ASP.NET how to set a variable in web.config during publising an app
I have an ASP.NET application and I would like to set a variable during publishing the application depending on the environment (like production, quality, etc....) I have created a variable in the web.config file in appsettings section inside configration section like this:
<add key="RunningEnvironment" value="dev"/>
I have two profiles when deploying dev and prod
How can I set the RunningEnvironment variable in the web.cong depending on the profile I choose when deploying ?
Take a look at web.config transformations.
In your Web.Production.Config for production environment set this:
<add xdt:Transform="Replace" xdt:Locator="Match(key)" key="RunningEnvironment" value="prod"/>
A handy tip you better know is Preview Transform dropdown menu option on Web.<ConfigurationName>.Config file in Visual Studio. There you will see all the changes that are going to take effect.
