What's new for developers at 10.4


Summary
This topic provides an overview of the new features and enhancements at ArcGIS 10.4 for developers working with the .NET API for ArcObjects.

In this topic

  • Supported platforms
    • Visual Studio
    • .NET Framework
  • Server Object Interceptor Chaining
  • Type changes

Supported platforms

The following subsections highlight development and deployment platform support changes for ArcGIS 10.4. For complete information on supported platforms, along with hardware and software requirements, see System Requirements.

Visual Studio

At ArcGIS 10.4, .NET development using Community, Professional, and Enterprise editions of Visual Studio 2013 or 2015 is supported.

.NET Framework

.NET 4.5 is a minimum requirement for any .NET development with ArcGIS 10.4. In fact, it is a prerequisite for installing ArcGIS for Desktop and ArcGIS Engine for Windows. Desktop ArcObjects SDK for 10.3.1 was the last release of the Desktop SDK to ship with support for .NET 3.5 Framework.
At 10.4, the Desktop ArcObjects SDK ships with .NET Framework 4.5 as the default. The 10.4 Desktop ArcObjects SDK will install PIAs built against .Net Runtime 4.0 and all new extension development should be started on NET Framework 4.5 or later.

Server Object Interceptor Chaining

Server Object Interceptor (SOI) chaining allows you to chain multiple SOIs together for a map or image service. This means that now you can complete more than one task at a time on a single service. When adding the SOIs to a service, you can specify the order in which the tasks will be executed. By default, SOIs that were developed at earlier releases will not support SOI chaining. You will need to edit your SOIs in order to chain them together.
To enable SOI chaining for existing SOIs follow these steps:
  1. Comment out the ‘Utility Code’ region
  2. At the top, add ‘using ESRI.ArcGIS.SOESupport.SOI’ line
  3. Remove _extensionCache and _serverEnvironment class members, and add _restSOIHelper
  4. Initialize _restSOIHelper in the Init()
  5. Replace all calls to the FindRequestHandlerDelegate<> with the _restSOIhelper.FindRequestHandlerDelegate<>
  6. Compile
    1. If you encounter errors compiling, check to make sure the entire ‘Utility code’ region is commented out and that all _extensionCache and _serverEnvironment variables have been removed.
  7. Clean up and remove the commented out ‘Utility code’ region
Deprecation Announcement
10.4 is the last release for the following Visual Studio features in the ArcObjects SDK for .NET. These features will be deprecated at 10.4.1:
  • ArcGIS Toolbox Reference utility  ArcGIS Toolbox Reference dialog box
  • The ArcGIS Add Class Wizard will no longer stub out the Interface members at 10.4.1. Instead, right-click on the Interface within Visual Studio after the Add Class Wizard has completed its code generation and use the Visual Studio Implement Interface functionality. ArcGIS Add Class Wizard
.NET and VCPP Samples
Starting at 10.4, the .NET and VCPP samples will be available online for download from https://github.com/esri/arcobjects-sdk-community-samples
