Okay, I'm in a debate over whether or not static methods are a good idea in
a general domain class.
I'm personally not a fan of static methods but we seem to be using them to
load an object. For example if you have an Employee class rather then
instantiating an instance you call a static method 'GetEmployees' and it
returns a List of Employee objects.
I'm looking for what other people are doing and if you feel this is a good
or bad...

I've been doing a lot of reading about static methods in Python, and I'm
not exactly sure what they are useful for or why they were introduced.
Here is a typical description of them, this one from Guido:
"The new descriptor API makes it possible to add static methods and class
methods. Static methods are easy to describe: they behave pretty much like
static methods in C++ or Java."

Why are there static methods in C#. In C++ static was applied to data only
(I believe) and it meant that the static piece of data was not a part of the
object but only a part of the class (one copy of data as opposed to multiple
instances of the class)
C# is now applying the static concept to methods. Why?, I thought that only
one copy of the methods were loaded into memory not matter how many
instances were created. Is this different...

Hello,
I wanted to get some feedback on why there are not allowed virtual static
members in C#.
Say, I have the Parent class, that hosts number of protected methods, that
occasionaly make calls to the virtual methods. When I create the Child
class, inheritting from the Parent class, and declare all of the Parent's
virtual methods with 'override', so that when these methods are called from
within the Parent protected methods, they...

Hi all,
I popped up this question a while ago, and I thought it was worth checking
again now... (maybe something has changed or something will change).
I read this book about component oriented design (owreilly - Juval Lowy),
and it was actually very nice.
The book goes on about how we should use Interfaces exposure instead of
classes (this is my terminology and english is not my language so I hope you
understand what I'm on about...).

We have an abstract class with all static methods. It makes sense to have
it static because there are no member variables and the constructor is
empty.
Some of the methods update the SQL Server database and we were wondering if
there would be a problem if two threads called that method at the same time.
Would it corrupt the database?
I was thinking about locking the code on entry and unlocking it on exit.

Hello,
I'm having a discussion with my colleagues (and boss) over the use of
static methods in a class.
My colleagues say that static methods should be avoided whenever is
possible, because their use slows down the application.
For me, this sounds absurd - I believe that static methods should be
used whenever they're necessary. However, I wasn't able to find any

Dear All,
For some time now, I have been working with the ctypes module on
Windows. First I got my hands on a library developed with Delphi 7.
That library is exporting plain functions. Internally, reference is
made to the instance of a class, which is instantiated in a kind of
initialization section. Everything works fine.
Now, I have developed a library in C#. I am able to get the result
from static methods, e.g.

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:

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,...
