Conversion from C# to VB inserting "Key" ???

In my following code (partial) the conversion adds  "Key ."
Which gives me an error on code in VB.
How do I handle this?

THIS CODE

                    using (SJVServiceClient client2 = new SJVServiceClient())
                    {
                        SearchResult res2 = new SearchResult();
                        res2 = client.GetResult(new GetResultRequest
                        {
                            RequestID = requestID,
                            Authentication = new Authentication
                            { UserName = "username", Password = "password6" }
                        });

                        if (res2.ProductResult != null)
                        {
                            var json = JsonConvert.SerializeObject(res2);
                            lblJason.Text = json.ToString();
                        }
                    }

Select allOpen in new window

Produces THIS CODE

Using client2 As New SJVServiceClient()
	Dim res2 As New SearchResult()
	res2 = client.GetResult(New GetResultRequest() With { _
		[b]Key [/b].RequestID = requestID, _
		Key .Authentication = New Authentication() With { _
			Key .UserName = "username", _
			Key .Password = "password" _
		} _
	})

	If res2.ProductResult IsNot Nothing Then
		Dim json = JsonConvert.SerializeObject(res2)
		lblJason.Text = json.ToString()
	End If
End Using
