Microsoft Graph .NET Core Client Library

Build Status NuGet Version

Integrate the Microsoft Graph API into your .NET project!

The Microsoft Graph .NET Core Client Library contains core classes and interfaces used by Microsoft.Graph Client Library to send native HTTP requests to Microsoft Graph API. The core client library targets .NetStandard 1.1 and .Net Framework 4.5.

Installation via NuGet

To install the client library via NuGet:

  • Search for Microsoft.Graph.Core in the NuGet Library, or
  • Type Install-Package Microsoft.Graph.Core into the Package Manager Console.

Getting started

1. Register your application

Register your application to use Microsoft Graph API by following the steps at Register your application with the Microsoft identity platform.

2. Authenticate for the Microsoft Graph service

The Microsoft Graph .NET Client Library supports the use of TokenCredential classes in the Azure.Identity library.

You can read more about available Credential classes here and examples on how to quickly setup TokenCredential instances can be found here.

The recommended library for authenticating against Microsoft Identity (Azure AD) is MSAL.

For an example of authenticating a UWP app using the V2 Authentication Endpoint, see the Microsoft Graph UWP Connect Library.

3. Create a HttpClient object with an authentication provider

You can create an instance of HttpClient that is pre-configured for making requests to Microsoft Graph APIs using GraphClientFactory.

HttpClient httpClient = GraphClientFactory.Create( version: "beta");

For more information on initializing a client instance, see the library overview

4. Make requests to the graph

Once you have an authenticated HttpClient, you can begin to make calls to the service. The requests to the service follows our REST API syntax.

For example, to retrieve a user's default drive:

HttpRequestMessage requestMessage = new HttpRequestMessage(HttpMethod.Get, "me/drive");
HttpResponseMessage response = await httpClient.SendAsync(requestMessage);
if (response.IsSuccessStatusCode)
{
    string jsonResponse = await response.Content.ReadAsStringAsync();
}

To get the current user's root folder of their default drive:

HttpRequestMessage requestMessage = new HttpRequestMessage(HttpMethod.Get, "me/drive/root");
HttpResponseMessage response = await httpClient.SendAsync(requestMessage);
if (response.IsSuccessStatusCode)
{
    string jsonResponse = await response.Content.ReadAsStringAsync();
}

Notes

Install System.Runtime.InteropServices.RuntimeInformation before you install Microsoft.Graph >=1.3 if you are having an issue updating the package for a Xamarin solution. You may need to updated references to Microsoft.NETCore.UniversalWindowsPlatform to >=5.2.2 as well.
