applicationhost.config inside hidden .vs folder

Question

can some help me because i am really confused. Using Visual studio, in my App folder i have a hidden folder named .vs , inside another folder config and next an applicationhost.config .

This config file, when used and for who is important to have? If i published my web app thought IIS, this file used in someway?

I can see that inside this config file exist node applicationPools and sites like this that IIS have. So why this config file have global settings for IIS and is stored inside my Apps folder and not somewhere more 'outside'?

When i run local my app this config used? Or only when is on IIS, or both?

I really have no idea why and how use applicationhost.config but if i wanted to change user credentials that App run what should change?

        <applicationPoolDefaults managedRuntimeLoader="v4.0">
           <processModel identityType="SpecificUser" userName="username" password="password" />
        </applicationPoolDefaults>

I'm not shure if you are locally testing your website using IIS or rather IIS Express .

• The file in .vs is used to configure IIS Express , when you start your website from Visual Studio.
• When you publish your app to IIS this file is ignored .

If you whant to publish settings for IIS, you can include those in the section <system.webServer> in your Web.config file. Those settings will then be added to the IIS configuration, you deploy to.

Hope this makes things a bit clearer.
