Display a scene

Before starting this tutorial:

• You need an ArcGIS Location Platform or ArcGIS Online account.

• Ensure your development environment meets the system requirements.

Optionally, you may want to install the ArcGIS Maps SDK for .NET to get access to project templates in Visual Studio (Windows only) and offline copies of the NuGet packages.

Option 1: Develop the code

Create a new Visual Studio Project

ArcGIS Maps SDK for .NET supports apps for Windows Presentation Framework (WPF), Windows UI Library (WinUI), and .NET MAUI. The instructions for this tutorial are specific to creating a WPF .NET project using Visual Studio for Windows.

1. Start Visual Studio and create a new project.

   • In the Visual Studio start screen, click Create a new project.
   • Choose the WPF App (.NET) template for C#, then click Next.
   • Provide required values in the Configure your new project panel:
     • Project name: DisplayAScene
     • Location: choose a folder
   • Click Create to create the project.

More info

If you are developing with Visual Studio for Windows, ArcGIS Maps SDK for .NET provides a set of project templates for each supported .NET platform. These templates follow the Model-View-ViewModel (MVVM) design pattern. Install the ArcGIS Maps SDK for .NET Visual Studio Extension to add the templates to Visual Studio (Windows only). See Install and set up for details.

Add a reference to the API

1. Add a reference to the API by installing a NuGet package.

   • In Solution Explorer, right-click Dependencies and choose Manage NuGet Packages.
   • In the NuGet Package Manager window, ensure the selected Package source is nuget.org (upper-right).
   • Select the Browse tab and search for ArcGIS Maps SDK.
   • In the search results, select the appropriate package for your platform. For this tutorial project, choose the Esri.ArcGISRuntime.WPF NuGet package.
   • Confirm the Latest stable version of the package is selected in the Version dropdown.
   • Click Install.
   • The Preview Changes dialog confirms any package(s) dependencies or conflicts. Review the changes and click Apply to continue installing the packages.
   • Review the license information on the License Acceptance dialog and click I Accept to add the package(s) to your project.
   • In the Visual Studio Output window, ensure the packages were successfully installed. If you see an error about the target Windows version, you will fix that in the next step.
   • Close the NuGet Package Manager window.

2. You may see an error like this in the Visual Studio Error List: The 'Esri.ArcGISRuntime.WPF' nuget package cannot be used to target 'net8.0-windows'. Target 'net8.0-windows10.0.19041.0' or later instead.. If so, follow these steps to address it.

   • In Solution Explorer, right-click the project entry in the tree view and choose Edit Project File.
   • Update the <TargetFramework> element with net8.0-windows10.0.19041.0 (or higher).

   <PropertyGroup>
     <OutputType>WinExe</OutputType>
     <TargetFramework>net8.0-windows10.0.19041.0</TargetFramework>
     <UseWPF>true</UseWPF>
   </PropertyGroup>
   • Save the project file and close it.

Create a view model to store app logic

Since this app builds the foundation to be used in several following tutorials, it’s good to build it with a solid design.

More info about the MVVM design pattern

The Model-View-ViewModel (MVVM) design pattern provides an architecture that separates user interface elements, and related code, from the underlying app logic. In this pattern,model represents the data consumed in an app, view represents the user interface, and view model contains the logic that binds model and view together. The framework required for such a pattern might initially seem like a lot of work for a small project, but as your project’s complexity increases, a solid design foundation will make your code more flexible and easier to maintain.

In an ArcGIS app designed with MVVM, the map view A map view is a user interface that displays map layers and graphics in 2D. It controls the area (extent) of the map that is visible and supports user interactions such as pan and zoom. Learn more or scene view A scene view is a user interface that displays scene layers and graphics in 3D. It uses a camera to control the visible area of the scene and supports user interactions such as pan, zoom, tilt, and rotate. Learn more usually provides the main view component. Many of the classes fill the role of model (representing data as maps, scenes, layers, graphics, features, and others). Much of the code you write will be for the view model component, where you will add logic to work with ArcGIS objects and provide data for display in the view.

1. Add a new class that defines a view model for the project.

   • Click Project > Add Class ….
   • Name the new class SceneViewModel.cs.
   • Click Add to create the new class and add it to the project.
   • The new class will open in Visual Studio.

2. Add required using statements to the view model.

   SceneViewModel.cs

   using System;
   using System.Collections.Generic;
   using System.Text;
   
   using Esri.ArcGISRuntime.Geometry;
   using Esri.ArcGISRuntime.Mapping;
   using System.ComponentModel;
   using System.Runtime.CompilerServices;

3. Implement the INotifyPropertyChanged interface in the SceneViewModel class.

   More info

   This interface defines a PropertyChanged event that is used to notify clients (views) that a property of the view model has changed.

   SceneViewModel.cs

   namespace DisplayAScene
   {
   
       class SceneViewModel : INotifyPropertyChanged
       {

4. Inside the SceneViewModel class, add code to implement the PropertyChanged event.

   More info

   When a property of the view model changes, a call to OnPropertyChanged will raise this event.

