Importing the Salesforce Winter 13 Metadata API to .NET

After updating the Metadata API to v29.0 from v28.0 I started getting the following SGEN compilation errors:

  1. Error 25 Unable to generate a temporary class (result=1). D:\...\SGEN
  2. Error 26 Cannot convert type 'XYZ.SalesforceMetadata.QuickActionLayoutItem[]' to 'XYZ.SalesforceMetadata.QuickActionLayoutItem' D:\...\SGEN
  3. Error 27 Cannot convert type 'XYZ.SalesforceMetadata.QuickActionLayoutItem[]' to 'XYZ.SalesforceMetadata.QuickActionLayoutItem' D:\...\SGEN

The QuickActionLayoutItem complexType from the v29.0 wsdl:

   <xsd:complexType name="QuickActionLayout">
    <xsd:sequence>
     <xsd:element name="layoutSectionStyle" type="tns:LayoutSectionStyle"/>
     <xsd:element name="quickActionLayoutColumns" minOccurs="0" maxOccurs="unbounded" type="tns:QuickActionLayoutColumn"/>
    </xsd:sequence>
   </xsd:complexType>
   <xsd:complexType name="QuickActionLayoutColumn">
    <xsd:sequence>
     <xsd:element name="quickActionLayoutItems" minOccurs="0" maxOccurs="unbounded" type="tns:QuickActionLayoutItem"/>
    </xsd:sequence>
   </xsd:complexType>
   <xsd:complexType name="QuickActionLayoutItem">
    <xsd:sequence>
     <xsd:element name="emptySpace" minOccurs="0" type="xsd:boolean"/>
     <xsd:element name="field" minOccurs="0" type="xsd:string"/>
     <xsd:element name="uiBehavior" minOccurs="0" type="tns:UiBehavior"/>
    </xsd:sequence>
   </xsd:complexType>

The problem appears in the generated Reference.cs with the quickActionLayoutColumns multidimensional array return type.

        /// 
        [System.Xml.Serialization.XmlArrayItemAttribute("quickActionLayoutItems",
              typeof(QuickActionLayoutItem), IsNullable=false)]
        public QuickActionLayoutItem[][] quickActionLayoutColumns {
            get {
                return this.quickActionLayoutColumnsField;
            }
            set {
                this.quickActionLayoutColumnsField = value;
            }
        }

The XmlArrayItemAttribute typeof(QuickActionLayoutItem) should be typeof(QuickActionLayoutItem[]). After changing this manually the web reference compiled again.

        /// 
        [System.Xml.Serialization.XmlArrayItemAttribute("quickActionLayoutItems",
              typeof(QuickActionLayoutItem[]), IsNullable=false)]
        public QuickActionLayoutItem[][] quickActionLayoutColumns {
            get {
                return this.quickActionLayoutColumnsField;
            }
            set {
                this.quickActionLayoutColumnsField = value;
            }
        }

  1. Should be use in case of VB.NET project.

    <System.Xml.Serialization.XmlArrayItemAttribute("columns",
    GetType(ListViewRecordColumn()),
