Answer 1

If you add the XML file to a Visual Studio project and, in the Property window for it, select Build Action: Embedded resource, the file will be embedded into the build output artifact for that project.

To access it from code, use something like:

string resourceName = "Namespace.Prefix.FileName.xml";
Assembly someAssembly = LoadYourAssemblyContainingTheResource();
XmlDocument xml = new XmlDocument();
using (Stream resourceStream = someAssembly.GetManifestResourceStream(resourceName))
{
    xml.Load(resourceStream);
}
// The embedded XML resource is now available in: xml

If the resource you’re loading is embedded in your own assembly, you can do something like Assembly.GetExecutingAssembly() to achieve what I listed as LoadYourAssemblyContainingTheResource() above, or possibly typeof(SomeTypeInYourResourceAssembly).Assembly

It’s unclear what you mean by “want to modify the contents” – you cannot modify the resource inside the assembly at run-time, but whenever you change the XML file and recompile, the new version will be embedded.