           {
               get { return _scene; }
               set
               {
                   _scene = value;
                   OnPropertyChanged();
               }
           }
   
       }

       }
   
   }

7. Create an ElevationSource to define the base surface for the scene.

   More info about elevation sources

   One or more elevation sources can be used to define a base surface in a scene. The base surface represents the ground height and all other layers in a scene are aligned relative to its height. Without a base surface, the default globe surface is used to display data in the scene.

   }

8. Define the initial viewpoint for the scene using a Camera and a point in the scene.

   Camera settings

   The position you view the scene from is defined by a Camera. The following properties of the camera are used to define an observation point in the scene:

   • 3D location: Latitude, longitude, and altitude
   • Heading: Azimuth of the camera’s direction
   • Pitch: Up and down angle
   • Roll: Side-to-side angle

10. Add a constructor to the class that calls SetupScene when a new SceneViewModel is created.

    More info

    When code like SceneViewModel newSceneVM = new SceneViewModel(); runs, the class constructor also runs. This is a good place to add code that needs to run whenever the class is initialized.

Your SceneViewModel is complete!

An advantage to using the MVVM design pattern is that you can reuse code from a view model. Because this API has a nearly-standard API surface across platforms, a view model written for one app typically works on all supported .NET platforms.

Set developer credentials

To allow your app users to access ArcGIS Location Services ArcGIS Location Services, also referred to as Location Services, are services hosted by Esri that provide geospatial functionality for developing mapping applications. They include the ArcGIS Basemap Styles service, ArcGIS Static Basemap Tiles service, ArcGIS Places service, ArcGIS Geocoding service, ArcGIS Routing service, ArcGIS GeoEnrichment service, and ArcGIS Elevation service. An ArcGIS Location Platform or ArcGIS Online account is required to use the services. Learn more , use the developer credentials that you created in the Set up authentication step to authenticate requests for resources.

API key authentication User authentication

1. In the Solution Explorer, expand the node for App.xaml, and double-click App.xaml.cs to open it.

2. In the App class, add an override for the OnStartup() function to set the ApiKey property on ArcGISRuntimeEnvironment.

   App.xaml.cs

       public partial class App : Application
       {
   
           protected override void OnStartup(StartupEventArgs e)
           {
               base.OnStartup(e);
   
               // Set the access token for ArcGIS Maps SDK for .NET.
               Esri.ArcGISRuntime.ArcGISRuntimeEnvironment.ApiKey = "YOUR_ACCESS_TOKEN";
   
           }
   
       }
   }

3. Replace “YOUR_ACCESS_TOKEN” with the API key access token you created earlier.

4. Save and close the App.xaml.cs file.

Best Practice: The access token is stored directly in the code as a convenience for this tutorial. Do not store credentials directly in source code in a production environment.

Next, set up a view in your project to consume the view model.

Add a scene view

A SceneView control is used to display a Scene. You will add a scene view to your project UI and wire it up to consume the scene that is defined on SceneViewModel.

1. Add required XML namespace and resource declarations.

   More info

   • Open MainWindow.xaml and switch to the XAML view
   • Inside the existing namespace declarations, add an esri XML namespace for the ArcGIS controls
   • Add XAML that defines a SceneViewModel instance as a static resource
   MainWindow.xaml

   <Window x:Class="DisplayAScene.MainWindow"
           xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
           xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
           xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
           xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
           xmlns:local="clr-namespace:DisplayAScene"
           xmlns:esri="http://schemas.esri.com/arcgis/runtime/2013"
           mc:Ignorable="d"
           Title="MainWindow" Height="450" Width="800">
   
       <Window.Resources>
           <local:SceneViewModel x:Key="SceneViewModel" />
       </Window.Resources>
   6 collapsed lines
   
       <Grid>
   
       </Grid>
   
   </Window>

2. Add a SceneView control to MainWindow.xaml and bind it to the SceneViewModel.

   More info

   • Add XAML that defines a SceneView control named MainSceneView
   • Use data binding to set the Scene property of the control using the SceneViewModel resource
   MainWindow.xaml

           <esri:SceneView x:Name="MainSceneView"
                           Scene="{Binding Scene, Source={StaticResource SceneViewModel}}" />
   
       </Grid>

Option 2: Download the solution

1. Click the Download solution link in the right-hand panel of the page.

2. Unzip the file to a location on your machine.

3. Open the .sln file in Visual Studio.

Since the downloaded solution does not contain authentication credentials, you must add the developer credentials that you created in the Set up authentication section.

API key authentication User authentication

1. In Visual Studio, in the Solution Explorer, click App.xaml.cs to open the file.

2. Set the ArcGISEnvironment.ApiKey property with your API key access token.

   App.xaml.cs

           protected override void OnStartup(StartupEventArgs e)
           {
               base.OnStartup(e);
   
               // Set the access token for ArcGIS Maps SDK for .NET.
               Esri.ArcGISRuntime.ArcGISRuntimeEnvironment.ApiKey = "YOUR_ACCESS_TOKEN";
   
               // Call a function to set up the AuthenticationManager for OAuth.
               UserAuth.ArcGISLoginPrompt.RegisterOAuthConfig();
   
           }

3. Remove the code that sets up user authentication.

   App.xaml.cs

           protected override void OnStartup(StartupEventArgs e)
           {
               base.OnStartup(e);
