Well as the title says i have 2 web projects that have the same css files, master page and some resource files, how could i share those? atm i have 2 copies of them...
Solution 1: bind them into separate assemblies in share it across your projects.
Reference:
Here is an article that describes how to share pages and user controls between applications : HOW TO: Share ASP.NET Pages and User Controls Between Applications by Using Visual Basic .NET. It's solution depends on separate virtual directory that holds the shared files.
And in this article Scott Guthrie describes how to build reusable web assemblies. It's solution depends on making separate assembly by shared files.
In the second project choose "Add existing file", select the file, click on the arrow on the add button and select "add as link".
