In our last post in this series, we discussed the importance of first learning how ArcGIS Pro works when approaching the Pro SDK. When you first understand how you can use Pro in a general way, you’ll be making better decisions about how you can best extend Pro. If you’re coming from years of working with ArcMap, this will be even more important and practical, so as to not make any design assumptions you might need to change later. In addition to the online resources, there are a number of introductory ArcGIS Pro books out there now, including some from Esri Press, along with other training options such as introductory courses.
Update February 2018:
As mentioned in the last post, we know making the move to a new SDK can be challenging, and we want to help you find the resources you need quickly and easily to make good progress with the Pro SDK – this includes comprehensive documentation and educational resources. Currently, all of the SDK resources are available online and available for you to get started with, we'll describe all these below. Also, with regard to formal training, Esri Educational Services is currently working on a new instructor-led training course on the Pro SDK which we're happy to announce will be available later this year. As with our other instructor-led courses, it will be available online as well. The course will provide an excellent introduction to the Pro SDK for developers. We’ll be keeping you informed on this news and we’ll have a post when the course is available.
The Online Resources
So, after getting equipped with a good understanding of Pro and your potential new Pro workflows, you’re ready to start exploring the Pro SDK in detail. There is a wealth of SDK learning resources to help you get going right from the Pro SDK landing page.
Whether you’re an experienced ArcObjects developer, or entirely new to GIS development, there is documentation available to help you get started. Let’s walk through all of these common resource links:
In general, spending some time checking out each of the above sites can really help you to familiarize yourself with the content and on how to get around. One important note on the SDK community samples – these are free and ready to be integrated into your own solutions. They’re a key important resource for understanding the concepts and stepping through code as you look to try out the many capabilities in Pro. There is a helpful guide on how to begin to use them found here. Also, don’t forget to download the accompanying sample dataset for use with the samples which is located here – https://github.com/Esri/arcgis-pro-sdk-community-samples/releases You’ll see these sample projects and datasets referred to in the walk-through’s for each of the samples.
For working with the samples, remember that the free Visual Studio Community edition, both 2013 and 2015, work with the Pro SDK. Also, if you’re in need of a free trial of ArcGIS for Desktop to get started with Pro, you can register for a 60-day trial here.
For online training video resources, this recent post provides links to each of the most recent videos available this year. Two key resources were mentioned:
All of these videos can help you to understand different aspects of programming with the Pro SDK, such as the main patterns, design, and help you to understand the different functional areas of the Pro API.
Big Picture Concepts
One of the key features of the Pro SDK as mentioned before is asynchronous development. This pattern is still new for many GIS developers. It’s an important place to get started in learning the capabilities of Pro, and how you can keep the UI responsive, building a great user experience. The videos mentioned above provide some introductions to the pattern, like this Dev Summit presentation on programming patterns and the Pro SDK LTS. There are some resources on the Pro SDK wiki, as well, like this concept page, the second-half of which is dedicated to working with multithreading in Pro. Also, Microsoft has a number of resources including this article on asynchronous programming which has samples and additional links.
As with all of these new concepts, take a look at the community samples and see how things are done with the different Pro API functional areas. Also, take a good look at the different SDK templates that are available, and learn how and when to use each, one of the best ways to do this is to go through each of the ProGuide docs under the “Framework – Customization” topic found on the margin of the SDK wiki page, as seen here to the right.
The Pro SDK uses the add-in extensibility model first introduced with ArcGIS Desktop 10.0. As with traditional 10.x add-ins, the Pro SDK add-in UI components are defined within an XML file, and for the Pro SDK the filename is Config.daml, the .daml extension is for Desktop Application Markup Language (DAML). In the Config.daml you declare the buttons, tools, menus, dockpanes, tabs, etc. that your add-in contains and will be used to customize the Pro UI. Most of these classes will then have their respective data and logic components implemented in a separate file. For the most part, however, you can use one of the ArcGIS Pro SDK item templates to automate the DAML updates as well as adding the code behind files.
ArcGIS Pro SDK also takes advantage of Windows Presentation Foundation (WPF), Model-View-ViewModel (MVVM), and XAML. MVVM is a popular design pattern for XAML-based development and helps you to separate the UI components of your add-in from the data and logic components. Use MVVM in Pro to define custom content for your add-in dockpanes, dialogs, property sheets, and embedded controls. You can use the ArcGIS Pro SDK item templates to generate much of the required boiler plate code for the MVVM pattern. A good introduction is provided in this Microsoft doc, which describes how MVVM makes applications easier to test, maintain, and improves code re-use opportunities. There are other good sources of information on the MVVM pattern on the web, and the ProConcept Framework doc provides some important considerations for the SDK.
Get Started, Get Creative
We’ve seen some great work being done by different organizations this year with the Pro SDK. Some are getting creative on how they approach the new material, which is always impressive. One of the ways we’ve seen some large GIS development teams get started is by putting together their own internal Pro SDK workshops and hackathons.
From what we’ve seen, including organizations that manage large ArcObjects codebases, these can lead to focused and faster learning, providing the opportunity to quickly become familiar with and try out the Pro SDK. Some aspects of successful hackathon efforts we’ve seen:
Overall, these types of learning exercises can help you and your team ramp up more quickly on the SDK and its scope, and help the whole organization to begin to define next steps and plans for extending Pro.
Your team may already be well-versed with these practices and have other ideas for fast-tracking your development learning. We encourage you to get started soon with the SDK. As always, it helps to try and get a simple add-in rolling and then build on it. Another note on scope, the sooner you can get started actively working with the SDK, the sooner you determine whether a capability you require in the Pro API is available for all the workflows you design. As mentioned in our last post, this we’re growing the Pro SDK based on user requirements, and the sooner we receive your input, the sooner we’ll be able to try and plan and prioritize efforts to address those needs in growing the SDK.
Bottom Line: There is a comprehensive set of online resources available to help you learn the Pro SDK, and lots of ways your development team can creatively move ahead together and make great strides with it. We know the Pro SDK is a big step for many Desktop developers, it’s definitely not ArcObjects… it’s new, it’s different, and lighter-weight. The many features of Pro and the Pro SDK will hopefully make it an exciting and interesting learning experience which you’ll enjoy. We want you to be successful with both Pro and the Pro SDK.
So what other resources would you like to see offered which might help you with the Pro SDK?
