ArcGIS Pro 3.7 SDK for .NET
ArcGIS Pro Version: 3.7.0.1901
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.

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:

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
ArcGIS Pro Gdal NuGet
GDAL is a translator library for raster geospatial data formats that is released under an X/MIT style Open Source license by the Open Source Geospatial Foundation. This Nuget is specifically created for interfacing with GDAL within ArcGIS Pro. This Nuget uses Gdal version 3.11.3.
Starting at 3.6, developers wanting to use GDAL in their addins can use the Esri.ArcGISPro.Gdal Nuget. Binding against the appropriate Esri.ArcGISPro.Gdal Nuget ensures your addin will be compatible with the underlying Gdal version in use by ArcGIS Pro.
- Esri.ArcGISPro.Gdal.3.6.0.nupkg: Gdal version for 3.6: 3.11.3, .NET 8
- Esri.ArcGISPro.Gdal.3.7.0.nupkg: Gdal version for 3.7: 3.12.2, .NET 10

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:
ArcGIS Pro 3.3.3 and 3.4.1 Patches
AllSource 1.2 and 1.3 users:
For users installing both the ArcGIS Pro and AllSource patches (whether 3.3.3 and 1.2.1 or 3.4.1 and 1.3.1) you may encounter an issue with the RegisterAddin.exe file association for .esriAddinX and .proConfigX files being broken. Please refer to this KB article for more information: Restore RegisterAddin.exe file association for ArcGS Pro SDK Addins and Configurations
ArcGIS Pro Extensions NuGet Users:
If you are using ArcGIS Pro Extensions NuGet with ArcGIS Pro 3.3 or 3.4, and you install the ArcGIS Pro 3.3.3 or 3.4.1 patch you may encounter an issue where the addin or configuration is no longer registered to the default well-known folder during compilation. This will affect your ability to debug your addins and configurations. To fix this issue, please upgrade your Esri.ArcGISPro.Extensions30 NuGet to either of Esri.ArcGISPro.Extensions30 3.3.3 or 3.4.1 depending on your ArcGIS Pro release.
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 3.7 SDK (or 3.0 SDK) from 2.x is not an upgrade. To install,
- Consult Migrating from 2.x if you want to install ArcGIS Pro 3.7 SDK and you are on 2.x, not 3.x.
- If you are migrating a 2.x add-in to 3.7 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 10 Upgrade for more details.
Read the ProGuide: Installation and Upgrade for detailed installation instructions.

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:
| 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
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.
