.Net and 64-bit

Is .Net aware of 32-bit/64-bit processor/Windows version at all?

How to check if a system 32-bit processor or 64-bit Windows? I looked at
"Control Panel/System" icon of a 2003 Server version, but it didn't show
anything about these?

MSIL is not but CLR is.

You could check if IntPtr.Size returns 4 or 8.

..NET code compiles to byte code, so it does not have to be aware of a
certain type of CPU if you are not natively generating (ngen.exe). The
framework is, at the core, set up for a particular environment (32 or 64),
but this means Framework 2.0 as 3.0 and 3.5 sit on top of it.

Yes. The JIT compiler will compile the code for the processor that it
runs on, so on a 64 bit system you get 64 bit native code.

If it's a 32 bit system, it doesn't say anything about it, but if it's a
64 bit system, it says for example:

Microsoft Windows Server 2003
Standard x64 Edition
Service Pack 2

Start button, right click Computer, Properties. It tells you if it is Win32
or Win64.

Well, not exactly. The version of Windows that the OP has doesn't tell
you if it's a 32 bit system, but it tells you if it's a 64 bit system.
So if it doesn't specify either, it's a 32 bit system.
