Hi I'm trying to run dotless on my local .net4 web site
My web config looks like this:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<section name="dotless" type="dotless.Core.configuration.DotlessConfigurationSectionHandler, dotless.Core" />
</configSections>
<system.web>
<compilation debug="true" targetFramework="4.0" />
<httpHandlers><add path="*.less" verb="GET" type="dotless.Core.LessCssHttpHandler, dotless.Core" /></httpHandlers></system.web>
<dotless minifyCss="false" cache="true" web="false" />
<system.webServer>
<handlers>
<add name="dotless" path="*.less" verb="GET" type="dotless.Core.LessCssHttpHandler,dotless.Core" resourceType="File" preCondition="" />
</handlers>
</system.webServer>
</configuration>
Here is the error I get
HTTP Error 500.23 - Internal Server Error
An ASP.NET setting has been detected that does not apply in Integrated managed pipeline mode.
Most likely causes:
This application defines configuration in the system.web/httpHandlers section.
Can you please help?
adding <validation validateIntegratedModeConfiguration="false"/>
worked
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<section name="dotless" type="dotless.Core.configuration.DotlessConfigurationSectionHandler, dotless.Core" />
</configSections>
<system.web>
<compilation debug="true" targetFramework="4.0" />
<httpHandlers>
<add path="*.less" verb="GET" type="dotless.Core.LessCssHttpHandler, dotless.Core" />
</httpHandlers>
</system.web>
<dotless minifyCss="false" cache="true" web="false" />
<system.webServer>
<validation validateIntegratedModeConfiguration="false"/>
<handlers>
<add name="dotless" path="*.less" verb="GET" type="dotless.Core.LessCssHttpHandler,dotless.Core" resourceType="File" preCondition="" />
</handlers>
</system.webServer>
</configuration>
<validation validateIntegratedModeConfiguration="false"/>
tells IIS to ignore configuration issues. One such issue seems to be the fact that dotless automatically adds a handler to system.web
and system.webServer
. The former section is used by the classic application pool mode, whereas the latter by the new integrated application pool mode. Since I am using the integrated mode, removing the handler in system.web helped just as well.
I had to add <validation validateIntegratedModeConfiguration="false"/>
to my webserver section and I also had to move the configSections to be the first element in my Configuration.
<configuration>
<configSections>
<section name="dotless" type="dotless.Core.configuration.DotlessConfigurationSectionHandler, dotless.Core" />
We will add a small piece of code into web.config file. open web.config from your IIS root or change the setting in Visual Studio web.config and publish again.
<system.webServer>
<validation validateIntegratedModeConfiguration="false"/>
</system.webServer>
