Answer 1

The problem is because System namespace in both Windows and BAPI. This can be dealt with by adding global:: before all calls giving the above errors. This does not involve editing WSDL.

Answer 2

Since this issue is caused by naming conflict in .NET and SAP, another workaround for this issue without changing SAP configuration：

Add an alias for System.XML as below in Reference.cs

using SysXml = System.Xml;

Then, replace all the System.Xml where report the error with "SysXml" as below (please note that the word "SysXml" is originally "System.Xml" after adding the service, which caused this issue)

/// <remarks/>
[System.Xml.Serialization.XmlElementAttribute(Form=SysXml.Schema.XmlSchemaForm.Unqualified)]
public string Type {
    get {
        return this.typeField;

    set {
        this.typeField = value;
    }
}
