asp.net - CSS in App_Theme folder gets Cached in Browser

Question

The Stylesheet in the App_Theme folder gets cached in the browser. What should be the approach? so that whenever there is a new deployment the browser should take the latest stylesheets and not the one cached in the browser.

This was happening for other css(which are not in theme folder) too, so used custom control as mentioned in the link

How this could be done for the CSS in the Theme folder?

Edit: The theme name is mentioned in the web.config as mentioned below. so its not just the html link tag which I had solved by using the method mentioned in the link.

 <pages styleSheetTheme="Default">
      <controls>

      </controls>
    </pages>

I too have come across this and the solution I came up with is to add a version to your CSS filename, not pretty but without disabling cache on IIS I could think of no other way.

Rename the CSS file to say mycss-V1.0.css, which will force your user's web browsers to reload the CSS
