Error cs0246 the type or namespace name player could not be found

I am using unity to create a top-down 2d game and I keep getting the error Error cs0246 «The type or namespace name ‘Player’ could not be found (are you missing a using directive or an assembly reference?) It seems like I have looked everywhere but I can’t fix it as I am new to unity. This is the code

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlayerController : MonoBehaviour{

        public int playerId = 0;
        public Animator animator;
        public GameObject crosshair7;   

        private Player player;

        void Awake() {
            player = ReInput.players.GetPlayer(playerId);
        }

        void Update()
        {

            Vector3 movement = newVector3(Input.GetAxis("MoveHorizontal"),Input.GetAxis("MoveVertical"), 0.0f);

            if(player.GetButton("Fire")) {
                 Debug.Log("Fire");
            }

            Movecrosshair7();

            animator.SetFloat("Horizontal", movement.x);
            animator.SetFloat("Vertical", movement.y);
            animator.SetFloat("Magnitude", movement.magnitude);

            transform.position = transform.position + movement * Time.deltaTime;
        }
        private void Movecrosshair7() {
            Vector3 aim = new Vector3(player.GetAxis("AimHorizontal"), player.GetAxis("AimVertical"), 0.0f);

            if (aim.magnitude > 0.0f) {
                aim.Normalize();
                aim *= 0.04f;
                crosshair7.transform.localPosition = aim;
            }
        }
    }

using My.Players.Namespace;

Vector3 movement = newVector3(Input.GetAxis("MoveHorizontal"),Input.GetAxis("MoveVertical"), 0.0f);

Vector3 movement = new Vector3(Input.GetAxis("MoveHorizontal"), Input.GetAxis("MoveVertical"), 0.0f);

  It looks like your library project is missing the reference. I think template unfolding failed. Can you try re-creating the project?

• User55492 posted

  Yeah i got there is reference missing But my Question is Why? Even i Tried more than 10 times to re-create the project in Every possible way But still no way found to overcome this issue. Can you help me to override the problems?

  Thanks in Advance.

  Are you using Xamarin Studio on Windows?

• User55492 posted

  Yeah right i am using Xamarin Studio for Windows Version 5.0

• User352 posted

  Okay I can confirm this is an issue on Xamarin Studio for windows, I am alerting the XS team. You probably want to use XS for OSX or using Xamarin for Visual Studio.

• User55492 posted

  Currently i am using XS on Windows, not Xamarin for Visual Studio.

• User55492 posted

  So now what should i do? i mean please can you suggest me a better or alternative way to Create Xamarin.Forms Project So i can move on my Project.

  Thanks @JasonASmith? for reply

• User352 posted

  I can’t resolve your issue, the problem is a bug in Xamarin Studio for Windows. You will need to either use XS for OSX or Xamarin for Visual Studio until Xamarin Studio for Windows is fixed.

  Sorry

• User55492 posted

  OK, Thanks @JasonASmith?

• User1350 posted

  I had the same issue on OSX, I had to re-create the project.

• User56499 posted

  Also stuck. Xamarin Studio on Windows 8 trying to use Xamarin.Forms… I find it sad to waste my trial period doing nothing…

• User14 posted

  I’m able to successfully download and run Xamarin.Forms samples from http://github.com/xamarin/xamarin-forms-samples on Windows 8.1 with Xamarin Studio 5 (Android parts of the solutions only).

  Even without being able to create a new, blank solution from scratch, it’s fairly easy to pick one of the simpler sample apps and start modifying it. Don’t let the Xamarin Studio for Windows broken template hold you back @nikolajskov? , @RajivChowdhery?

• User56499 posted

  Thanks, @CraigDunn. I’ll give it a try.

• User57812 posted

  Fixed this on XS OSX by going into Project > Edit referencers and double clicking on «Xamarin.Forms.Core.dll» on the right-hand side menu. Doesn’t seem to do anything but the compile error went away.

• User63992 posted

  I am using v5.2.1 and if you use NuGet (Project | Add Packages…) to search for Xamarin.Forms it will add the relevant packages to your project and this should get rid of the error message.

• User96874 posted

  I was resolve it by Add Refrence of Project. Suppose your project is TestApp1, So to add its dll First select TestAPP1.Android >> Add >> Add Web Refrence >> Select TestApp1 Tab and Chose dll that required (TestApp1.dll) and click on Add. Now can build your project successfully.

