How to fix differences on call Microsoft.Graph.Calendar between .NET Core and .NET Framework

问题

I have a strange problem with conversion from .NET Core 3.1 to .NET Framework 4.7.2. It should be compatible in base area, but not always.

var calendars = _graphClient.Users[$"{userId}"].Calendars.Request().GetAsync().Result;

This function work fine in .Net Core, but not in .Net Framework makes error with following exception:

NotSupportedException: The collection type 'Microsoft.Graph.IUserCalendarsCollectionPage' is abstract, an interface, or is read only, and could not be instantiated and populated. The unsupported member type is located on type 'System.Collections.Generic.List`1[Microsoft.Graph.Calendar]'. Path: $.value | LineNumber: 0 | BytePositionInLine: 123.

Have you any idea how fix it?
