Ron,

If you want to use the following .NET Framwork types in VB.Net then you are out of luck:-

System.Sbyte
System.UInt16
System.UInt32
System.UInt64

Also C# supports the use of unmanaged code which VB.Net does not, this can and does prove to be a useful feature. If you look at it the other way round then VB.Net still maintains certain features for compatibility like non-structured error handling in C# you only get SEH.

HTH
