/resource (C# Compiler Options)
Embeds the specified resource into the output file.
Use /linkresource to link a resource to an assembly and not add the resource file to the output file.
By default, resources are public in the assembly when they are created by using the C# compiler. To make the resources private, specify private as the accessibility modifier. No other accessibility other than public or private is allowed.
If filename is a .NET Framework resource file created, for example, by Resgen.exe or in the development environment, it can be accessed with members in the System.Resources namespace. For more information, see ResourceManager. For all other resources, use the GetManifestResource* methods in the Assembly class to access the resource at run time.
/res is the short form of /resource.
The order of the resources in the output file is determined from the order specified on the command line.
