Microsoft Graph Toolkit: reusable web components to access M365 data

Hey there! In this article, Microsoft Graph Toolkit will be consumed in an ASP.NET Core MVC web app to enable:

  • Microsoft identity platform authentication
  • The agenda from Outlook Calendar
  • The tasks from Planner
  • E-mails from Outlook

If you never heard of Microsoft Graph Toolkit before, it is a powerful collection of reusable web components that enables accessing Microsoft 365 data with just couple lines of code! Believe it or not, Microsoft identity platform authentication can be implemented in seconds.

This web app will be a quick scenario to try out Microsoft Graph Toolkit!

ASPNET Core App

You can get the source code from here.

Create ASP.NET Core MVC web app in Visual Studio Code

  • Open the Terminal in Visual Studio Code (Ctrl+Shift+`)
  • Then, create a new folder for the project

PS C:\Users\user> cd Desktop
PS C:\Users\user\Desktop> mkdir GraphToolkitNetCore

  • Create ASP.NET Core MVC app

PS C:\Users\user\Desktop> dotnet new mvc
PS C:\Users\user\Desktop> cd GraphToolkitNetCore

  • The app is created successfully! Now, click on β€œOpen Folder” to open your project folder.

VSCode MVC App

  • Press F5 to run the project

Welcome Page

  • Our project is working fine. Before we start building our app with Microsoft Graph Toolkit, let’s go to Properties > launchSettings.json and set β€œhttp://localhost:8080” to applicationUrl

Localhost Setup

Register an app in Azure Active Directory

  • First thing first, go to Azure Portal!
  • Under Azure Active Directory, go to App Registration and click on New Registration

AAD New Registration

  • Give a name to your app
  • Choose the access level
  • Choose Web and place http://localhost:8080 as a Redirect URI

App Registration

  • Go to Authentication tab
  • Then, check Access tokens and ID tokens

Tokens

  • Finally, go to Overview tab
  • Copy Application (client) ID to a notepad, we will need it later

App ID

Setup Index.cshtml

  • Go to Index.cshtml and add a row and three columns inside the row
<div class="row" id="content">
     <div class="column" id="one"></div>
     <div class="column" id="two"></div>
     <div class="column" id="three"></div> 
</div>
~~~

* Copy below additional css to **site.css** under **wwwroot>site.css**

~~~css
/* Main content */
#content, html, body {
  height: 98%;
}
#one {
  float: left;
  width: 33%;
  background:transparent;
  height:500px;
  overflow: hidden;
}
#one:hover {
  overflow-y: auto;
}
#two {
  float: middle;
  width: 33%;
  background: transparent;
  height: 500px;
  overflow: hidden;
}
#two:hover {
  overflow-y: auto;
}
#three {
  float: left;
  width: 33%;
  background: transparent;
  height: 500px;
  overflow: hidden;
}
#three:hover {
  overflow-y: auto;
}
/*Email*/
.email {
  box-shadow: 0 3px 7px rgba(0, 0, 0, 0.3);
  padding: 10px;
  margin: 8px 4px;
  font-family: Segoe UI, Frutiger, Frutiger Linotype, Dejavu Sans, Helvetica Neue, Arial, sans-serif;
}
.email:hover {
  box-shadow: 0 3px 14px rgba(0, 0, 0, 0.3);
  padding: 10px;
  margin: 8px 4px;
}
.email h3 {
  font-size: 12px;
  margin-top: 4px;
}
.email h4 {
  font-size: 10px;
  margin-top: 0px;
  margin-bottom: 0px;
}
.email mgt-person {
  --font-size: 10px;
  --avatar-size-s: 12px;
}
.email .preview {
  font-size: 13px;
  text-overflow: ellipsis;
  word-wrap: break-word;
  overflow: hidden;
  max-height: 2.8em;
  line-height: 1.4em;
}
a.navbar-brand {
  white-space: normal;
  text-align: center;
  word-break: break-all;
}
