  • Question

  • Could anyone help me understand this error response? 

    <string xmlns="">Hello%21+World</string>
    <string xmlns="">This+is+a+test+string.+</string>
    <string xmlns="">For+example%2C+we+have+translated+some+or+all+of+the+information+on+this+page+with+machine+translation+software+so+some+of+the+translations+may+not+be+entirely+correct</string>


    response:Unable to deserialize XML body with root name 'translatearrayrequest' and root namespace '' (for operation 'TranslateArray' and contract ('LanguageService',  '')) using DataContractSerializer. Ensure that the type corresponding to the XML is added to the known types collection of the service.
