Actually, netapp-manageability-sdk-4.1-dotnet-bindings.zip is not a wrong package. It's just a different package containing different interfaces to connect to NetApp storage system.
It contains only the C# sample codes. If you want to use only the dotnet-bindings package for VB.NET, we can write sample codes for you and post it here. However, if you want to
use the regular SDK package (netapp-manageability-sdk-4.1.zip), you can get the VB.NET sample codes from the location mentioned in the previous post.
