Question: How to create an embedded resource in a Web Site project?

In a web application project I can change the 'build action' through the properties window of a file. In an Web Site project there is no properties window. I noticed, in a web application project, the .csproj file is changed when you change the build action of a file. In a Web site project there is no .csproj file of course. 

Is it possible to create an embedded resource in an Web Site project?

In mainwhile, we changed the project to a web application project. But I'm still curious..

Answer: 
You can't add an embedded resource, because web site projects are not pre-compiled. There is no generated dll to embed the resource in.
You can still get a properties window on a Web Site project - do you mean that you want to mark an item in your website project to be included for deployment? If so that would be done by setting the Build Action property for the selected file in your solution to Content.

Embedded Resource is an option but is aimed at items you wish to embed within the compiled DLL corresponding to your App\_Code. You would then need to load the resource from your assembly.
