Hi @Ritu Yadav , your codes are used in graph api version 4.x. You might downgrade your Graph SDK version. If you want to use Graph SDK V5.x, then there's no .Request() indeed, you can see the migration guide here. The Drive Item path also changed in SDK, you might search for Drive and see the details.

Creating nested folder should follow this section and the request should look like this.

using Microsoft.Graph.Models; 

var requestBody = new DriveItem { 
	Name = "New Folder", 
	Folder = new Folder { }, 
	AdditionalData = new Dictionary<string, object> { 	
		{ "@microsoft.graph.conflictBehavior" , "rename" }, 
	}, 
}; 
// To initialize your graphClient, see https://learn.microsoft.com/en-us/graph/sdks/create-client?from=snippets&tabs=csharp 
var result = await graphClient.Drives["{drive-id}"].Items["{driveItem-id}"].Children.PostAsync(requestBody);
