How to use applicationSettings in the new web.config configuration in VS2010?
The best way would be to do the following:
<applicationSettings> <NAMESPACE> <setting name="Testenvironment" serializeAs="String" xdt:Transform="Replace" xdt:Locator="Match(name)"> <value>True</value> </setting> </NAMESPACE> </applicationSettings> Rather than Zubeyir suggestion as this one will only replace the specifed setting rather than replacing the WHOLE of the applicationSettings section.
You could also use this way; for the prod environment for example.
<applicationSettings xdt:Transform="Replace"> <NAMESPACE> <setting name="Testenvironment" serializeAs="String"> <value>False</value> </setting> </NAMESPACE> </applicationSettings> Regards.
You should copy this setting to both web config files - Web.Debug.config and Web.Release.config and put the transformation attributes xdt:Transform="SetAttributes" xdt:Locator="Match(name)".
You can see this video tutorial - http://chriskoenig.net/index.php/2010/04/08/how-do-i-web-config-transformations-in-vs2010/
Hope that helps.
