HttpContext.Current.IsDebuggingEnabled always true

Question

Why my site is running debug mode?

HttpContext.Current.IsDebuggingEnabled is always true!

Bundles not working!

Although #if DEBUG is false so DEBUG is not defined!

Precompilation is enabled on my appharbor app.

In my Web.Release.config I remove debug:

<system.web>
    <compilation xdt:Transform="RemoveAttributes(debug)" />
</system.web>

Online Transformation Tester give me this result tested with my Web.config and Web.Release.config:

Answer 1

I'm have the same issue. Temporarily, I'm using this workaround found in http://support.appharbor.com/kb/getting-started/managing-environments.

<add key="Environment" value="Debug"/>

Appharbor will replace the value="Debug" to the environment that was set in AppHarbor https://appharbor.com/applications/{appname}/edit

.

Instead of checking for HttpContext.IsDebugingEnabled, I'll check for

var isInDebugMode = ConfigurationManager.AppSettings["Environment"].Equals("Debug", StringComparison.InvariantCultureIgnoreCase));

Answer 2

When debugging from Visual Studio, your web.config transforms are NOT applied. This means your default Web.config likely has the line <compilation debug="true" targetFramework="4.6.1"/> , emphasizing the debug="true".

Removing the debug="true" attribute from the compilation element in your base Web.config file will make HttpContext.Current.IsDebuggingEnabled equal to false.

Some other options: If you are trying to see if the request is from your local machine, you can check for Request.IsLocal instead of HttpContext.Current.IsDebuggingEnabled, or to check for an active debugger Debugger.IsAttached

Interestingly enough, I am having the problem where Debugger.IsAttached is always returning true even on deployed production systems. – Mending
