Copy data from one db to another in linqpad

I wanted to pull a single row of data from one db on one server to another db on another server. using C# and LinqPad. This looks like it would have worked, if I had the matching db on localhost.
void Main()
  this.DeferredLoadingEnabled=false; //critical to ignore navigation properties
  var oldcon= this.Connection;
  var user =Users.First (u => u.User_Name=="dummyuser").Dump();
  var settings=new Newtonsoft.Json.JsonSerializerSettings(){ NullValueHandling= NullValueHandling.Ignore, ReferenceLoopHandling= ReferenceLoopHandling.Ignore, MaxDepth=1  };
  var serUser= JsonConvert.SerializeObject(user, 
  var myConString=oldcon.ConnectionString.Replace("devdb\\be","localhost").Dump();
  var otherCon= new System.Data.SqlClient.SqlConnection(myConString);
  var otherContext=new TypedDataContext(otherCon); 
  otherContext. Users.Attach((User)JsonConvert.DeserializeObject<User>(serUser.ToString()));
