About 2 years ago, and as recently as perhaps 1 year ago, I can recall
seeing many posts about what language to use with ASP.Net. The consensus was
that employers paid more for C# programmers, and it seems that C# became the
darling of the ASP.Net crowd.
In the meantime, I have observed an interesting phenomenon. Originally,
employers hired programmers who used C# because it was based on C, and the
prevailing opinion was (and may still be) that C# developers were better
because they must have known and/or practiced C or C++ at some time, which
would make them better programmers overall. C and C++ are hard-core
programming languages compared to VB.
However, now that nearly everyone has jumped on the C# bandwagon, it seems
to me that the distinction between the languages has nearly disappeared, at
least in terms of evaluating programmers for hire. There seem to be almost
as many clueless C# developers out there as VB.Net developers. Many C#
developers today are basically VB.Net developers using a different syntax. I
wonder if the employers have become aware of this trend?

What about VarPtr, VarPtrArray, StrPtr, and ObjPtr? Won't they still work in
VB.Net?

I'm afraid that's simply untrue. You can't use unmanaged code in VB,
pointers, and several other less important items. Yes, it may be a rare
occasion that you need to, but believe it or not, I've worked on several
projects over the past year which process very large (200 - 500 MB)
images,
and there's no substitute for pointers in a situation like that. In fact,
even with the use of pointers, I have one app that takes several hours to
process a single image.

Those are not available in VB.Net. The closest you can get to a pointer in
VB.Net is a delegate.

I have to amend my remarks: There are several other ways to obtain
"pointers" in VB.Net, but again, you don't get the raw functionality of a
true pointer using any of them. The most common is the IntPtr, and there are
also some undocumented versions of a couple of the types you mentioned. You
can read about them here: http://www.codeproject.com/vb/net/Marshal.asp
Again, though, I would stress that you cannot do with them what you can do
with unmanaged pointers, which is accessing and manipulating memory
directly.