• User122180 posted

  I find the solution for this problem. The reason for this error is the complier can not find the corresponding .dll files, so if you add the .NET Assembly path for that .dll file, you will solve the problem.

  right-click the «reference» of project, and enter the «Edit References…», then choose the «.NET Assembly» tab, click the «Browser..» button, navigate to the path of that .dll file, and make sure the right path be added in the reference, you
  will find everything is ok!

• User122180 posted

  PS: The platform is Windows 8.1 Professional Edition, and Xamarin Studio is version 5.7.1

• User122180 posted

  I found another solution for this problem. When I look through the setting files for project, I found something stange. For example, when I add the «POIApp» project to the «POITestApp» References, in the POITestApp.csproj file, there are something be added as follow:

  {921FF87A-B1A4-45AA-BBAB-77EBD858CEBF}
  POIApp
  True
  False

  But When I delete this following two lines from that file and save it:
  True
  False

  I found the problem be solved, the solution be bulid successfully. But the smart code intellsense still don’t work. And I’m
  searching the reason cause it.

  I have a Problem:
  The type or namespace name ‘PersistableBundle’ could not be found(are you missing a using directive or and assembly reference?) (CS0246)

• User236584 posted

  Hi. I have the same issue as ilyas above. I need this to work so i can continue with my app. I am trying to learn how to use xamarin and mvvm but this is very hard and confusing.

  I am using Xamarin from within visual studio 2015 enterprise.

  All i am trying to do is create a splash screen for my app, something which took me minutes in Apache Cordova.

  Hi I’m learning how to use a “Creating Custom Row Layouts” and I’m having the same issue with Visual Studio 2015, I’m getting an error on
  Error: The type or namespace name ‘TableItem’ could not be found(are you missing a using directive or an assembly reference?)

  Code example is from https://developer.xamarin.com/guides/android/userinterface/workingwithlistviewsandadapters/part3—customizingalistview’s_appearance/

  public class HomeScreenAdapter : BaseAdapter
  {
  ListView listView;

          List<TableItem> items;
          Activity context;
          public HomeScreenAdapter(Activity context, List<TableItem> items)
              : base()
          {
              this.context = context;
              this.items = items;
          }
          public override long GetItemId(int position)
          {
              return position;
          }
          public override TableItem this[int position]
          {
              get { return items[position]; }
          }
          public override int Count
          {
              get { return items.Count; }
          }
          public override View GetView(int position, View convertView, ViewGroup parent)
          {
              var item = items[position];
              View view = convertView;
              if (view == null) // no view to re-use, create new
                  view = context.LayoutInflater.Inflate(Resource.Layout.CustomView, null);
              view.FindViewById<TextView>(Resource.Id.Text1).Text = item.Heading;
              view.FindViewById<TextView>(Resource.Id.Text2).Text = item.SubHeading;
              view.FindViewById<ImageView>(Resource.Id.Image).SetImageResource(item.ImageResourceId);
              return view;
          }
      }
  

  My objective is to have the Android App display several rows for data that was consume from a REST server(Json serialization process).

  For those who are still facing CS0246 error using Visual Studio on Windows, I found a way to solve it.

  Right click on Solution >> Manage NuGet Packages for Solutions, select the «Browse» tab and search for «Xamarin.forms», then install the first one Xamarin.Forms.

  It solved my problem!

  a resposta dele funciona (caso venha Brasileiro aqui procurando uma solução)

• User249671 posted

  I solved the problem by setting the right solution platform. E.g for UWP set it to x86, set IOS and Andriod solution platform.
  For me everything worked fine.

• User326314 posted

  I was trying to solve the Error CS0246: The type or namespace name ‘Xamarin’ could not be found (are you missing a using directive or an assembly reference?) (CS0246).
  When I tried to see more into the warning section, I could see that the project name was exceeding the required length.
  Renaming the project solved the issue.

• User361757 posted

  Hi. I have the same problem, when i build the ios project. I have Visual Studio 2017 version 15.5.1 and Xcode 9.2

• User59780 posted

  starting to get the same issues using Visual Studio 2017. Apps has been working just fine now today… same issues everyone is having. I have the latest visual studio too. smh. Microsoft need to get rid of Xamarin Studio. Kill that project 100%. Everything should be done EASILY inside Visual Studio. Every tutorial online should be ONLY visual studio. Create a migration tool to move everyone’s code from Xamarin Studio to Visual Studio.

• User59780 posted

  For my solution, I had to uninstall Xamarin.Forms and reinstall Xamarin.Forms. it works now.

• User59780 posted

  stopped working again.. lol and all I did was restart VS.
