How to get resource strings from ASP.NET markup?

Hi I have an assembly called like X.Common.DLL. There is some resources files for multilanguage app. Let's say it Language.resx Language.en-US.resx....etc....

I have a web application which contains this above dll as reference...

So how can I use this resources file in my web applications markup side?

Text="<%$ Resources:Class, ResourceKey %>" is not valid because of "Class" name is in another assembly...
