ES6 standards).
Interestingly, if I double click on any of the errors, I get a message
So, it seems that maybe VS is "double-inspecting" these files...and the second pass fails. Because if I open the file in question from solution explorer, there is no run underlining anywhere in the file?
I've spent a long time troubleshooting this. Is there any way to make Visual Studio work, a little bit?
What version of Node.js Tools for Visual Studio are you using? You may just need to update to the latest version.
I had this same problem with version 1.1.31117.00, but I'm not seeing it anymore with 1.2.40726.00.
Below is the error that I is displayed when in tried to run Orchard (1.10 and 1.10.1) source from Visual studio 2015 community version.
I know that it is somehow related with configuration settings, but I am unable to solve it.
The same files, when placed in the local IIS runs without any problems. Is there anything that I am missing in visual studio 2015?
How to resolve this error?
Is the displayed 'Config file' path corresponding to your folder?
Because it doesn't seem to be a folder coming from the source code.
Sometime, IIS Express messes up when you try to launch a site with the same port that a previously used one.
Try to read your applicationhost.config (see IIS Express in tasks bar to get the path).
You could also try to change the port in Orchard.Web properties.
I am using visual studio pro 2012 edition, one of our developers updated the wsdl definitions on a webservice without telling us and for a while i couldnt figure out why the wsdl definitions werent being updated. I did clean and build of the services, stopped the site and even exited IIS Express. Turns out if you have the solution open in visual studio with the old wsdl definition, the new definitions are not updated after pulling latest(svn). I tried several times and the only solution is to close visual studio and restart using the latest codebase.
anyone else experience this? could be a bug in vs2012 only?
I figured out what happened, my colleague copied over the hidden folder .vs folder which had the applicationhost.config file pointing to their username, vs2012 does not give any errors and happily runs the service but it serves the old pages. VS2015 shows an error page which is how i found out the problem.
Background
I maintain several web sites that are Visual Studio "Web Site Projects".
Problem
I've found that with a couple of these projects, Visual Studio regularly freezes while I'm working on the code. This doesn't happen for some of the web site projects, and I haven't seen it happen on any Web Application projects.
Symptoms
Each time it freezes, it takes about half a minute before I can use it again.
During a freeze, Windows Task Manager reports that Microsoft.VisualStudio.Web.Host.exe is maxing out one of the CPU cores.
Steps to Reproduce
Open a .cs file under the App_Code directory.
Make a change to the file.
Save the file.
Navigate somewhere else (eg switch tab, close the file, open different program in Windows).
Navigate back to the file (eg switch tab to it, open it, or go back to Visual Studio).
Other actions that sometimes seem to trigger the problem:
"Go to definition"
Opening a file
Previewing a file
Closing a file
Using a refactoring
"Find usages"
What I've Tried
Both Visual Studio 2012 and Visual Studio 2015
Changing the website project's build action
Disabling "Build Web site as part of solution"
Deleting web references and the Bin folder seems to minimise the problem, but obviously this breaks the web site. Maybe web site projects experience this problem when they contain a lot of C# code other than code-behind files?
Similar problems
I found the following potentially-related problems using Google, but none of them seemed to contain a workaround or solution.
Microsoft.VisualStudio.Web.Host.exe Time Theft
Microsoft.VisualStudio.Web.Host.exe
Visual Studio 2012 freezes for approximately 30 seconds after every build
I noticed that the problem happened less often when I suspended ReSharper.
The problem still happened occasionally when editing classes under App_Code, but restarting Visual Studio worked around it.
I was facing a similar problem. A single Web application project with dozens of class libraries, migrated over from VS 2010 into VS 2013.
I was able to solve my problem by disabling the "Hosting Process" option:
To disable the hosting process
Open an executable project in Visual Studio. Projects that do not
produce executables (for example, class library or service projects)
do not have this option.
On the Project menu, click Properties.
Click the Debug tab.
Clear the Enable the Visual Studio hosting process check box.

Another option for people experiencing this on old web applications that don't have the properties page in the accepted answer above.
Disable "Allow this precompiled site to be updatable".
Open Site/Solution
Right click and view Property Pages
Go to MSBuild Options
Uncheck "Allow this precompiled site to be updatable"
This worked for me.
This problem stopped happening when the Web Site project was converted into a Web Application project.
Not an easy solution, but it did stop the problem.
They symptoms in the question of this post sound exactly like the nightmares I just had today:
Other actions that sometimes seem to trigger the problem:
"Go to definition"
Opening a file
Previewing a file
Closing a file
Using a refactoring "Find usages"
Plus intellisense wasn't working (even with CTRL + J) and
'Peek definition' was hanging as well.
I had to keep task killing visual studio (both 2015 and 2017).
My fix was to go into the project that I was having problems with, open the 'Package Manager Console' and uninstall and re-install the 'DotNetCompilerPlatform'
uninstall-package Microsoft.CodeDom.Providers.DotNetCompilerPlatform
and then
install-package Microsoft.CodeDom.Providers.DotNetCompilerPlatform
So far every problem I was encountering has not resurfaced (but this was just today so still need to give it time).
UPDATE:
It started creeping back again. I noticed also that whomever had installed to the solution had only done it to two of the various projects. Uninstalling the compiler platform (which means using the compilers that came with Visual Studio) has made life sane again.
An interesting things is happening and I was hoping someone would be able to help me with it.
Visual Studio 2012 with Web Essentials installed was working fine until the latest update (the one where they removed less, coffeescript, etc.)
However since the update, I am having problems. This only happens when I open a project that has a file - which web essentials would act upon - already open.
If I close all of the tabs with cshtml/less/css files before I close a project. Then the next time I open that project, I am fine. I can even open those files, and web essentials kicks in with all of its extra features. But if even one of those files are open when the project was saved, and therefore opened automatically when the project is loaded, then the entire visual studio crashes.
Any help would be appreciated.
Thank you
Found the issue after days and days of searching (only minutes after posting this question :))
The latest version of Web Essentials requires ASP.NET and Web Tools 2012.2
I had heard a lot about these Tools 2012.2 but I thought that they were an extension - maybe the "Microsoft Web Development Tools" installed automatically with visual studio or something that would get upgraded automatically with all of the auto updating software running on my machine.
So I tried updating all of the extensions and refreshing and refreshing and searching for updates - to no avail.
I even downloaded and installed VS2012 Update 2 CTP4 thinking that that must be this elusive update that everyone is talking about.
Well as I'm sure you guessed, its actually none of the above.
The link is http://go.microsoft.com/fwlink/?LinkId=282650
It is listed on the home page of web essentials but not on the page that pops up when you run the update.
I hope this link helps someone.
