Build SDKs for .NET

Required tools

Target project requirements

Before you can compile and run the generated files, you will need to make sure they are part of a project with the required dependencies. After creating a new project, or reusing an existing one, you will need to add references to the abstraction, authentication, http, and JSON and text serialization packages from the GitHub feed.

Creating target projects

Note: you can use an existing project if you have one, in that case, you can skip the following section.

Execute the following command in the directory you want to create a new project.

dotnet new console -o GetUserClient
dotnet new gitignore

Note: in this example the console template is used, but you can use any C# template.

Adding dependencies

dotnet add package Microsoft.Kiota.Abstractions --prerelease
dotnet add package Microsoft.Kiota.Http.HttpClientLibrary --prerelease
dotnet add package Microsoft.Kiota.Serialization.Json --prerelease
dotnet add package Microsoft.Kiota.Serialization.Text --prerelease
dotnet add package Microsoft.Kiota.Authentication.Azure --prerelease
dotnet add package Azure.Identity

Only the first package, Microsoft.Kiota.Abstractions is required. The other packages provide default implementations that you can choose to replace with your own implementations if you wish.

Generating the SDK

Kiota generates SDKs from OpenAPI documents. Create a file named getme.yml and add the contents of the Sample OpenAPI description.

You can then use the Kiota command line tool to generate the SDK classes.

kiota -d getme.yml -c GetUserApiClient -n GetUserClient.ApiClient -o ./Client

Creating an application registration

Note: this step is required if your client will be calling APIs that are protected by the Microsoft Identity Platform like Microsoft Graph.

Follow the instructions in Register an application for Microsoft identity platform authentication to get an application ID (also know as a client ID).

Creating the client application

The final step is to update the Program.cs file that was generated as part of the console application to include the code below. Replace YOUR_CLIENT_ID with the client ID from your app registration.

using Azure.Identity;
using GetUserClient.ApiClient;
using Microsoft.Kiota.Authentication.Azure;
using Microsoft.Kiota.Http.HttpClientLibrary;

var clientId = "YOUR_CLIENT_ID";

// The auth provider will only authorize requests to
// the allowed hosts, in this case Microsoft Graph
var allowedHosts = new [] { "" };
var graphScopes = new [] { "User.Read" };

var credential = new DeviceCodeCredential((code, cancellation) =>
    return Task.FromResult(0);

var authProvider = new AzureIdentityAuthenticationProvider(credential, allowedHosts, graphScopes);
var requestAdapter = new HttpClientRequestAdapter(authProvider);
var client = new GetUserApiClient(requestAdapter);

var me = await client.Me.GetAsync();
Console.WriteLine($"Hello {me.DisplayName}, your ID is {me.Id}");


  • If the target API doesn’t require any authentication, you can use the AnonymousAuthenticationProvider instead.
  • If the target API requires an Authorization bearer <token> header but doesn’t rely on the Microsoft identity platform, you can implement your own authentication provider by inheriting from BaseBearerTokenAuthenticationProvider.
  • If the target API requires any other form of authentication schemes, you can implement the IAuthenticationProvider interface.

Executing the application

When ready to execute the application, execute the following command in your project directory.

dotnet run
