Resource files can be used to store strings, images, audio files, and other binary or text files that will be used by your application.
Right-click on your project and
Add->New Item.... From here select
You can now drag resources right into the file.
In the background, a file is generated to reflect the added resources. Using the resource will look similar to
var resourceData = Resource.GetBytes(Resource.BinaryResources.data);
If you are copying example code that uses resource files, some changes may be needed to match the resources' names in your project.
