ArcGIS Pro 3.3 SDK for .NET

ArcGIS Pro Version: 3.3.0.52636

Extend ArcGIS Pro with the ArcGIS Pro SDK for Microsoft .NET. The ArcGIS Pro SDK provides four main extensibility patterns: add-ins, managed configurations, plugin datasources and CoreHost applications. You can leverage modern .NET features and patterns such as Task Asynchronous Programming (TAP), LINQ, WPF Binding, and MVVM to build integrated 2D and 3D add-ins with the ArcGIS Pro APIs.


In this topic

Overview of the ArcGIS Pro SDK

  • Add-in developers can use the new WebViewBrowser control based on Microsoft Edge WebView2. Microsoft Edge WebView2 Runtime version 117 or later is required.

ArcGIS Pro system requirements

ArcGIS Pro API

The ArcGIS Pro APIs are managed .NET assemblies which are installed with each ArcGIS Pro installation. Intermediary assemblies containing .NET metadata or PIAs (Primary Interop Assemblies) are not required.

Add any of the ArcGIS Pro managed assemblies that comprise its API as references directly in your Visual Studio add-in projects.

A complete list of the ArcGIS Pro assemblies in the public API is provided below. Consult the online API Reference for specific details of each assembly:

Core

Core assemblies are located in the {ArcGIS Pro Installation folder}\bin.

Assembly Description
ArcGIS.Core.dll Provides CIM, Geodatabase, Geometry and Utility Network APIs.
ArcGIS.CoreHost.dll Provides Host.Initialize to initialize ArcGIS.Core.dll for stand-alone use.
ArcGIS.Desktop.Framework.dll Provides the application framework to include add-in contracts, DAML support, and base classes. This assembly must be referenced by every add-in.
ESRI.ArcGIS.ItemIndex.dll Provides functionality to create and work with Custom items.

Extensions

Major subsystems within ArcGIS Pro are organized into units called extensions. Extension assemblies are located in the {ArcGIS Pro Installation folder}\bin\Extensions folder in their own individual subfolder. Extension subfolder names are logically named for the unit of functionality they represent, for example, Mapping, Editing, Layout, and so on.

Assembly Description
ArcGIS.Desktop.Catalog.dll Provides access to project content items (map items, layout items, style items, folder items, and so on).
ArcGIS.Desktop.Core.dll Provides functionality to create and manage projects, access to events associated with the current project, and the ability to execute geoprocessing tools.
ArcGIS.Desktop.DataReviewer.dll Provides functionality to establish and manage Reviewer results, sessions, and batch jobs in a project.
ArcGIS.Desktop.Editing.dll Provides access to the editing environment and core editing functionality required for custom edit tool implementations.
ArcGIS.Desktop.Extensions.dll Provides extension methods for other ArcGIS Pro classes. Provides a base class for custom map tools.
ArcGIS.Desktop.Geoprocessing.dll Provides access to geoprocessing history items stored in the project. (Note: Adds a reference to ArcGIS.Desktop.Core.dll to execute geoprocessing tools.)
ArcGIS.Desktop.KnowledgeGraph.dll Provides access to KnowledgeGraphs in maps and link charts.
ArcGIS.Desktop.Layouts.dll Provides functionality for manipulating elements on a layout and exporting to a variety of image formats.
ArcGIS.Desktop.Mapping.dll Provides types to create maps and layers, label features, perform query operations, and visualize them in 2D or 3D. Provides a raster API to create raster layers and customize raster rendering, and an API to manage styles, style items, and symbols.

ArcGIS Pro Extensions NuGet

The ArcGIS Pro Extensions NuGet contains all the Pro API assemblies needed to compile your Add-ins and Configurations and offers an alternate way to reference the ArcGIS Pro assemblies in your add-in and configuration over traditional file based references.

To use the ArcGIS Pro Extensions NuGet, set the NuGet Package Management format setting in Visual Studio to be PackageReference.

ProGuide: ArcGIS Pro Extensions NuGet

2. SDK Resources

There are many ProConcepts, ProGuide, ProSnippets, and samples to help you get up and running with the new SDK features. Updates to the SDK Resources include, but are not limited to:

Installing ArcGIS Pro SDK for .NET

ArcGIS Pro SDK for .NET can be downloaded and installed from within Visual Studio. There will be 2 separate extensions you can install:

  • ArcGIS Pro SDK for .NET,
  • ArcGIS Pro SDK for .NET (Utilities)

Notes: Moving to ArcGIS Pro 3.3 SDK (or 3.0 SDK) from 2.x is not an upgrade. To install,

  1. Consult Migrating from 2.x if you want to install ArcGIS Pro 3.3 SDK and you are on 2.x, not 3.x.
  2. If you are migrating a 2.x add-in to 3.3 you can install the migration tool to help automate the conversion process. Moving from 2.x to 3.x is a breaking change. Refer to the migration guide ProConcepts: 3.0 Migration Guide and ProGuide:.NET 8 Upgrade for more details.

Read the ProGuide: Installation and Upgrade for detailed installation instructions.

In general, there is a one-to-one correspondence between a framework UI element extensibility point (e.g. button, tool, menu, dockpane, etc) and an item template. Use the relevant item template to add the corresponding extensibility point to your Add-in.

ArcGIS Pro SDK for .NET utilities

Package: proapp-sdk-utilities.vsix

ArcGIS Pro SDK for .NET (Utilities) provides the following utilities that extend the Visual Studio environment:

pro-fix-references

Name Description
Pro Fix References utility Fixes broken references in an ArcGIS Pro add-in, core host, configuration, or plug-in projects. Broken references can be caused when you share add-ins with other colleagues or download add-ins where the ArcGIS Pro assembly references point to a different location from where you installed them. Pro Fix References can be run on individual projects or all projects within a solution.
Pro Generate DAML Ids utility Converts all of the ArcGIS Pro Desktop Application Markup Language (DAML) string IDs into static string properties organized by DAML element types (for example, Button, Dockpane, Tool, Condition, and so on). This allows you to use the IntelliSense feature of Visual Studio within your source code file to add IDs, rather than having to manually type DAML string IDs).

ArcGIS Pro SDK for .NET Migration

Package: proapp-sdk-migration.vsix

pro-migration

ArcGIS Pro SDK for .NET (Migration) provides support to migrate ArcGIS Pro SDK 2.x extensions to ArcGIS Pro SDK 3.x for .NET. Note: When you migrate your add-in, the dekstopVersion attribute in your config.daml will be set to the current version of ArcGIS Pro installed.

Previous versions

Resources

All the above Pro SDK icons are available as XAML resources in ArcGIS.Desktop.Resources.dll. In your addin Config.daml, you can reference the Pro SDK Icons directly from ArcGIS.Desktop.Resources.dll to use as the image for your controls on the Pro Ribbon. The code snippet below provides the syntax to be used in your add-in's config.daml. Note: the string "BexDog32" can be replaced by any of the image names listed in the Pro SDK icon images above.

<button...smallImage="BexDog16" largeImage="BexDog32"/>

You can also access these resources as an ImageSource in your WPF code-behind. In the following code snippet, the BexDog32 Pro SDK icon is being accessed as the ImageSource for the return value of an ImageSource property in a view model. Note: the string "BexDog32" can be replaced by any of the image names listed in the icon image above.

  public ImageSource SomeCustomProperty {
    get {
       return Application.Current.Resources["BexDog32"] as ImageSource;
    ...
