Hi,
I have a class hierarchy, and would like all classes in
the tree to have a common, static readonly variable -
with a class-specific value. I'd like it to be readonly
(it should never change), but this prevents me from
setting its value in the static constructor of the
subclasses - I'm allowed to set its value in the
superclass constructor only.

I have a field in an abstract class marked readonly. However, when I attempt
to modify that field in the constructor of a class which inherits it, I get a
compile-time error stating that 'A readonly field cannot be assigned to
(except in a constructor or a variable initializer).' Any ideas would be
apreciated, though I was hoping I wouldn't have to use a property.

Hello,
I have a BaseClass and many Classes which all inherit (directly) from the BaseClass.
One of the functions in the BaseClass is to (de)serialize the (inherited) Class to/from disk.
1. The Deserialization goes like:

Is there any way to implement on a property or function who's return type is
an inheritor of the corresponding property or function in the interface? For
example, I would like to be able to do the following:
Public Interface ITest
ReadOnly Property TestProperty() As BaseClass
End Interface
Public Class BaseClass
End Class

However, I still don't understand the mechanism clearly.

If I create a UserControl that inherits from, say, Panel, and I do not want
my UserControl to have a property that it inherits from Panel. How can I
remove it.
For example, I might not want by control to have a BackColor property even
though it inherited that property from Panel.
Thanks

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,...

I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
