Error 1: does not implement interface member

Question

I am creating an multiplayer server based on photon using CRJ Gaming tutorials i have ran into this error, been trying to fix it for more than 2 hours, rewatched tutorials few times, i am completely lost.

Erorr:

The error message gives you everything you need to know.

PhotonServerHandler is an abstract class which implements the interface IHandler

This means that all methods that are declared within the IHandler, must be implemented within PhotonServerHandler.

Here is a solid example of why you would get that error

public interface A
{
    void DoThingOne();
    void DoThingTwo();
} 

public abstract class B : A
{
    DoThingOne()
}

The above would throw an error.

If you are using visual studio, try right clicking on the interface, then implement interface.

that should implement all the necessary methods from the interface.

Ihave written HandleMessge instead of HandleMessAge, I single letter lost me 2 hours. Thank you very much. – Pencho Slaveikov Mar 22 '15 at 15:44
Harsh! No worries. Glad you got it sorted :) – PolymorphicPhantom Mar 22 '15 at 16:09
