A System.Resources.ResourceWriter object for the specified resource.
Fine grain resources can be added with the returned System.Resources.ResourceWriter by calling System.Resources.ResourceWriter.AddResource(string, string).
fileName should not be the same as that of any other persistable module, stand-alone managed resource, or the stand-alone manifest file.
The runtime calls the System.Resources.ResourceWriter.Close method when the dynamic assembly is saved.
Starting with the net_v20sp1_long, this member no longer requires System.Security.Permissions.ReflectionPermission with the System.Security.Permissions.ReflectionPermissionFlag.ReflectionEmit flag. (See Security Issues in Reflection Emit.) To use this functionality, your application should target the net_v35_long or later.
