Build Runtime License option missing in VS 2010

I am attempting to build a runtime license for a third party component for ASP.NET. The instructions are to place the "licenses.licx" file in the root folder of the site. The file is also embedded as a resource

However, the option to build the runtime license is not shown when I right click on the file.

There's also some confusion to what it is meant by the "ro开发者_Python百科ot folder of the site" Is it the root folder of the project?

It turns out that there is one vital step missing. I first have to open my solution as a web page, and move the license.licx to be in the same folder as the solution file.

Only when I open the solution as a web page, can I see files in the root folder inside the solution explorer. There I can right click on the license.licx file and see the option to build run-time license.
