Namespace + functions versus static methods on a class
...ding the static ones.
Extension I
Adding code to a class' interface.
In C#, you can add methods to a class even if you have no access to it. But in C++, this is impossible.
But, still in C++, you can still add a namespaced function, even to a class someone wrote for you.

When NOT to use yield (return) [duplicate]
... because each enumerator is allocated on the heap. (On implementations of C# I'm aware of; a conforming implementation might have other stack or heap space characteristics.)
But iterating a tree can be O(n) in time and O(1) in stack space. You can write this instead like:

The bare minimum needed to write a MSMQ sample application

Web Reference vs. Service Reference
I just hit a huge brick wall with Paypal. I had created a regular C# project to create some wrapper classes using their WSDL.

Is MonoTouch now banned on the iPhone? [closed]
...their license agreement now that if the original application is written in C# then it would be violating the license:
...Applications must be originally written in Objective-C, C, C++, or JavaScript as executed by the iPhone OS WebKit engine...
They even hammer it in a little further:

Making interface implementations async

An abstract class can be used instead of an interface (in C# 7.3).
// Like interface
abstract class IIO

public virtual async Task<string> DoOperation(string Name)

I've used something similar in my C# port of ProtocolBuffers. There are "messages" (immutable) and "builders" (mutable, used to build a message) - and they come as pairs of types. The interfaces involved are:
