Error with Microsoft.Graph.User after upgrading Microsoft Graph Client Library

Hello, After updating the "Microsoft.Graph" version from 1.21.0 to 5.39.0 via the Nuget Package Manager in Visual Studio, I encountered the following error. How can this be fixed? CS0234:The type or namespace name 'User' does not exist in the namespace 'Microsoft.Graph' (are you missing an assembly reference?)

Microsoft Graph
Microsoft Graph

    Hi @Kenta Matsunaga,

    Version 1.21.0 uses Microsoft.Graph.Core 1.21.0 as dependencies, while version 5.39.0 uses Microsoft.Graph.Core 2.0.8 as dependencies. So the way they call will be different.

    In 5.39.0, there is no reference to Microsoft.Graph.User, just use using Microsoft.Graph;. Microsoft.Graph already includes User.

    For more detail, you can refer to the official documentation to Choose A Microsoft Graph Authentication Provider and Create requests.

    Hope this helps.
