Hi!
I've been thinking about passing parameteras using references instead
of pointers in order to emphasize that the parameter must be an
object.
Exemple:

I'm reading the MS press C# book and there seems to be a contradiction.
Please tell me which one is correct, 1 or 2.
Thanks!

1. First it gives the code below saying that it prints 0 then 42.
They say that 42 is printed the second time since the value was wrapped in a
class and therefore became passed by reference.
(sorry for any typos I am a newbie here ;-)

I have a class Y in assembly B which is derived from a class Z in assembly
C. So I correctly add a reference to assembly C in assembly B, build
assembly B and everything builds fine. Now I create an assembly A which
refers to class Y in assembly B. So I add a reference in assembly A to
assembly B, and attempt to build. I get an error message, C3264, saying that
it could not find the type Z, and that it is in assembly C to which I have

I used WSDL.exe to generate a client side web proxy for a web service, called
the web service, got the results but an array returned by the web service is
not in the results.
However if I use "Add Web Reference" for the same service the same function
works appropriately.
Here is the client proxy generated from WSDL.exe

Can one use 'ref' ( or 'out' ) on a reference type to create a reference
to a reference in C#. I know one can use it on a value type to create a
reference to that value.

I am getting the following warning for the below function. I understand what
it means but how do I handle a null reference? Then how do I pass the
resulting value?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
