Error while deserializing function with nullable return to xml

See original GitHub issue

Hi,

Autorest generated classes won’t compile when generating this json function:

"/api/DataManager/DoesTechnologyNameExistsInBrand": {
  "post": {
    "tags": [
      "DataManager"
    ],
    "operationId": "DataManager_DoesTechnologyNameExistsInBrand",
    "consumes": [
      "application/json",
      "text/json",
      "application/xml",
      "text/xml",
      "application/x-www-form-urlencoded"
    ],
    "produces": [
      "application/json",
      "text/json",
      "application/xml",
      "text/xml"
    ],
    "parameters": [
      {
        "name": "technologyName",
        "in": "query",
        "required": true,
        "type": "string",
        "x-nullable": true
      },
      {
        "name": "brandId",
        "in": "query",
        "required": true,
        "type": "integer",
        "format": "int32",
        "x-nullable": false
      },
      {
        "name": "technology",
        "in": "body",
        "required": true,
        "schema": {
          "$ref": "#/definitions/tblTechnology"
        }
      }
    ],
    "responses": {
      "200": {
        "description": "OK",
        "schema": {
          "type": "boolean",
          "x-nullable": false
        }
      }
    }
  }
},

This fragment:

bool? _tmp_ = null;
                    if (_httpResponse.Content.Headers.ContentType.MediaType == "application/xml" &&
                        XmlSerialization.Root(XmlSerialization.ToDeserializer(e => (bool)e))(System.Xml.Linq.XElement.Parse(_responseContent), out _tmp_))
                    {
                        _result.Body = _tmp_;
                    }
                    else
                    {
                        _result.Body = Microsoft.Rest.Serialization.SafeJsonConvert.DeserializeObject<bool?>(_responseContent, Client.DeserializationSettings);
                    }

Generates an error:

Argument 2: cannot convert from ‘out bool?’ to ‘out bool’

Because out _tmp is bool but the variable is declared as bool?.

I’m experiencing the same problem - although it’s not just generating the same non-compiling method above - it’s also generating a missing method:

internal static LocalizedContentRequest XmlDeserialize(XElement payload)
{
    var result = new LocalizedContentRequest();
    var deserializeLocalizedContent = XmlSerialization.CreateListXmlDeserializer(XmlSerialization.ToDeserializer(e => LocalizedContent.XmlDeserialize(e)), null);
    IList<LocalizedContent> resultLocalizedContent;
    if (deserializeLocalizedContent(payload, "LocalizedContent", out resultLocalizedContent))
    {
        result.LocalizedContent = resultLocalizedContent;
    }
    return result;
}

Where .XmlDeserialize(e) in LocalizedContent.XmlDeserialize(e) doesn’t exist.

If XML support is only for a specific scenario, is it not possible to turn it off by default and enable by configuration switch?

The added complexity I have is that one of my operations has to return an XML document (it’s a signed XML document) - which seems to trigger this behaviour.
