Adding Files Etc. as "Resources" to Visual Studio Projects

I recently wrote a unit test that needed some data that was too large to fit into a string literal.  To fix the problem, I added the file containing the string data as a resource to my project:

• In Solution Explorer, right click on the project Properties;
• Click on Open;
• Click on the Resources tab;
• Click on Add Resource and follow the dialogue for adding a file.

In the source code I can refer to the string contents of my resource file simply as

• MyNameSpace.Properties.Resources.MyResourceName

Of course, this scheme also works for data needed in other situations (e.g., logo images), not just unit tests.
