Hi,
the appended picture "intellisense.png" shows the problem. Intellisense does not recognize that print() is a member function WifiClient. Compiling the project works fine without an error.

WifiClient inherits from Client (with a suspicious error message (see picture "client.png")) inherits from Stream inherits from Print which has a member print().

I'm using:
- Microsoft Visual Studio Community 2015
  Version 14.0.24720.00 Update 1
- Visual Micro Version 1.1603.20
- ESP8266 Version 2.1.0
- Arduino 1.6.8

The Code from a fresh test project:
-------------------------------------------------
#include <WiFiUdp.h>
#include <WiFiServer.h>
#include <WiFiClientSecure.h>
#include <WiFiClient.h>
#include <ESP8266WiFiType.h>
#include <ESP8266WiFiSTA.h>
#include <ESP8266WiFiScan.h>
#include <ESP8266WiFiMulti.h>
#include <ESP8266WiFiGeneric.h>
#include <ESP8266WiFiAP.h>
#include <ESP8266WiFi.h>
void setup()
{ WiFiClient wc;
   wc.print("");
}

void loop()
{
}

Hi Tim,

I don't understand your first question. All inheritance is public. Is that the answer you want?
- class WiFiClient : public Client, ...
- class Client: public Stream ...
- class Stream: public Print ...

F12 (pressed wit selected Client.println at the .ino-file) shows the correct definiton. See Attachment.

Kind regards
