While creating bundle using core service I am getting following exception: Unable to find http://www.mycompanyname.com/tridion/schema/prodpublish_bundle_schema:Metadata.

I am following below process:

1. Reading what type (prod publish or prod unpublish) of bundle I have to create.
   
   SchemaData bundleSchema =(SchemaData)TridionCoreServiceFactory.CreateCoreService().Read("tcm:222-21051-8", _ReadOption);

2. getting Virtual folder type scheam as Bundle
   
   SchemaData virtualFolderTypeSchema = TridionCoreServiceFactory.CreateCoreService().GetVirtualFolderTypeSchema(@"http://www.sdltridion.com/ContentManager/Bundle");

3. Creating new VirtualFolder and setting propties to make it Bundle

    VirtualFolderData bundle = new VirtualFolderData()
    {
        MetadataSchema = new LinkToSchemaData(){IdRef = bundleSchema.Id},
        TypeSchema = new LinkToSchemaData(){IdRef = virtualFolderTypeSchema.Id},
        //setting other properties like name ,description, location etc. 
    }
   

With the above code Core Service is trying to find namesapce used in provided MetadataSchema and ending with error

Unable to find http://www.mycompanyname.com/tridion/schema/prodpublish_bundle_schema:Metadata.

When I checked source of BundleType 'prodpublish_bundle' it really has thenamespace
