Microsoft Graph .NET SDK v5 is now generally available 

Maisa Rissi

The Microsoft Graph .NET SDK v5, now generally available (GA), allows you to take advantage of a fluent API and models that support retry handling, secure redirects, batching requests, large file management, and many more capabilities. Focus on what really matters, your business.  

Along with all the features and improvements highlighted in the v5 release candidate announcement, such OData cast support and backing store, this GA release delivers a small change described below. 

OData cast now provides shorter names 

Because OData cast allows downcasting the result to the right specialized type, v5 users now have access to all properties in the response, rather than pulling those out from the AdditionalData. To not require users to use the fully qualified name as a code path to cast, the OData cast was simplified to provide the shortest name possible when still avoiding collisions.

For those using v5 preview versions, the OData cast was shortened from MicrosoftGraph<Entity> to Graph<Entity>. In the example above, it changed from MicrosoftGraphUser to GraphUser. 

Methods doesn’t require full namespaces 

As a similar approach to the OData cast, users now don’t need to specify the MicrosoftGraph namespace as part of the method. This change simplifies the fluentAPI by keeping only the method name as part of the method chaining.

For those using previews versions of v5, the method was shortened from MicrosoftGraph<Method> to only <Method>, given the example above, it changed from MicrosoftGraphSendMail to SendMail.

    Any ASP.NET Core example, targeting this new SDK? Specifically the authentication? I had problem with .AddMicrosoftGraph() which wasn’t working with this version because it was targeting different version of Microsoft.Graph.Core.

    Where is the production version of the documentation for the Kiota v5 API set? Where can I find the following documentation for the following APIs:

    //Fetching the members of a group who are of the type User
    var usersInGroup = await graphServiceClient

    List userList = usersInGroup.Value;

    //Similarly, members of the group of type ServicePrincipal
    var servicePrincipalsInGroup = await graphServiceClient

    List servicePrincipalList = servicePrincipalsInGroup.Value;
