Can't find namespace even when having the 'using'?

I am using Unity and I'm getting a 'The type or namespace name 'Mine' could not be found (are you missing a using directive or an assembly reference?)' error. I know this means that you are usually missing a using statement, but this is not the case this time. Take a look at the beginning of the 2 script at question. The error is flagged at "public WarmList list;"
using UnityEngine;
using Mine;
namespace PolymindGames.BuildingSystem
{
[RequireComponent(typeof(CookingStation))]
//public class CampfireEffects : MonoBehaviour
public sealed class CampfireEffects : MonoBehaviour
{
public WarmList list;
...
}
}
And script 2
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
namespace Mine
{
public class WarmList : MonoBehaviour
{...
}
}
Why can't script one see class 2? I don't think I am doing anything wrong? I have tried so many solutions but nothing works, I keep getting that complier error.

Unable to detect error while using PhotonView.isMine method

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Photon.Pun;
using Photon.Realtime;
using System.IO;
using UnityEngine.UI;
public class PhotonPlayerSetup : MonoBehaviourPunCallbacks, IInRoomCallbacks
{
private PhotonView PV;
void Awake()
{
PV = GetComponent<PhotonView>();
}
void Start()
{
if(PV.isMine)
{
}
}
}
While using above mentioned code this error appears:
"PhotonView does not contain a definition for isMine and no
accessible extension method isMine accepting a first argument of
type 'PhotonView' could be found (are you missing a using directive or
an assembly reference?)"

Thank you for choosing Photon!
PhotonView.isMine from PUN Classic was renamed to PhotonView.IsMine in PUN 2.

C# cant find a unity auto generated class

Okay so I'm learning to use the new InputActions and I've created a C# scripts using
https://prnt.sc/oyaj5l
And this is what I got:
// GENERATED AUTOMATICALLY FROM 'Assets/PlayerControls.inputactions'
using System.Collections;
using System.Collections.Generic;
using UnityEngine.InputSystem;
using UnityEngine.InputSystem.Utilities;
public class PlayerControls : IInputActionCollection
{
private InputActionAsset asset;
public PlayerControls()
{
///
}
}
But when I try to create an PlayerControls object, I get an error saying
The type or namespace name 'PlayerControls' could not be found (are you missing a using directive or an assembly reference?)
This is the class where I try to reference it:
using System;
using UnityEngine;
using System.Collections;
using UnityStandardAssets.CrossPlatformInput;
using UnityStandardAssets.Utility;
using Random = UnityEngine.Random;
using UnityEngine.InputSystem;
namespace UnityStandardAssets.Characters.FirstPerson
{
public class FirstPersonController : MonoBehaviour
{
private PlayerControls controls; // ERROR HERE
}
}

Wrap the PlayerControls class in a namespace, then add a using statement in your class that points to the namespace where your PlayerControls class lives.

I solved it!
It looks like Unity has a compile order. I referenced this: http://answers.unity.com/answers/1274460/view.html and managed to solve it after seeing that "Standard Assets" has priority over other assets

Type or namespace name 'IUnzipper' could not be found

I am trying to run a simple implementation of Virtual Buttons in Unity using Vuforia.
My current versions are : Unity 5.6.1
And I'm recieving Type or namespace 'IUnzipper' could not be found (are you using a missing directive or assembly reference?)
My C# Script :
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Vuforia;
public class vbScript : MonoBehaviour, IVirtualButtonEventHandler {
GameObject zombie;
// Use this for initialization
void Start () {
zombie = GameObject.Find ("zombie");
GameObject virtualButtonObject = GameObject.Find ("actionButton");
virtualButtonObject.GetComponent<VirtualButtonBehaviour> ().RegisterEventHandler (this);
}
public void OnButtonPressed(VirtualButtonAbstractBehaviour vb) {
Debug.Log("button Pressed");
zombie.GetComponent<Animation> ().Play ();
}
public void OnButtonReleased(VirtualButtonAbstractBehaviour vb) {
zombie.GetComponent<Animation> ().Stop ();
}
}
Error trace:
\VirtualButton3\Assets\Vuforia\Editor\Scripts\Unzipper\SharpZipLibUnzipper.cs(38,38): Error CS0246: The type or namespace name 'IUnzipper' could not be found (are you missing a using directive or an assembly reference?) (CS0246) (Assembly-CSharp-Editor)

Google is a great resource.
It appears that the template dose not always come with it in the folder.

PointToClient not quite working. (Error details within.)

i'm working on a tower defence for a class exam together with a friend of mine. And i figured i would use "PointToClient" To get the positions of the cursor to send with the tower when ever we want to put it down. But its not quite working. I keep getting the error:
'Vp.PlaceTower'does not contain a definition for 'PointToClient' and no extension method 'PointToClient' accepting a first argument of type 'Vp.PlaceTower' could be found (Are you missing a using directive or an assembly reference?).
The code is as follows;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Drawing;
using System.Windows.Forms;
using System.ComponentModel;
using System.Data;
namespace Vp
{
class PlaceTower : GameWorld
{
private List<Tower> towers = new List<Tower>();
private Point cursorPos;
private Point position;
private Point oldCursorPos;
public void PlaceTower()
{
cursorPos = this.PointToClient(Cursor.Position);
}
}
}

PointToClient is a method that belongs to the class System.Windows.Forms.Control. Does GameWord inherit this class? Your exception is very explanatory.
Make GameWorld inherit Control and you will solve this.
