Book this course

Part 1: Remote SharePoint development

Introduction to SharePoint and Office 365 development

Office 365 delivers Software as a Service (SaaS). It provides multiple services that a customer can chose from like Exchange Online, SharePoint Online, OneDrive for Business, … This module will give you a developer's overview on Office 365 and SharePoint.

  • Office 365 services: SharePoint Online, Exchange Online, Skype for Business...
  • SharePoint 2013 vs SharePoint 2016 vs SharePoint Online development options
  • Development environment and options

Client side development using CSOM

This module will introduce you to client side development in .NET using the Client Side Object Model (CSOM), a library that makes your life easier when communicating with SharePoint.

  • Getting started with CSOM
  • Authentication with CSOM
  • Consuming SharePoint
  • Code efficiency with CSOM
  • Additional libraries in CSOM
  • Administering your tenant with CSOM


Next to a nice library, like CSOM, SharePoint also provides REST/OData endpoints to communicate with. These endpoints support the same operations as CSOM does. One of the advantages of using the REST/OData APIs is that you are not tied to using .NET as a development language. You are free to chose whatever language you want, as long as it can make calls to a webservice.

  • Getting started with the REST APIs
  • Authentication with REST APIs
  • OData querying syntax
  • Batch processing
  • The need for digest tokens

JavaScript Client Side Development

Using the client-side development approach, you can also consider JavaScript. In fact, if you want to build components that can be hosted inside your SharePoint sites, JavaScript is currently the best option. When using JavaScript, you have several options to choose from. This module will introduce you to the different options you have using JavaScript.

  • JavaScript embedding options
  • JavaScript Object Model (JSOM) library
  • Using the REST APIs
  • Cross-domain library
  • PnPJS library

Part 2: SharePoint Add-ins

Introduction to SharePoint Add-ins

The SharePoint add-in model does not allow you to run custom server site code on SharePoint; custom code has to be executed remotely. The add-in model provides two hosting options that you can choose from: SharePoint hosted or Provider hosted. SharePoint hosted add-ins are entirely hosted in SharePoint and developers are restricted to code that runs in the browser. Provider hosted add-ins are hosted outside SharePoint and developers are not restricted in their choice of technology. This module will illustrate the fundamentals of building SharePoint and Provider hosted add-ins.

  • SharePoint add-in hosting options
  • Visual Studio Project Templates
  • The anatomy of the project
  • SharePoint Add-in Package
  • Declaritively provisioning artifacts
  • Custom Actions & Add-in parts

SharePoint add-in Authentication

The SharePoint add-in model introduced a new way of thinking about security. SharePoint authenticates and authorizes components, developed according to the add-in model, using the OAuth 2.0 protocol. This module will explain you the details of the OAuth protocol and will explain you the differences between OAuth and the Server to Server Authentication used in on-premises farms.

  • User versus add-in authentication in SharePoint
  • OAuth 2.0 and the SharePoint authentication flow: Context Tokens, Refresh Tokens and Access Tokens
  • Server to Server High Trust Authentication
  • Requesting and granting permissions
  • Delegated versus app-only authentication

Deploying your SharePoint Add-ins

Once an add-in is completely developed, tested and approved, it is time to publish it. This module will discuss what you have to take into account when deploying your SharePoint add-in.

  • Application registration
  • Corporate App Catalog
  • Client IDs and Client Secrets
  • Publishing the remote parts
  • Publishing the SharePoint add-in package

Part 3: SharePoint development extras

Office UI Fabric

Making sure your applications share the same look and feel as SharePoint Online can be a challenge. Luckily there is a UI framework, called Office UI Fabric, that can help you to apply the same look and feel, as in SharePoint, to your application.

  • Branding your applications with Office UI Fabric
  • Office UI Fabric styles
  • Office UI Fabric components

Introduction to PnP

Since the introduction of the SharePoint Add-in model, it has sometimes become difficult to translate your old code to this new model. Because of this, Microsoft took the initiative to start SharePoint Patterns and Practices (PnP), offering techniques and solutions on how to tackle certain problems when transforming your solutions to the add-in model. Today, SharePoint PnP has grown so much that it now offers techniques, reusable and demo solutions on SharePoint and Office 365 development.

