Visual D showing weird errors

Hello, I'm new to the language; I just started learning it a few
months ago. I'm doing okay with it, I find it very versatile and
fast to learn. I come from Java and C/C++ and I think D solves
tons of problems I had with these.
I was trying the Visual D extension to Visual Studio, but after
the first code generation (DLL library, x86 & x64 both checked),
I get this weird error:
```
C:\D\dmd2\src\druntime\import\core\sys\windows\dll.d:
\object.d(18): can only `*` a pointer, not a `typeof(null)`
```
So I opened the object.d in VS and apparently, this is the line
of code it's yelling at:
```
alias noreturn = typeof(*null); /// bottom type
```
I am unsure how to solve this problem. It doesn't appear to
happen if I choose "console application" instead of "DLL Library".
Although, errors do appear if I try to inspect, for example,
stdio.d:
```
Error: C:\D\dmd2\src\druntime\import\object.d(3460): template
instance `object._dup!(const(char), immutable(char))` error
instantiating
C:\D\dmd2\src\druntime\import\object.d(3438): instantiated from
here: `_trustedDup!(const(char), immutable(char))`
C:\D\dmd2\src\phobos\std\exception.d(516): instantiated from
here: `idup!(const(char))`
C:\D\dmd2\src\phobos\std\exception.d(437): instantiated from
here: `bailOut!(Exception)`
--> instantiated from here: `enforce!(void*)`
```
and also:
```
Error: C:\D\dmd2\src\phobos\std\exception.d(437): template
instance `std.exception.bailOut!(ErrnoException)` error
instantiating
--> instantiated from here: `enforce!(shared(_iobuf)*)`
```
and others.
Since these are thrown by the standard library, I suspect this
could be a bug; but maybe I'm just missing something?
Thank you for your help.
