I'm creating a library for internal use that relies on third-party code. I
don't want clients of this library to know anything about the third party
code, when compiling or running. Generally I've been achieving this by having
an abstract base class which defines an interface, and inheriting a concrete
class which defines the implementation. Clients of the library deal only with
the base class and request objects of that type from a...

In the article, the description for
"Modiy DLL That Contains Consumers That Use Managed Code and DLL Exports
or
Managed Entry Points"
suggests the creation of the class ManagedWrapper.
If I need to build multiple mixed mode dll's used by a consumer application,
do I have to implement multiple ManagedWrapper's (each embedded in
indiviudal DLL project) and call all of them in my consumer application?

Meaning, myEXE is using a type defined in DerivedClass, which inherits
from BaseClass. I include a reference to DerivedClass in myEXE, which
gives this error:
The type 'BaseAssembly.SomeClass' is defined in an assembly that is not
referenced. You must add a reference to assembly 'BaseAssembly,

speaking of using linked lists. He gave and example which I found
confusing to say the least. So I rewrote the example in a way that I
could better understand the concept, he was trying to convey to me.
I ran my own example and it crashed and burn "what a surprise!" : (. I
ran the authors example out of the book and quess what, it crashed

I tried for an hour to find some reference to concrete information on
why this particular inheritance implementation is a bad idea, but
couldn't. So I'm sorry if this has been answered before. Here's the
scenario:
We have a base class with all virtual functions. We'll call this the
Animal class. We then make two classes Fish and Bird that both inherit
from Animal. In the program, we have a single array of Animal pointers
that will...

Hi Moondaddy,
I downloaded your sample project and run it and did see the problem on my
side.
There're three problems in the source code of your project.
1. You should move the following lines of code from the GetGeometry method
within the CustomPolyLine class:
_points.Add(new Point(10, 10));

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
Here is the code in...