  • What is PnP and how can it help me?
  • Using the PnP.Core in your applications
  • Simplifying authentication using the PnP IdentityModel
  • Reusable solutions for SharePoint On-Prem and Online with the Partner Pack
  • Using the PnP PowerShell CmdLets

Remote Provisioning

When developing SharePoint customizations, often you will need to deploy new sites, lists, contenttypes, themes, files, ... . This process is referred to as Provisioning SharePoint Artifacts. With the remote development model, this now becomes Remote Provisioning.

  • Why do we need (remote) provisioning?
  • Using JSON site design
  • PnP provisioning engine

SharePoint Webhooks

SharePoint allows you to subscribe to events that happen within lists and get notified asynchronously when those events happen.

  • How to handle webhook subscriptions and event notifications
  • SharePoint Webhooks
  • Debugging Webhooks

Introduction to SharePoint Framework

In this module, participants will get introduced to the SharePoint Framework and where it fits into the SharePoint development options you have. This model is not a replacement for the add-in model, it can perfectly be used next to the add-in model.

  • SharePoint Framework overview
  • SharePoint Framework tools
  • Client Web Parts

Part 4: Office 365 development

Microsoft Identity Platform

With Microsoft Identity Platform, Azure Active Directory for developers, authentication has been simplified for developers by providing identity as a service, using industry-standard protocols like OAuth 2.0 and OpenID Connect. Participants will learn about user authentication in Azure AD, how to register applications and how to authenticate applications depending on the application type.

  • Microsoft Identity Platform overview
  • App Registrations
  • OAuth authentication flows
  • User authentication with Microsoft Identity Platform
  • Application authentication with Microsoft Identity Platform
  • Microsoft Authentication Libraries (MSAL)

Using Azure AD for SharePoint authentication

Remote code that wants to talk to the SharePoint webservices will have to pass by authentication. If the code was installed by means of an add-in, then add-in authentication could be applied. If there is no related add-in, then Azure AD can be used to retrieve access token in order to communicate with SharePoint.

  • Azure AD app registration for SharePoint
  • Delegated versus app-only authentication

Microsoft Graph

Office 365 provides you with one single endpoint allowing you to communicate with all Office 365 services. This API is known as the Microsoft Graph and allows developers to access data, intelligence and insights coming from the Microsoft cloud.

  • Microsoft Graph API
  • Discovering the different APIs: Mail, Contacts, Calendar, People, Mail...
  • Microsoft Graph SDK
  • Graph webhooks
  • Extending the Graph with extensions

Apps for Microsoft Teams

Since its introduction, Microsoft Teams has gained popularity in the workplace as the number one chat-based collaboration platform. Developers can extend Teams with their own customizations, like tabs, bots, ... . This module will introduce you to Teams Development.

  • Introduction to Teams development
  • Using App Studio
  • Apps for Teams capabilities
  • Using the Teams SDK

Azure Utilities

Azure comes with a lot of features that can help you when developing against Office 365. In this module, participants will learn which features from Azure can help them building their Office 365 customizations.

  • Using the Azure Queue
  • Delegate functionalities to Azure functions
  • Using Logic Apps

With the introduction of apps, back in SharePoint 2013, Microsoft introduced a new development model where the main focus is to develop any customizations outside of SharePoint. Whether this is done by writing your applications and hosting them on an other server, or done by using client side technologies like JavaScript is up to you. Since the introduction in 2013, this way of working is starting to become the standard for SharePoint and Office 365 customizations. This extensive training will teach you what options you have when building your SharePoint and Office 365 applications or components.

This training is targeted at developers that want to start using this new development model in their customizations for SharePoint and Office 365. No prior development knowledge on SharePoint is required. Being familiar with .NET and JavaScript is advised, as well as having user-experience with SharePoint.
The training is also targeted at existing SharePoint developers that have been using the Solution development approach and now want to get started with this new model.
